Installation Environment
Operating Temperature
The unit should only be operated between 0 and 40°Centigrade. If the unit is
operated at a higher temperature there is a possibility of a fire hazard. If the
temperature is changed rapidly from a cold environment to a hot environment,
moisture can be created internally which can cause malfunction or damage the
unit. Allow the unit to sit for 30 minutes without power applied to reduce any
possibility of condensation. If the temperature rises above 60°Centigrade a
warning dialog will be given. If the temperature rises above 65°Centigrade the
unit will be turned OFF. Under both conditions, an event will be added to the
event log to show what happened.
Input/Output Terminals
Do not connect the input or output BNC connectors to external power as this can damage the
internal circuitry and cause the unit to work incorrectly.
The BNC connectors fitted on this unit are 75Ω type which are not compatible with 50Ω plugs.
The use of 50Ω plugs will permanently damage the connectors on the unit. The
use of 50Ω plugs is considered to be misuse of the equipment and will therefore
invalidate the unit’s warranty.
When Not In Use
Disconnect the unit from the power supply and AC power source when not in use.
Maintenance
Wipe the case, and knobs gently with a soft cloth, lightly dampened with a neutral cleaning
agent. A screen cleaning cloth may be used to clean the LCD. Do not apply force to the LCD
when cleaning or it may be damaged.
Remove the power supply from the unit and turn OFF before cleaning. Do not
allow any water or other liquid to enter the unit while cleaning.

Rx Platform
Overview
The ‘Rx platform’ has been designed to serve the varied test and measurement needs of the
broadcast industry. PHABRIX has developed not a single product in the traditional sense but a
modular system from which specific broadcast client requirements can be satisfied.
Description
The Rx platform allows a flexible approach to test and measurement on a new technological
platform designed for longevity. The system has been created to allow broadcast engineers to
specify features according to the complexity of the required test and measurement application
by simply adding additional modules and software licenses to their chosen core chassis.
Adding modules is like adding independent new instruments, each module providing a
dedicated set of instruments for the task required.
The Rx Platform is available in a choice of chassis types:
Rx2000 – a unique audio video monitoring solution combining front panel
instrumentation, via dual TFT screens, and integrated full range stereo speakers. Unique
2U tapered ‘tilt-in-bay’ engineering with four Rx module bays.
Rx1000 rasterizer – a compact 1U 19” rack-mount chassis with OLED display interface
with four Rx module bays.
Rx500 rasterizer – a compact 1U ½ rack width chassis with OLED display interface with
two Rx module bays.
Rx 2000 Operaon Manual 1–3PHRX2000-201 8

Description
Rx2000
Description
The Rx2000 is a 2U rack mounted instrument that provides the following:
Two front panel TFT screens, one with a full range of generator, analyzer and system
control menus, and selected analyzer instrument panels such as Waveform monitor,
Vectorscope and Eye Pattern display; and the other to display the selected input image
and other instruments, along with Input, Preset, and System Reference buttons.
Both TFT screens can be used to display instruments at the same time.
Rasterised HDMI/SDI outputs to allow up to 16 individual instrument panels (windows)
to be displayed on a single DVI 1920 x 1080 resolution monitor. Ideal for outside
broadcast facilities and engineering bays where space is at a premium.
Individual input selection, for instant confidence and monitoring of feeds, using
dedicated source selection buttons.
Control via front panel controls, for in-bay use and remotely via a network connection
using a web browser.
Front panel audio monitoring, provided by high quality speakers and/or a head phone
socket, to allow the monitoring of the selected Audio channel.
4 Module slots allowing the installation of Analyzer and Generator modules.
Front Panel
The front panel provides access to the Video Confidence Display, the Instrument Display and
menu system.
Rear Panel
The rear panel provides the Rx instrument’s connections via the CPU module and the installed
Analyzer or Generator modules. See the “Modules” section for details of the different module
types.
The power for the Rx instrument is provided by a separate PSU unit that connects to the 4-pin
male XLR connector at the left of the instrument.

Overview
The Rx range can be configured with a range of plug-in modules (printed circuit boards with
dedicated hardware for specific functions) that enable functionality in the software an allow
different menus to be selected on the front panel (Rx2000) and allow different Instrument
panels (windows) to be created on the Monitor output.
Note that the Monitor Output - “System Status” menu can be used to inspect which Modules
have been installed in the Rx instrument. See the “Monitor Output” section for details.
CPU Module
At the heart of every Rx product is the CPU module. Here signals from each installed
instrument module are processed to provide a variety of instrument displays. Unhindered by
stacked processing restraints, the CPU board creates an output display at an industry leading
1920 x 1080 pixels with perfect scaling via simultaneous HDMI and/or SDI outputs. In practice
the Rx acts like a Test & Measurement multi-viewer providing scaled instruments from any
selected video/audio input.
Description
The CPU board also provides AES input, Bi/Tri level looping reference, 8 channel GPI, LTC input
and stereo analogue audio output. Dual USB ports are provided for mouse and keyboard
control. Ethernet provides remote access via web browser and is also the method for updating
firmware and software from PHABRIX’s dedicated server.
REF Bi/Tri level looping reference that allows the Rx instrument to be locked to a studio
reference.
AES IN Is an AES audio input
SDI OUT Is an SD-SDI or HD-SDI signal generator output that provides test signals
generated by the on-board Generator module on the CPU board. This output can
also be used to provide an SDI monitor output tied to the HDMI® monitor output.
HDMI Is a DVI 1920 x 1080 resolution monitor output that allows up to 16 individual
instrument panels (or windows) to be displayed.
Note that on some HDMI® monitors this output may appear too sharp causing
ringing on the edges of text and menus. This can be resolved by reducing the
monitor’s image sharpness setting.
USB Are standard USB 2 connections provided for connection of a keyboard and
mouse to control the HDMI® monitor output.
LAN 10/100-base-T connection allowing the Rx instrument to be connected into a
network and accessed via TCP/IP so that it can be controlled remotely.
GPIO Provides a GPI (general purpose input), LTC control and analogue audio
connections.

Rx Software Options
Overview
The Rx range has a range of software options that can enhance the Rx functionality for specific
applications.
3G-SDI and advanced formats upgrade for Rx chassis
3G-A
Among the support for 3G level B is the ability to analyse signals such as SMPTE 425-B
carrying 1 x SMPTE 372M Dual-Link payload. Generation of these signals is activated if the
generator is present.
HD/SD-SDI Data Analyzer and Ancillary Packet analyzer

YCbCr-422-12
YCbCr-444-12
RGB-444-10
RGBA-4444-10
RGB-444-12
This option (PHRXO-3G) provides advanced
formats include 4:2:2 YUV, 4:4:4 RGB and
4:4:4 YUV at 10/12 bit and 3G level A and
B. For broadcast manufacturers this option
allows rigorous testing of many more
formats beyond the standard signals used
in traditional broadcasting.
The SDI analysis option (PHRXO-SD)
provides the engineer with a detailed view
of the data words contained within the
SDI stream. This allows the analysis of
complex faults and is particularly useful
when determining compatibility issues
between equipment and when debugging
new product developments particularly in a
R&D environment.
Detail within the active SDI stream can be viewed with continuous update.
The SDI Analysis option provides the following functional areas:
Grid displays the SDI data in the form of an array.
Stream allows the SDI continuous data stream to be viewed.
Component allows the video components to be displayed in separate columns.
Splt allows the video components to be display individually.
Ancillary Data allows the user to capture whole Ancillary data packets identified by their
data id (DID).
Ancillary Status allows additional ‘user defined’ selections with the appropriate DID or SDID
code.
Access to the SDI analysis functionality is via the Analyzer - Signal Data menu. See the
“Analyzer - Signal Data” section in chapter 2 for full details.

Page 25
Advanced physical layer analysis
The analysis option (PHRXO-EA) for the
Rx range adds an additional jitter screen,
plus enhancements to the eye display.
The extra features added to the eye
and jitter module are focussed toward
broadcast manufacturers who have a need
for high end analysis tools. Histograms,
decade filters, multiple eye display, full
screen jitter display and alignment and
timing thermometers are all available with
comprehensive logging.
The Advanced physical layer analysis option provides the following functional areas:
Multi eye display enables analysis when serialiser jitter is present: Products process video in
either a 10 or 20 bit parallel data domain which is subsequently transmitted
as a single bit serial data stream. By triggering every 10 or 20 eyes you
can reveal repetitive parallel/serial clock domain jitter in equipment being
analysed.
Histograms give statistical information which can be used to accurately measure rise
time, fall time and amplitude. These automatic accurate measurements can
then be logged for extended periods of time. Measurements like rise time
and fall time are notoriously difficult to make with SDI signals.
Description
In addition to the standard timing and alignment jitter filters, decade filters
are provided allowing an engineer to analyse the frequency content of any
jitter present. The number of eyes displayed is adjustable from one eye up
to one frame of eyes.
Decade filters are provided allowing an engineer to analyse the frequency content of any
jitter present. The number of eyes displayed is adjustable from one eye up
to one frame of eyes.
Jitter display the separate full screen jitter analysis display incorporated into the
advanced option enables the engineer to analyse the nature of jitter present
using a graph of jitter versus time. Again, the decade filters are present and
the time base can be adjusted from 1 line through to 1 frame. By analysing
jitter in this detailed way an engineer can determine if a signal is in or out of
specification and also get a feel for where any problems lie.
Enhanced remote control
The Enhanced remote control option gives
users full remote control of the unit via TCP/
IP Sockets to allow any aspect of the unit to
be modified or queried.
This allows complex applications to be
created to perform test and measurement
functions such as automated testing of
routers or other broadcast equipment.
Rx 2000 Operaon Manual 1–9PHRX2000-201 8
Page 26
Description
The Rx instrument can act as a server and listen on a port waiting for incoming requests from
clients such as a PC. Using this method of communication the Rx range can provide a variety
of information to the control device it is connected to and be controlled in specified areas of
the product using the command details included. All visual controls on the product have an
associated command.
Messages may be sent to ‘set’ or ‘get’ data from a command ie if you ‘set’ a value the unit
will be configured accordingly and a reply returned and if you ‘get’ a value from the PHABRIX
unit it will reply with that value. All messages are acknowledged to increase the security of the
interface ie closed loop communication.
The control structure can be selected as Passive or Active. Passive control allows simple remote
control where the host PC is in control and sends commands when it wants to change data or
get information. It is this method which is the most popular use for remote control.
Active control is when the Rx unit synchronizes with the host PC. Any changes on the Rx unit
will result in a message being sent to the host PC. This method is useful for controlling a Rx unit
from another unit or via the PC simulator software. It requires more complex software on the
host to respond to the returned messages.
The option provides a programming guide with command information and examples on a CD. A
Windows™ application for testing the interface is also provided as part of this option.
See the Remote Control Guide for details.
Dolby Metadata Generator
The Dolby Metadata Generator software
option (PHRXO-BDG) allows generation of
Dolby-E, Dolby Digital and Dolby Digital
Plus pre-encoded test signals to check that
they are transferred transparently through
the broadcast chain unaffected by routers /
switchers, satellite links, etc.
Dolby analysis
The Dolby-analysis option (PHBRO-BDA)
displays Dolby E, Dolby Digital and Dolby
Digital Plus metadata present in a selected
audio stream and determines whether a
Dolby-E packet is timed correctly on the
SDI video stream. The Dolby audio may
be monitored from any of the SDI input
embedded audio channel pairs or AES
input.
Peak metadata audio levels metering is also displayed for Dolby E.

SDI-2K Formats
4 Channel Loudness
Description
This option (PHRXO-2K) supports the new
SDI practice for HD and 3G Level A and
Level B signal transfer of 2K advanced
formats including 4:2:2 Y’C’bC’r, 4:4:4
R’G’B’ and 4:4:4 Y’C’bC’r at 10/12 bit.
This option (PHRXO-4LOU) allows up
to 4 channels of loudness metering and
monitoring to be performed by the Rx unit
(1 loudness channel per analyser module).
The tools provided in the “Loudness” window allow the loudness of the selected stereo audio
pair or 5.1 surround audio group to be monitored and measured. The Rx system provides a
single Loudness meter as standard and an additional 3 Loudness meters are available as an
option. The Loudness meters are access via the Analyser module menu on the HDMI® monitor
output.
The Loudness Setup allows the meter scale (LU, LUFS or LKFS), measurement standard (EBU or
ITU) and Meter Range as well as user-defined threshold values for Integrated, Momentary and
Short Term loudness.
4 Channel Closed Caption
This option (PHRXO-4CAP) allows up to 4
channels of closed caption to be displayed.
This is allocated as 1 channel per analyser
module.
This supports WTS/OP42/OP47, EIA 608
and EIA 708 closed caption / subtitle
formats.

Using the Menus
The Menu buttons select which instrument is in use as well as selecting the options for the
instrument. The bottom of the LCD display shows the function of each Menu button.
When in a specific function eg Generator, Analyzer etc, the cursor controls () on the
right hand of the instrument select a field to edit. The current field has a red box around it.
Pressing the OK button starts or ends editing of that field. Check boxes are always in edit mode
and pressing the OK button inverts the current state.
When editing some types of fields, the menu buttons at the bottom take on different
functionality to allow cancelling edit mode or setting the value for the field. When lists of
options are displayed the menu buttons allow selection of the first/last item in the list as well
as paging through the available options. If the list of items is small, the available items may be
displayed on the menu buttons for instant access.
The buttons along the bottom of the LCD display change the currently displayed page when
not editing a data field. The left hand button always selects the top level menu and system
overview page. So for example pressing the first button will select the “Main Menu”, selecting
the second button will select the “Generator” menu, etc.
The Main menu is the top level menu from which all other menus are selected on the Rx2000
instrument. The main menus are:
Generator (only present if a Generator module is fitted) allows video test pattern
selection to be made and audio test tones to be selected.
Analyzer allows the selected input signal to be analysed in the form of a Picture,
Waveform monitor, Vectorscope and Eye Pattern display (option).
Sig Info allows detailed signal information about the video and audio status for the
analyzer source to be displayed.
Audio gives access to the Audio Meters and Audio Status displays.
System allows the setup of system wide settings including memories, date/time and
software.
Logging selects the logging page to view and setup the error logging system.
Speaker selects the speaker/headphone setup page.

Multiple Analyzers
The Analyzer module resource used by the Rx2000 front panel is directly linked to the
selected input source. If for example the “SDI1a” input is selected this will use Analyzer 1 (ie
the first analyzer channel found in the first occupied Module slot). If “SDI2a” is selected it will
use Analyser 2 (ie the second analyser channel).
Selection of inputs using the Rx2000 front panel (left-hand bank of buttons) will automatically
re-assign the analyser resource used by the HDMI® monitor output affecting its use. Note that
Bank 1 on the left hand screen gives access to input “SDI1a” through to “FIB2b” and Bank 2
gives access to inputs “SDI3a through to “FIB4b”.

the instrument being displayed.
Note that for Dual Link analysis the Link 1 signal must be connected to “IN1” BNC connector
and the Link 2 signal must be connected to “IN2” BNC connector on the same Anayzer module.
Likewise if Fibre is being used Link 1 should connect to “OPTICAL A” and Link 2 should connect
to “OPTICAL B”

Front Panel
Generator
When multiple generator modules are installed, the one to be controlled can be selected from
the drop down list.
Output On
The Output On function turns ON the output circuitry. On Rx instruments that have dual
generator modules, there is the option to turn on output 1 and output 2 which correspond to
the 2 generator outputs.
Note that for Dual Link test pattern generation both Output 1 and Output 2 must be enabled.
The Link 1 signal is produced on the module’s “GEN A” output and the Link 2 signal is
produced on the module’s “GEN B” output. Likewise if a Fibre connection is being used the Link
1 signal is produced on “OPTICAL GEN A” and the Link 2 signal is produced on “OPTICAL GEN
B ”.
Standard
The menus in the Standard section are used to select the desire video output format. The topleft box selects the basic mode of the Rx instrument and determines whether it is generating
normal SD/HD vide or 3G level A or level B video. Dual streams refer to the ability of the Rx
instrument to generate two separate pictures when transmitting 3G-level B in some formats.
Which mode is selected determines which formats are available. Only valid frame rates for the
output standard may be selected.

This selects the video pattern that is output by the generator. Many standard patterns
are provided by the Rx instrument. You may also upload your own test patterns to the Rx
instrument into the ‘Patterns’ directory and then select them using the ‘User File’ option in
this field. See the ‘File Structure - Patterns’ section for file formats supported. If a ‘User File’
has been selected, the ‘i’ button beside the file can be selected to get information on the file
properties. Unsupported file types will be displayed as a black image. If the video standard is
changed while a user file is loaded and there is no file for the new standard present, a black
image will be loaded and the User File blanked.
A bouncing Box may be overlaid on the current test pattern by selecting the Box check box
field.
Colour Bars test patterns are used to check that the colour gamut of the television system and
to ensure the correct luminance and chrominance levels.
The “100% Colour bars” test pattern is produced by using combinations of
the Red, Green and Blue primary colours:
White (100% R, 100% G, 100% B)
Yellow (100% R, 100% G, 0% B)
Cyan (0% R, 100% G, 100% B)

The “Tartan bars” test pattern is a chequerboard pattern of 75% colour bar
colours that produces every combination of colour vector change.
The “SMPTE Colour bars” test pattern was developed for the NTSC analogue
video standard and produced by using the combinations of the Red, Green
and Blue primary colours as used in 75% colour bars.
The “SMPTE ARIB STD-B28 Colour bars” test pattern is an updated version
of SMPTE colour bars (developed by the Japanese Association of Radio
Industry and Businesses) and standardized as SMPTE RP 219-2002 and is
used to test both 4×3 standard definition and 16×9 high-definition video
signals.
The AV Delay Test pattern and audio tone provided by the Generator
module can be used to check any delay between the video and audio. This
animated test pattern provides a constantly moving Clapper board and
corresponding AV Delay tone when the clapper board reaches the centre of
the test pattern.
The “Multi-burst” test pattern is used to check the frequency response of
the video path and check that it has not been affected by digital processing
such as resizing, standards conversion or colour grading. The frequency of
each burst will depend on the video format selected. For example:
Front Panel
For SD 720 pixels:
0.5MHz 1.75MHz 2.5MHz 3.5MHz 4.5MHz 5.5MHz
For HD 1920 Pixels:
5MHz 7.25MHz 15MHz 20MHz 25MHz 30MHz
The “Bowtie” test pattern is used to check the alignment of the luminance
and chrominance components through television equipment.
The Ramps and Steps test patterns are used to check the linearity of television equipment to
ensure that there have been no digital bit level artefacts such as rounding errors introduced
that may cause banding on the television pictures.
The “Luma Ramp” test pattern is used to check the linearity of the
luminance component. This test pattern exercises all of the discrete digital
video levels including illegal values below video black and above peak white.
The “Legal Ramp” test pattern is used to check the linearity of the
luminance component. This test pattern exercises all of the discrete digital
video levels from video black to video white, excluding illegal values.
The “Valid Ramp” test pattern is used to check the linearity of the Y
(luminance), Cr (R-Y) and Cb (B-Y) components. This test pattern exercises
all of the discrete digital video levels of these components, excluding illegal
values.

The “Grey Bar - 5” test pattern is used to check for non linear distortion in
the luminance component. The bars range from 100% white to 0% black
in 20% steps. Typically non linearity will be seen as a loss of grey-scale
distinction.
The “Grey Bar - 11” test pattern is used to check for non linear distortion in
the luminance component. The bars range from 100% white to 0% black in
10% steps.
The “Grey Bar - 5 Vertical” test pattern is used to check for differential gain
distortion in the luminance component line by line. The bars range from
100% white to 0% black in 20% steps. Typically non linearity will be seen as
a loss of grey-scale distinction.
The “Grey Bar - 11 - Vertical” test pattern is used to check for differential
gain distortion in the luminance component line by line. The bars range from
100% white to 0% black in 10% steps.
The “Pluge” (picture line-up generation equipment)test pattern is used
to adjust the black level and contrast of a video monitor. The pattern
consists of vertical luminance bars for white, mid grey, black and super
black.
The Colour Field test patterns are used to provide primary colours (such as 100% red, green,
blue, cyan, magenta and yellow) and monochrome luminance levels to check for calibration and
banding effects caused by encoding/decoding processes.
If colour field is the selected test pattern, another control selects which colour to generate.
Three user definable custom colours may be defined using the “->” button. Custom colours
are edited using the Red-Green-Blue sliders. When setting the colour using the RGB sliders, the
YCbCr values will show the values for the current colour space. When setting the colour using
the YCbCr sliders, the RGB values will show the values for the current colour space.

The Zone Plate is a 2 dimensional linear frequency sweep test pattern used to check the affect
of filtering, sub-Nyquist, sampling, processing standards conversion and display. Whenever
an image is re-sized or re-sampled there is a strong probability that the resultant image will
suffer from one or more of the artefacts such as aliasing / moire, softening (caused by reduced
frequency response) and ringing / halos.
The “Zone Plate” test patterns are used to check that the horizontal and
vertical frequency response of the video path is not affected by television
equipment.
The zone plate selector will contain 3 user customisable zone plates as well as several predetermined zone plates. The ‘->’ button displays a dialogue which allow the parameters of the
zone plate to be adjusted for the custom zone plates. Any of the preset zone plates may be
copied to the custom zone plates to act as a starting point for a new zone plate. As the zone
plate settings are stored in user memories a large number of custom zone plates are available:
Moving Zone-2H - A moving zone plate centred on the screen.
Static Zone-2H - A static zone plate centred on the screen from DC to the nyquist
frequency at left/right edges.
Static Zone-2V - A static zone plate centred on the screen from DC to the nyquist
frequency at top/bottom edges.
Sweep-Horiz - A horizontal sweep from DC to nyquist frequency horizontally.
Front Panel
Sweep-Vert - A vertical sweep from DC vertically.
Grating-50kHz - A 50kHz frequency sine wave when using an HD output.
Grating-1MHz@HD - A 1MHz frequency sine wave when using an HD output.
Grating-5MHz@HD - A 5MHz frequency sine wave when using an HD output
Custom allows editing of Custom zone plate settings. Three custom zone plates can be set up
and can be copied from an existing presets using the ‘Copy To’ button.
Mode - sets which type of Zone Plate is being produced. It may be Zone Plate (circular
pattern) Grating (Linear horizontal or vertical grid) Sweep (Frequency sweeps from start
to end Frequency)
Start Phase - sets the start phase of the sine wave generated by the zone plate generator
and is set in degrees from 0-360
Phase Rate - is used to set the rate of change of phase of the sine wave and thus
changes the speed that the zone plate moves at. It is specified in degrees per frame.
Angle - changes the angle of the zone plate and thus can change a horizontal sweep into
a vertical sweep or rotate an elliptical zone plate pattern.
XScale/Start Freq - sets the horizontal scale of grating patterns or the start value of the
zone plate sweep frequency.
YScale/End Freq - sets the vertical scale of grating patterns or the end value of the zone
plate sweep frequency.

The Pathological test patterns are used to check that the phase locked loop circuitry used to
decode SDI data can recover/regenerate the SDI sample clock under worst case conditions.
EQ Test is a pathological signal that generates long run-lengths of 1s or 0s
(for example 19 samples of 0 followed by a single 1) to test the accuracy of
phase lock loop circuitry that recovers/the sample clock from the SDI data.
PLL Test is a pathological signal that generates a pattern of 2 consecutive
1s followed by 2 consecutive 0s repeated for the whole pattern. This is the
worst-case to test phase lock loop circuitry that recovers/regenerates the
sample clock from the SDI data.
Check Field is a pathological signal that generates long run-lengths of
1s or 0s to test the accuracy of phase lock loop circuitry that recovers/
regenerates the sample clock from the SDI data. This is a combination of
the EQ Test pattern and the PLL Test Pattern.
If Check field/Pathological is selected when a dual stream format has been
selected, BOTH outputs will be forced to check field due to internal hardware
limitations. If another pattern is selected, the Check field pattern will be deselected. The exceptions to this are when Colour Field or Zone Plate are selected
as test patterns.
The Check field/Pathological/PLL Check/EQ Check patterns will only look like the picture above
when a YCbCr 422 10 bit colour mode is selected. Other colour modes will have different
pictures but still create the SDI data stream required by SMPTE.
EDH
If the output signal is SD (PAL-625 or NTSC-525) the insertion of EDH information may be
turned on or off.
Errors
This field enables the insertion of CRC or EDH errors into the video signal. This allows checking
of third party error detection circuitry. In SD there is one EDH ancillary packet per field. When
errors are being inserted every EDH value gets deliberately corrupted. This creates one error
count per field. (Actually one AP error and one FF error). In HD there is a CRC value calculated
for each line. When errors are being inserted the CRC value on line number 1 gets deliberately
corrupted. This creates one CRC error count per frame. There is also the option to generate
CRC errors (not SD EDH errors) on only the switching line in field 1 which can be used to check
that any downstream equipment ignores errors on switching lines.
SMPTE 352
This check box allows the SMPTE 352 Payload ID field to be inserted into the video output
stream. The state of this check box is stored separately for SD, HD and HD-3G line standards.
Note that for HD-3G line standards the Payload ID should be turned ON.
Ident
An picture or text ‘Ident’ may be set to identify an SDI source. This Ident can be turned on/off
from this page but changing the text/font/bitmap is performed by selecting the Edit button to
bring up the Ident Dialog. An overview of what the Ident is can be seen beside the Edit button.
Note: If zone plate or colour field are selected, text cannot be overlaid over them. A smaller

Genlock Menu
The Rx instrument with a Generator Module installed can create video test signals that are
either free-running or locked to a studio reference signal. The Genlock menu is used to select
an external locking reference or set the instrument to free run.
Using the Rx 2000 front
panel, the Genlock menu can
be displayed by selecting the
corresponding “Generator”
button.
When using an external locking reference signal, the Rx system will provide the best possible
locking regardless of the locking reference frame rate and the generated frame rate.
When the frame rate of the locking reference is exactly the same as the generated frame
rate, there will be an exact lock vertical and horizontal between them.
Front Panel
When the frame rate of the locking reference and the generated frame rate are divisible
(for example 50/25, 60/30, 59.94/23.98) there will be an exact lock vertical and
horizontal between them.
When there is no relationship between the frame rate of the locking reference and
that of the generated frame rate (for example a 625/50 locking reference and a 23.98
generated test pattern) then there will be a static lock between them but this will not be
consistent.
Source
The generator may be locked to an input reference which may be either the reference input
which is a Bi-Level/Tri-Level sync or may be locked to the video input. Alternatively, the
generator may free run.
Delay
The test patterns generated by the Generator module can be delayed or advanced with respect
to the locking reference input using the Lines and Pixel values.
System Reference
The drop down menu allows the selection of the system locking reference. This can be the
external locking reference signal or one of the SDI inputs.
The System Reference defines the video source that the Rx system is synchronised to and
affects all of the Rx outputs:
the on-board test pattern generator output from the CPU SDI connector,
the Generator module SDI outputs,
the HDMI monitor output,
the AES audio outputs,
The System Reference can be set to one of the following depending on the type of modules
installed within the Rx chassis:
Rx 2000 Operaon Manual 2–17PHRX2000-201 8
Page 46
Front Panel
Free Run - where the Rx system uses its own internal locking reference.
Ext. Ref - where the Rx system is locked to an analogue studio reference signal
connected to the “Ref” input on the CPU module.
SDI1 - where the Rx system is locked to the SDI input on a single input Analyser module
fitted in module slot 1.
FIB1 - where the Rx system is locked to SFP optical input on a single input Analyser
module fitted in module slot 1.
SDI2a - where the Rx system is locked to the SDI “a input” on a dual input Analyser
module fitted in module slot 2.
SDI2a - where the Rx system is locked to the SDI “b input” on a dual input Analyser
module fitted in module slot 2.
Note that System Reference selection can be saved as part of a preset. To do
this ensure that the “Video” check box is selected in the “Analyser” section of the
“System Presets” menu.
Ideally the Rx system should be locked to an external studio reference all analyser inputs
should be of the same frame rate as the locking reference and synchronous to the locking
reference.
External Reference can be used in most applications where a studio locking reference is
available and is used to ensure that all outputs from the system are locked to the studio itself.
In applications where Dolby E, Dolby Digital or Dolby Digital Plus is being analysed or decoded,
the System Reference should be set to external reference unless one is not available in which
case the System Reference should be set to the specific SDI input where the Dolby digital audio
is embedded.
In situations where there is no studio reference or when the SDI input is asynchronous and
when decoding Dolby audio or routing embedded SDI audio channels to the AES output (4AES
module) then the System Reference should be set to the SDI input containing the Dolby audio
or embedded audio channels.
Note that the level of Generator jitter produced by the Rx is determined by the System
Reference being used. If the Rx is locked to an SDI or SFP Fibre input, while jitter
measurements are being made, then the measured jitter will include the Rx chassis’s own input
locking jitter plus SDI output jitter. This mode of operation may produce out of specification
jitter.
Free Run should be used when using Analyser / Generator modules to perform closed loop
testing especially if Eye and Jitter measurements are being made.

Overview
There are a number of Dolby broadcast digital audio standards that transport audio data over
an SMPTE 337M AES carrier with a 48kHz sample rate. The type of Dolby to be generated can
be selected from the drop down list in the top left corner of the menu:
Dolby E
Dolby Digital
Dolby Digital Plus
These standards can be used to transport mono, stereo, 5.1 and 7.1 audio programmes:
Dolby 5.1 - involves five channels for normal-range speakers (20 Hz – 20,000 Hz) (right
front, centre, left front, rear right, rear left) and one channel (20 Hz – 120 Hz allotted
audio) for the subwoofer driven low-frequency effects.
Dolby 7.1 uses six channels in the primary program (Independent Substream) for a
standard 5.1 surround sound mix and then the 2 remaining 2 channels in an ancillary
programme (Dependent Substream) to provide the additional down-mix.
Dolby E
Dolby E is an audio encoding and decoding technology developed by Dolby Laboratories that
allows up to 8 channels of audio (mono, stereo, 5.1 or 7.1) that for a primary programme
(Programme 1) and optional ancillary programs. These 8 channels are compressed (loss-less)
into a digital stream that can be transferred between compatible devices and stored on a
standard stereo pair of audio tracks.

Dolby Digital
Dolby Digital (AC-3) is a ‘perceptual audio’ system for digital audio that allows the reduction
of data needs to deliver high-quality sound. This system was developed primarily for DTV, DVD
and HDTV. This format allow up to six channels of sound (mono, stereo or 5.1) in the form of a
single ‘program’ that can be delivered at different bit rates. These 6 channels are compressed
(lossy) into a digital stream that can be broadcast. The most elaborate mode in common use is
Dolby 5.1 with uses all six channels to provide surround sound.
Dolby Digital Plus
Dolby Digital Plus (E-AC-3) is a more advanced version of Dolby Digital that provides a more
efficient encoding algorithm that provide enough bandwidth that allows up to 20 channels of
audio (mono, stereo, 5.1, 7.1 up to 13.1) that for a primary programme (Programme 1) and
optional ancillary programs that can be delivered at much lower bit rates than Dolby Digital.
These 20 channels are compressed (lossy) into an independent digital data stream plus up to
8 dependent sub stream that can be transferred between compatible devices and stored on a
standard stereo pair of audio tracks.
Dolby E Synchronisation - Generator Reference
The Dolby audio test signal produced by the Rx instrument is common to all generator
modules within the system and is locked to either one of the generator video formats or to the
System Reference (typically external reference).
If the Dolby Generator is locked to an external signal, the reference signal MUST have a
compatible frame rate. See the table below for examples.

Editing Program Information
Stream type: Dolby-E, Dolby Digital and Dolby Digital Plus streams can be generated.
Config, Bit Depth: The program configuration and Bit Depth can be changed to load the pre-
encoded file.
Stream contents: The tones generated are of a fixed predefined frequency. Four sets of pre-
encoded streams are provided:
Ramp Var - Each channel has a different frequency to allow checking of
channels. The levels are ramped so that different channels have different
levels.
-3dB Fixed - All the tones are at -3dB co-phased / timed and are at the
same frequency.
-18dB Fixed - All the tones are at -3dB co-phased / timed and are at the
same frequency.
-20dB Fixed - All the tones are at -3dB co-phased / timed and are at the
same frequency.
Fixed Frequency values for “Fixed level“streams above:
Frame Rate Normal Frequency LFE Frequency
23.98 4.8kHz 211Hz
24 6kHz 240Hz
25/50 6kHz 240Hz
29.97/59.84 6kHz 133Hz
30/60 6kHz 240Hz
Front Panel
Dolby-E start line: The start line can be used to set valid or invalid ranges to allow checking of
the Dolby-E guard band on downstream equipment. If the start line is set
outside the valid range specified by Dolby, the line number will be displayed
in RED.
Relative to Ideal If this check box is checked, the line number displayed is relative to the
Dolby specified ideal line. A value of ‘0’ therefore starts the Dolby-E packet
on the ‘Ideal Line’ for that video format.
Frame Rate This is set by default to the currently generated frame rate but may be
modified by the user to test downstream equipment.
Original rate This is set by default to the currently generated frame rate but may be
modified by the user to test downstream equipment.
Note that if generating a progressive fast rate video standard such as 720p50,
720p59 or 720p60 etc. The Dolby-E signal will always be generated at the
related slower rate. This is a Dolby restriction as the packets are over 1 frame in
length for these video formats.

Program Meta Data Editing
Many of the metadata fields may be edited to test downstream equipment. The Channel Mode
field may be edited to invalid settings but they will be shown in RED to show that they are
invalid. The settings currently being edited are for the selected program but multiple program
metadata values can be modified and the settings for all programs are stored in memories.
Metadata changes and line changes will happen cleanly so that no corruption to the Dolby
signal will occur.
A maximum of 30 characters may be used for program description text. If the text is longer
than this, extra characters will be ignored.
The “Generator” – “Dolby” menu allows the metadata for a Dolby E data stream to be setup for
testing purposes. The main purpose of setting these metadata fields is to check that they are
transferred transparently through the broadcast chain unaffected by routers/switchers, satellite
links, etc. For any programme this metadata would be created as part of Dolby E authoring
process. Using the Dolby generator, the following metadata can be setup for Program 1:
Dialogue Norm is the normal audio level for dialogue. Ideally all transmitted programs
would have the same value.
BsMod (Bitstream Mode) indicates the type of audio service that the bitstream
contains. Complete Main (CM) is the normal mode of operation and contains
a complete audio program including dialog, music, and effects.
Ctr DnMix (centre down-mix) is a weighting value used in the encoding and decoding of
surround sound mixes for a Dolby 5.1 Independent Substream.
Sur DnMix (surround down-mix) is a weighting value used in the encoding and decoding
of surround sound mixes for a Dolby 5.1 Independent Substream.
LRoCtrDnMix (left/right/stereo/centre down-mix) is a weighting value used in the encoding
and decoding of surround sound mixes for a Dolby 7.1 Dependent
Substream.
LRoSurDnMix (left/right/stereo/surround down-mix) is a weighting value used in the
encoding and decoding of surround sound mixes for a Dolby 7.1 Dependent
Substream.
LR CtrDnMix (left/right/centre down-mix) is a weighting value used in the encoding and
decoding of surround sound mixes for a Dolby 5.1 Independent Substream.
LR SurDnMix (left/right/surround down-mix) is a weighting value used in the encoding and
decoding of surround sound mixes for a Dolby 5.1 Independent Substream.
Chan Mode defines the channel configuration for Program 1 (ie mono, stereo, 5.1
channels).
Line Mode this is an Operational Mode / Dynamic Compression Mode that is used
by consumer and professional decoder products that simplifies the
implementation of Dialogue Normalization, Dynamic Range Control, and
down mixing functions, all of which are necessary in Dolby Digital products.
RFMode this is an Operational Mode / Dynamic Compression Mode that is used
by consumer and professional decoder products that simplifies the
implementation of Dialogue Normalization, Dynamic Range Control, and

DolbySurnd the Dolby Surround Mode parameter indicates whether or not a two-
channel Dolby Digital bitstream is conveying a Dolby Surround encoded
program.
DownMixMod this controls the Down Mix Mode which is used by the content creator to
optimize Center and Surround channel levels for use in stereo down mix
mode for any two-channel programmes.
D Sur Ex this controls the Dolby Surround Ex channel that provides an extra audio
channel for Dolby 5.1. The extra surround channel of the Dolby Surround
Ex system is matrix-encoded onto the discrete left-surround and rightsurround channels of the 5.1 mix.
The following control bits can also be set:
LFE the LFE Channel parameter enables or disables the Low-Frequency Effects
(LFE) channel.
HPF this parameter can be used to activate the DC High pass filter for all input
channels.
LPF the LFE Low pass Filter parameter can be used to activate a 120 Hz low-
pass filter applied to the LFE input channel.
Sur 3dB Alt the Surround Channel 3 dB Attenuation function is use to apply a 3 dB
attenuation to the Surround channels of a multichannel soundtrack created
in a room with film style calibration, when encoding it for consumer home
theater playback.
Front Panel
Sur Ph+Filter the Surround Channel 90-Degree Phase-Shift feature is used for generating
multichannel Dolby Digital bitstreams that can be down-mixed in an
external two channel decoder to create a true Dolby Surround compatible
output.
Org Stream the Original Bitstream informational parameter sets the value of a single bit
within the Dolby Digital bitstream. This bit has a value of 1 (box checked)
if the bitstream is an original. If it is a copy of an original bitstream, it has a
value of 0.
Copyright the Copyright Bit informational parameter sets the value of a single bit
within the Dolby Digital bitstream. If this bit has a value of 1 (box checked),
the information in the bitstream is indicated as protected by copyright. If it
has a value of 0, it is not copyright protected.
RF 0v Prot the RF Over-modulation Protection parameter determines whether or not
an RF pre-emphasis filter is used in the overload protection algorithm to
prevent RF over-modulation in set-top box decoders.
Default Program Meta Data
Pressing the “Default” button will return program metadata settings to their default values.
Embedding Dolby on SDI Stream
To embed Dolby signals on an SDI stream, the Audio source for that channel should be set
to ‘Dolby’. These source selections are found on the Generator – Audio Group 1,2,3,4 pages.
Selecting one channel of an audio pair to ‘Dolby’ will force the other channel in the pair to
select ‘Dolby’ also. As the Dolby streams are data, the volume and phase controls are disabled.
Changing a channel from Dolby to another source will cause the other channel in the pair to
select silence.

Frame Grab
Each Analyser module allows a video clip to be captured for analysis and playback. The video
clip contains the full SDI data frame including video data, metadata and audio data. The video
clip can be recorded manually or can be triggered by a number of different events such as
EDH and CRC errors. When Frame Grab record mode is selected a rolling record buffer (holding
approximately 70 SD frames or 13 HD frames) is started so that the full SDI data frames before
and after the trigger point are available for analysis. When a trigger is received the record
buffer is frozen to provide a video clip.
Once a video clip has been captured it can be played-back and navigated frame by frame using
the transport controls within the image are of the Picture instrument. The Rx instruments can
be used to analyse the SDI data frame by frame to display errors at the trigger point and the
status of the SDI frames before and after the trigger point.
The captured video clip can be saved for future reference and previously saved clips can be
restored.
To manually capture a video clip, select the record button to start the record buffer
(“RECORDING”) and then press the T button to stop the record buffer (“CAPTURED”).

mode, the data may be displayed in hexadecimal, decimal or binary formats. The binary format
is not available in grid mode. The data may also be displayed as 10-bit or 8-bit format.
Note that the line number of a line of video changes at the end of active video.
This gives the strange side effect that the line number for pixels in horizontal
blanking is the same as the line number for the active picture after that line.
Type
Grid: In this mode the data is shown in an X-Y format with lines and samples at the same
time. Thus this is a representation of the picture but in data format. If the cursor
keys are used to select the grid window and ‘OK’ pressed, the cursor keys will
scroll around the window. The luma (Y) channel is shown in white whilst the Cr and
Cb channels are shown in with a red or blue tint respectively.
Strm: This is one of 3 modes for displaying the samples on the current line only. The
cursor keys may be used to scroll the sample number when ‘OK’ has been
pressed. The ‘info’ column shows the type of data being displayed.
AP - Active picture
VBL - Vertical blanking
HBL - Horizontal blanking
Comp: This is a similar to the Strm mode above but in a component mode with Cr and Cb
in different columns. See Strm mode above for the info column description.
Split: This mode shows the 2 streams split into 4 parts to show Y, Y’, Cr and Cb in
separate columns. See Strm mode above for the info column description.
Note that when in Colour modes other than YCbCr 422 10 bit, the pixel RGB or
YCbCr values are packed into 10 bit values across the different streams and thus
will give unfamiliar values. When the ‘UnPack’ check box is checked the values in

Displaying Jitter
Eye
Overview
The Rx Instrument with an Analyzer Eye Module installed can display the selected input in the
form of an Eye Pattern. This allows the jitter of the selected input video signal to be monitored
using an Eye Pattern display.
Using the Rx 2000 front
panel, the Eye menu can be
displayed by selecting the
corresponding “Anayzer”
button.
The name Eye Pattern is given to the measurement of SDI clock jitter display that forms the
shape of an eye due to the 2 superimposed clock cycles. The ‘open eye’ is displayed when
monitoring a jitter free SDI signal and the eye closes increasingly with the severity of the jitter.
The Eye Pattern is formed by sampling the SDI signal at specific points in a progressive manner
and displaying each sample taken on a persistent screen until the waveform is complete.
Cause of Jitter
Jitter can be caused by a range of different things and the artefacts displayed in the Eye
waveform are typically due to combinations of these at different frequencies and amplitudes:
Transmission jitter caused by the equipment generating the video signal. This could
include clock phase jitter, amplitude jitter and wander.
Receiver phase lock loop errors in equipment decoding an SDI datastream. For example
when video sources are switched and the circuitry of the equipment need time to
establish phase lock or when the signal is distorted by long cable lengths.
Data dependent jitter due to the actual data content that, even after randomisation, that
contains sequences of zeros long enough for the clock regeneration to loose phase lock.
Thermal and Shot Noise caused by the integrated circuits used within equipment.
Integrated Circuits can contain 10s of thousands of discrete transistors that can all cause
random errors, increasing in number as the temperature of the equipment rises.
Electromagnetic interference in Long cable lengths that may be susceptible to
interference from the power grid and from power switching.
Distorted waveform shape, created by equipment, by long cable runs, by poorly
terminated, un-equalised cables, poor cable frequency response of or poor return-loss.

Page 65
Problems occur when these errors cause a level of jitter outside the specified acceptable
parameters. The different types of jitter are classified as follows:
Timing Jitter refers to a short-term time interval error above a low frequency threshold of
10 Hz (as defined in the SMPTE standards for SDI signals).
Alignment Jitter refers to artefacts above the specified threshold frequencies of (1 kHz for
SD-SDI signals and 100 kHz for HD-SDI signals). Typically video equipment
cannot tolerate Alignment Jitter which cause decoding errors due to
incorrect sampling of the data stream because the SDI Clock transition
occurs on the edge of the data sample instead of in the centre of the data
sample.
Wander refers to a long-term time interval error, ie artefacts below 10 Hz. Typically
all video equipment has the tendency to cause wander over a long period,
the display of these artefacts are not easily displayed in a meaningful way
but are better logged as errors that exceed tolerances over a long period.
Random Jitter refers to artefacts caused by random events or processes such as thermal or
shot noise that cause small amplitude variations in the clock edge position
or could cause large signal amplitude variations, though these typically
would be infrequent.
Note that if an Rx Generator modules is being used as the test pattern generator
then the System Reference should be set to Free Run to avoid the introduction of
jitter caused by the Rx locking circuitry.
Front Panel
Eye Display
The “Eye and Jitter” display shows the Eye Pattern against a vertical graticule of +500mV
to -500mV. Four horizontal cursor lines show the 100%, 80%, 20% and 0% measurement
positions on the waveform. Along the bottom of the display are continuous automatic
measurements for:
Amplitude – measured in mV
Rise time – measured in Pico seconds. The rise time measurement is specified as the
time between the 20% and 80% points on the eye waveform.
Fall time - measured in Pico seconds. The fall time measurement is specified as the time
between the 20% and 80% points on the eye waveform.
Rise/fall difference - measured in Pico seconds
Rising edge overshoot – measured as a percentage of the overall signal amplitude.
Falling edge overshoot – measured as a percentage of the overall signal amplitude.
Cable length – measured in Metres. The cable length display is only an approximate
value with 10m resolution thus a 5m cable will be shown as 0m long. The cable type
affects the length displayed which has been calibrated for Belden 1694A cables.
Any measurements which exceed the specification of the SDI signal are indicated in RED whilst
valid parameters are displayed in WHITE.
Note that if jitter values are too large, the automated measurements cannot be
made accurately and should NOT be relied on.
The eye display is only accurate when connected via a 1m cable, if a longer cable is used the
eye will begin to ‘close up’ and measurements will become harder to perform. Note that the
eye display is of the signal pre-equaliser, the equalizer in a system being used to compensate
for long cable lengths. There is no method for the Rx instrument to view the signal postequaliser.

Jitter Filters
The “Jitter 1” and “Jitter 2” filter options allow the specific type of jitter to be applied to the
waveform and the thermometers displays. The options are:
Timing as determined by the SMPTE standard for the specific video standard (ie jitter
above the 10 Hz threshold)
Align as determined by the SMPTE standard for the specific video standard (ie jitter
above 1 kHz threshold for SD-SDI signals and 100 kHz for HD-SDI signals)
10Hz jitter above a 10Hz threshold
100 Hz jitter above a 100Hz threshold
1KHz jitter above a 1KHz threshold
10KHz jitter above a 10KHz threshold
100KHz jitter above a 100KHz threshold
Jitter filter selection affects both the jitter thermometer and eye pattern displays. Timing
and Alignment jitter filters are defined in the relevant SMPTE publication. The thermometer
automatically calibrates to the specification of the video standard and chosen filter. When
reading is in specification the thermometer bar is GREEN, when close to specification it is
YELLOW, and when out of specification it’s RED.

Advanced Jitter Analysis (Option)
The Advanced Jitter
Analysis option provides
the user with additional
tools on the Eye display to
help determine the nature
of jitter present in SDI
signals.
Histogram: Amp/Timing/Both. Histograms enable the operator to observe the distribution
of samples in both amplitude (Amp) and time (Time). The amplitude histogram
shows the distribution of samples over the complete visible eye picture. The time
histogram shows the distribution of samples at the zero point of the eye waveform
for two thirds of the visible time period.
Note that he time histogram overlays some of the automatic measurement display.
The measurements may still be read by Remote Control if purchased.

Signal Information Menus
Overview
These pages give a detailed view of the status of the input (or generator output) signal. They
are sub-divided into Video, Misc, Audio and Ancillary (ANC) status.
Video Status
The Rx Instrument with an Analyzer Module installed can monitor the selected input and
display any EDH (error detection and handling) or CRC (cyclic redundancy check) errors
detected in the data stream.
Using the Rx2000 front
panel, the Video Status
menu can be displayed by
selecting the corresponding
“Sig Info” button.
Front Panel
Selecting SDI Errors will display the EDH or CRC status of the analyzer input as appropriate for
the video standard being monitored. The status of each EDH/ CRC count is displayed as the
number of seconds since an error occurred.
EDH/CRC ERRORS
This displays the EDH or CRC status of the analyzer input as appropriate for the video standard
being monitored. The status of each EDH/ CRC count is displayed as the number of seconds
since an error occurred. The individual CRC fields may be reset individually or together. The
‘running time’ field shows the time since the last error reset occurred. The error rate field shows
the number of errors per second. The running time will also be affected by the input being lost
or being intermittent. CRC errors are ignored on the switching line if the ‘Ignore switch line’
check box is checked.
ANC checksum errors are also detected and counted and may be logged.
When analysing a 3G-Level B signal, the CRC status is displayed for each link or stream present
according to the input video format. On an RX instrument with a Dual-Link module with 2 video
inputs, only one 3G-Level B may be analysed for CRC status at a time.
EDH DATA
If the signal is SD (PAL-625 or NTSC-525) the EDH values for both active picture (AP) and
full-field (FF) are displayed for each field. To enable engineers checking EDH integrity, the EDH
values calculated for active picture and full-field are also displayed.
Under normal conditions, the EDH-AP values should be constant, the full-field values may
change if audio or other ancillary data is embedded in the SDI signal.
Rx 2000 Operaon Manual 2–41PHRX2000-201 8
Page 70
Front Panel
The EDH flags for active picture, full-field and ancillary data are also displayed for diagnostic
purposes.
Edh: Error Detected Here - This is set to 1 if a SDI error was detected. In the case
of ancillary data, this means that one or more ANC data packets had an incorrect
checksum.
Eda: Error Detected Already - This is set to 1 if a SDI error was detected in the signal
received by the previous device.
Idh: Internal error Detected Here - This is set to 1 if a hardware error was detected in the
previous device.
Ida: Internal error Detected Already - This is set to 1 if an idh flag was received by the
previous device.
Ues: unknown error status: This is set to 1 if the previous device received an SDI signal
from a device not supporting EDH.
Note that there is only one EDH detector which is connected to the input currently being
analysed. On an Rx instrument with multiple video inputs, only the current input being
analysed can check for EDH errors.
Cable Length
The Rx instrument measures the cable length connected to the SDI input BNC and the
measurement is only an approximate value.
The cable type may be set to one of the following:
Belden 8282, 1694A, 1505, 1855A.
Canare L-5CFB
Image 1000
The selected cable type will affect the cable length measurement.
Active Picture CRC
16-bit CCITT CRCs are calculated for the active picture data of the received signal. This can be
used to give a known value for known static picture content and allows the user to determine if
the active picture content is as expected.
CRCs are calculated independently upon each 10-bit stream (luminance and chrominance) of
the interface.
For example the generated 1920x1080, 100% bars in YCC422-10 should always produce a
luminance CRC of 0x0AB4 and a chrominance CRC of 0xB88E, no matter what scanning mode
(interlaced, segmented frame or progressive) or frame rate is used.
Note: when using 4:4:4, 4:4:4:4 or 12-bit video formats (in dual-link or 3Gbps)
the CRCs are calculated for each of the packed 10-bit virtual interfaces and will
therefore generate different values from those for YCC422-10.
See the “Active Picture CRC Technical Information” section at the end of the manual for details
of CRC calculation.

MISC Status
The Rx Instrument with an Analyzer Module installed can monitor the selected input and
display the content of any SMPTE 352 packets detected in the data stream.
Using the Rx2000 front
panel, the Misc Status
menu can be displayed by
selecting the corresponding
“Sig Info” button.
Payload ID – SMPTE 352
If the Rx instrument has detected a SMPTE 352 ancillary packet, it will be displayed here in
hex and decoded format.
Front Panel
The display shows the transport media, frame rate and interlaced/progressive/segmented frame
mode, as well as colour format, bit depth, dynamic range and channel number. See the SMPTE
352 specification for further details.
When analysing a 3G-Level B signal, the SMPTE 352 status is displayed for each link or stream
present according to the input video format. On an RX instrument with Dual-Link with 2 video
inputs, only one 3G-Level B may be analysed for 352 status at a time.
Video Format
This displays the currently detected line length for both active video and full line including
blanking as well as the number of active lines for the inputs present.
Note that the video frequency displayed is only correct if the Rx instrument has
been calibrated and free running or has been connected to an accurate reference
input.
If the input signal is not a known signal (i.e. the line count or pixel count is not recognised) The
input status on the top line will show “Invalid” but the values in this section will be updated
every few seconds.
The Re-sync counter displays the number of times the SDI data has been re-synchronised and
can help detect intermittent SDI signal problems.

Video Timing
The Rx Instrument with an Analyzer Module installed can monitor the selected input and
display its timing relationship with the locking reference.
Using the Rx 2000 front
panel, the Video Timing
menu can be displayed by
selecting the corresponding
“Sig Info” button.
The timing of SDI input signals is displayed relative to the external reference. If no reference is
present then an error message is displayed. If the signal is timed to within +/- 2 samples the
values are displayed in black in lines and samples (spl) If mistimed, then they will be displayed
in red. A bar graph also displays the timing value which may either be line timing (+/- 0.1 lines
or +/- 0.5 lines) or frame timing (+/- 0.5 frame). The total timing value is also displayed in
micro seconds.
The RED arrow on the bar shows the SDI input timing and the BLUE arrow shows the current
target timing point. The BROWN line shows the timing of the reference signal.
To compare timings of different signals, connect the signal to be compared to the SDI input and
select the “Offset” button to make this the current offset. All future timings will be relative to
this offset value.
To clear the current offset, move the focus to the 2 offset fields, press OK to edit them and then
press default.
Note that all timing measurements are relative to line 1 on the SDI signal and
line 1 on the reference signal. This can lead to different values to other test
and measurement instruments that include an SD (PAL/NTSC) offset in their
calculations. By comparing line 1 timings, the Rx instrument can be used to
accurately measure time delays through up/down/cross converters.

ANC Status (SDI Analysis Option)
The Rx Instrument with an Analyzer Module installed and SDI analysis option can monitor the
selected input and display details of any Ancillary packets within the SDI data stream.
Using the Rx 2000 front
panel, the ANC Status
menu can be displayed by
selecting the corresponding
“Sig Info” button.
The ANC status menu shows which ANC packets are present on the SDI input and whether they
have any errors.
Each field is colour coded according to whether the ANC packet is present (White), missing
(Grey), has errors (Red), or has previously had errors (yellow).
Front Panel
If the field has errors then a symbol beside the field shows which error type it is. The bottom of
the page shows the symbol for each type of error. The Reset button resets the “Previous Errors”

The Setup button and dialog allows user defined ANC
packets to be configured.
The packet name, data ID (DID) and SDID may be specified for up to 3 user-defined ancillary
packets. The stream field specifies whether the packet should be on the chroma stream, the
luminance stream or both.

ANC Inspector (SDI Analysis Option)
The Rx Instrument with an Analyzer Module installed and SDI analysis option can monitor the
selected input and display the contents of selected Ancillary packets within the SDI data.
Using the Rx2000 front
panel, the ANC Inspector
menu can be displayed by
selecting the corresponding
“Sig Info” button.
The packet type can be selected using either the drop down list of known packets or the DID/
SDID (Data Identifier/ Secondary Data Identifier) number fields (for example RP165 – EDH,
S272 – SD Audio Group 1, S272 – SD Audio Group 2, etc). If the DID/SDID values match a
known type, then that type will be selected in the drop down list. This may be further filtered
using the Check Boxes on the Setup dialogue.
Note that the settings of the Setup dialogue affect the currently displayed data. For example if
any trigger parameters (such as DID or SubDID set to specific values that don’t actually appear
in the data) are set this may prevent data being displayed.
When searching for specific data events it is advisable to turn off the Trigger parameters such
as “DID”, “SubDID”, “Checksum”, “DBN” (Data Block Number), “Parity” and “ANC Gaps” first
to ensure that you are actually seeing data for the selected ANC packet. Only when the ANC
Inspector is displaying streaming data, should you introduce the specific trigger parameters
required to trap the data packet that you are looking for.
The Line and sample number of the detected packet is displayed to facilitate debugging of
generation equipment. The complete data packet is displayed as a hexadecimal grid at the
bottom of the page and may also be decoded into text above the grid.
If an error occurs in the packet, the header and checksum are displayed in red.
The display of data may be frozen by pressing the Freeze check box.
The ‘Found’ description shows in which stream the ANC packet was detected, Chroma or Luma
and what kind of trigger was detected. This may be:
C Checksum Error
D DBN (Data block number) Error
P Parity Error
G ANC Gap error
Several of the above flags may be displayed at the same time.
The ANC packets detected may be filtered using the Setup dialogue. This allows a great deal of
freedom in setting when the display will be triggered.
If the On Trigger check box is checked the data packet will cause the display to be frozen and
the Freeze check box will turn red when a trigger condition is met. See the section on the ANC
Inspector setup dialogue below. Un-checking the freeze button will restore normal operation.
The “->Cursor” button will copy the Line and Sample numbers to the SDI data view cursors to
simplify navigation to the ANC packet under investigation.

Parity: A parity error was detected for the DID, SDID and DataCount words in a packet.
(Even Parity used and bit 9 is inverse of bit 8)
ANC Gaps The ANC packets were separated by a gap containing video blanking data.
EDH (DID=0xf4) packets are ignored. Note that if an EDH packet is marked for
deletion, this will result in an ANC GAP error.
The Setup dialogue also shows when an ANC packet has been detected and where it was
found. This makes changing a filter simpler as the effect of the filter can be determined without
closing the dialogue.
This dialogue also allows the user defined ANC packets to be configured.

Dolby Status (Dolby Analyzer Option)
The Rx Instrument with an Analyzer Module installed and Dolby Analyzer Option can monitor
the selected input audio and provide details of its Dolby E audio encoding.
Using the Rx2000 front
panel, the Dolby menu can
be displayed by selecting
the corresponding “Audio”
button.
The Dolby E status option allows display of the Dolby E metadata present in the selected audio
stream and determines whether the Dolby E packet is timed correctly on the SDI video stream.
This option therefore allows the correct timing of the Dolby E packets with the SDI signal to be
checked at all stages in a broadcast chain.
Checks can be made to see that the Dolby E has been created correctly and transferred
transparently through the broadcast chain unaffected by routers/switchers, satellite links, etc.
Overview
Dolby E, Dolby Digital and Dolby Digital Plus digital audio standards can be transported as
audio data over an SMPTE 337M AES carrier with a 48kHz sample rate.
These standards can be used to transport mono, stereo, 5.1 and 7.1 audio programmes:
Dolby 5.1 - involves five channels for normal-range speakers (20 Hz – 20,000 Hz) (right
front, centre, left front, rear right, rear left) and one channel (20 Hz – 120 Hz allotted
audio) for the subwoofer driven low-frequency effects.
Dolby 7.1 uses six channels in the primary program (Independent Substream) for a
standard 5.1 surround sound mix and then the 2 remaining 2 channels in an ancillary
programme (Dependent Substream) to provide the additional down-mix.
Dolby E
Dolby E is an audio encoding and decoding technology developed by Dolby Laboratories that
allows up to 8 channels of audio (mono, stereo, 5.1 or 7.1) that for a primary programme
(Programme 1) and optional ancillary programs. These 8 channels are compressed (loss-less)
into a digital stream that can be transferred between compatible devices and stored on a
standard stereo pair of audio tracks.
Dolby Digital
Dolby Digital (AC-3) is a ‘perceptual audio’ system for digital audio that allows the reduction
of data needs to deliver high-quality sound. This system was developed primarily for DTV, DVD
and HDTV. This format allow up to six channels of sound (mono, stereo or 5.1) in the form of a
single ‘program’ that can be delivered at different bit rates. These 6 channels are compressed
(lossy) into a digital stream that can be broadcast. The most elaborate mode in common use is
Dolby 5.1 with uses all six channels to provide surround sound.

Dolby Digital Plus (E-AC-3) is a more advanced version of Dolby Digital that provides a more
efficient encoding algorithm that provide enough bandwidth that allows up to 20 channels of
audio (mono, stereo, 5.1, 7.1 up to 13.1) that for a primary programme (Programme 1) and
optional ancillary programs that can be delivered at much lower bit rates than Dolby Digital.
These 20 channels are compressed (lossy) into an independent digital data stream plus up to
8 dependent sub stream that can be transferred between compatible devices and stored on a
standard stereo pair of audio tracks.
Analyser Reference
In order for the Dolby E data to be decoded correctly, the internal audio circuitry requires a
reference that is synchronized to the input SDI signal for embedded audio and the external
system reference for AES audio. The Generator Reference MUST NOT be set to Free-Run or
Dolby errors may be detected. Note that the description field will display “Invalid Reference” if
an incorrect reference is selected.
In this example, the SDI signal contains
embedded audio with Dolby E, Dolby
Digital or Dolby Digital Plus present on one
or more audio pairs. The Rx instrument
needs to lock its internal audio clock to
the SDI signal and the Rx needs to be
configured to select the specific audio
channels containing the Dolby audio
Front Panel
In the example below, the AES signal contains a Dolby digital audio stream. The Rx instrument
needs to lock its internal audio clock to the external reference signal. This can be done
from the “Ref” menu on the HDMI task bar, the Rx2000 “Dolby Metadata” and the Rx2000
“Generator” - “Genlock” menus.
In the Dolby Meta-Data window, the Dolby Timing source should be set to Ext Ref.
The AES source MUST be locked to the same reference as the Rx.
Source selection
The Dolby E may be monitored from any of the SDI input embedded audio channel pairs or the
AES input. The two drop down lists in this section allow the module input and specific audio
channels to be selected.
Dolby E Framing Values
It is important for the Dolby E packet to be positioned well away from the video switching line
so that Dolby E packets are not corrupted by downstream switchers. At all places in the signal
Rx 2000 Operaon Manual 2–55PHRX2000-201 8
Page 84
Front Panel
chain where audio can be delayed by a different value to the video, the Dolby E packet needs
to be re-timed to make sure that this timing specification is met. The position of the Dolby E
packet in the video frame is displayed in lines and micro-seconds (us).
Dolby E Timing source
Dolby E timing may be measured relative to the SDI input or the External reference. If the
‘Ideal’ check box is checked, the Dolby E Frame timing is relative to the normal position that it
should be, ie it should be as close to 0 as possible. Each video standard has a specified ‘Ideal’
line number that the Dolby E packet should start on. If the Dolby E timing line is outside the
valid range of lines it will be displayed in red. If it is outside the ideal range it will be displayed
in dark green – this is still a valid Dolby E position but not recommended by Dolby. The timing
measurement is always displayed in terms of the SDI input lines and thus if an AES input is
used as the Dolby E source, the line position will NOT be displayed.
If you do not have the same reference as the SDI source, you will have to set the Reference
Source and Dolby Timing Source to be the SDI input.
IMPORTANT: If Dolby E is present on a fast frame rate signal (50p, 59p or 60p) then it should
always be referenced to a interlaced reference at the same field rate as the packet length is
longer than a single frame and must start at the beginning of an even numbered frame.

output.
Org Stream the Original Bitstream informational parameter sets the value of a single bit
within the Dolby Digital bitstream. This bit has a value of 1 (box checked)
if the bitstream is an original. If it is a copy of an original bitstream, it has a
value of 0.
Copyright the Copyright Bit informational parameter sets the value of a single bit
within the Dolby Digital bitstream. If this bit has a value of 1 (box checked),
the information in the bitstream is indicated as protected by copyright. If it
has a value of 0, it is not copyright protected.
RF 0v Prot the RF Over-modulation Protection parameter determines whether or not
an RF pre-emphasis filter is used in the overload protection algorithm to
prevent RF over-modulation in set-top box decoders.
Peak Metering
The peak audio levels are included in the Dolby E metadata packet and may be displayed on
the Audio - Meters page. Select the appropriate set of meters to display Dolby levels and then
they will follow the selected Dolby E source.
Note that audio cannot be decoded by the Rx range of products and so you will
NOT be able to listen to the Dolby E signal. Note also that the LFE channel audio
levels do not seem to be metered by current Dolby encoding modules.

Loudness Meters
The tools provided in the “Loudness” window allow the loudness of the selected source stereo
audio pair, 5.1 surround sound audio group or decoded Dolby program (from the Dolby
Decoder module) to be monitored and measured. The Rx system provides a single Loudness
meter as standard and an additional 3 Loudness meters are available as an option.
Loudness is measured in
accordance with ITU 1770
and EBU Recommendation
128 which define the
measurement in terms
of Loudness Units (UI),
Loudness Units Full
Scale (LUFS), Loudness
K-weighted Full Scale
(LKFS) over different time
periods.
The Loudness display allows the required mode (Integrated, Momentary or Short Term), input
(SDI, Fibre or AES), audio source, and (in the case of a Dolby Decoder audio source,) Dolby
program to be selected.
Front Panel
The left hand part of the window displays the actual audio values of the select audio channels
numerically and graphically. The right hand part of the window provides the current Integrated,
Momentary and Short Term loudness values, a loudness bar graphically displaying the selected
loudness mode value, input and source selection and loudness logging controls.
The right hand part of the window also provides a True Peak Hold indicator showing the highest
perceived loudness level measured. The value will be displayed in red if it exceeds the True
Peak Alarm threshold level shown. The Alarm level is configurable in “Options”. The True Peak
Hold indicator can be reset.
Loudness Logging
If the “Enable” check box is selected in the “Logging” section, the system will log loudness
continuously and save CSV files every 30 minutes.
As defined in the EBU Recommendation 128, the loudness meter provides the following
functions:
Start - starts the integrated loudness measurement.
Pause - pauses the current integrated loudness logging process. Re-selecting this button
will resume the loudness logging process from the point where it was paused.
Reset clears the current Infinitely integrated loudness session.
Loudness logs are stored automatically each time the pre-set duration is reached. The duration
can be defined in the “Export Time” setting found in “Options”, to be between 1 minute and
3 hours long; although 30 minute intervals are more practical. These logs will be individual,
time-stamped CSV (comma separated value) files which are held in the “loudness” folder within
the Rx operating system (See the “Rx File Structure” section in the “Maintenance” chapter for
details).
Log files can be saved manually at any time by selecting the “Save” button in the “Loudness
Options” window; which can be accessed by selecting the “Options” button. Selecting the
“Save Name” text box will bring-up an on-screen keyboard to allow the CSV file to be named
appropriately. These logs can be copied onto a USB pen drive if it inserted in to the front panel
and selected using from the loudness folder.

Mode
The loudness is measured simultaneously with three different time periods:
M (momentary) covering the shortest timescale of 400ms
S (short term) covering the intermediate timescale of 3 seconds
I (integrated) covering the duration of a program or segment
The M, S and I values are displayed for the selected audio pair or 5.1 surround sound audio
channels.
Input and Source
The SDI input with the embedded audio channels to be monitored is selected using the “Input”
drop-down list. The audio channels within the selected input are then selectable from the
“Source” drop-down list. The loudness meter can display and log the loudness of stereo pairs
(for example “G1-P1”) or 5.1 surround sound audio channels.
Options
The Options menu allows
the selection of meter
scale (LU, LUFS or LKFS),
measurement standard
(EBU or ITU) and Meter
Range as well as userdefined threshold values
for Integrated, Momentary
and Short Term loudness.
This menu also allows
the manual or automatic
deletion of Loudness logs
The mode drop down allows the selection of the displayed scale of LU (Loudness Unit), LUFS
(Loudness Unit Full Scale) or LKFS (Loudness K-weighted Full Scale). These affect the loudness
values measured. Note that LUFS and LKFS have a -23 dB weighting to standardise broadcast
loudness measurement and prevent digital clipping. So if a -23 dB test tone is measured it will
give 0 LUFS or 0 LKFS.
The Standard drop down menu allows the EBU RP128 or ITU 1770 loudness measurement
standard to be selected. These affect the loudness values measured.
The Audio and dBFS drop downs in the Scales section allows the scales of the audio channel
meters to be selected. The actual scale of the Loudness meter is defined by the loudness mode
selection.
The “Integrated” (Infinity), “Momentary” and “Short Term” target values define the level, above
which, a loudness error is logged as exceeding the defined upper limits. The errors count
is displayed on the Loudness window. If Targets - Enable is selected in the “Local Options”
section, cursors will be displayed on the meter bar and the loudness values will flash red when
the target level is exceed. The dB values next to the “Integrated” (Infinity), “Momentary” and
“Short Term” values allow a guard band to be set above the target value.
In the “True Peak” section, the True Peak Alarm threshold can be set.
Selecting the OK button will save the current changes and the Cancel button will discard any
changes made.
Loudness logs that have been manually or automatically saved can be deleted manually using
the Delete and Delete all buttons. When continuously logging program loudness, the Auto
2–60 PHRX2000-201 8Front Panel 07/17

Delete function can be used to delete log files older than 1 to 10 days. To narrow down the
search when looking for existing log files, enable the Filter check box and then enter file name
text in the Filter text box.
Confidence Check
These different measure modes can give unpredictable results dependent on the type of
program and the combination of narrative, music and loud audio events such as explosions.
The actual values measured are also affected by the meter scale.
As a simple confidence check, use a stereo sine wave, 1000 Hz, -23.0 dBFS (per-channel
peak level), in phase as the test tone applied to both channels simultaneously for 20 second
duration. This should give the following results:
M, S, I = -23.0 ±0.1 LUFS or M, S, I = 0.0 ±0.1 LU

an IP Address from any network it is connected to. This will only work if there is a DHCP server
on network.
If your network has ‘static’ (non changing) addresses, you will need to see your network
administrator to get an address assigned to your instrument and to get the Subnet mask and
default gateway address. These details can then be entered in the corresponding boxes in the
menu. Select each numeric box in turn and use the up and down cursors to pick the required
value.
When the IP Address, Subnet Mask, Default Gateway and DNS Server values have been setup,
use the Apply button to attach the Rx instrument to the network.
On the Rx2000 instrument, select the “System” - “Network” menu to access the IP Address,
Subnet Mask, Default Gateway and DNS Server values. Select the “Setup” button and edit
the settings. Note that if the DHCP check box is enabled, you will not be able to change these
values. Once the network addressing has been setup, select the “Apply” button to attach the
Rx instrument to the network.

Remote Control of Rx Instrument
To allow remote control of an Rx instrument, you must have the TCP/IP address of the
instrument set and the Remote Control ‘On’ check box must be checked.
The list box shows a list of current connections made to the instrument. This includes the web
browser connection (127.0.0.1) which may be seen intermittently as the web browser connects
every few seconds and then disconnects again. See the remote control documentation
available for download for more information on the protocol and method of control.
The Rx instrument uses a default Port Number of 2100 for remote control access (See Remote
Control SDK documentation on Download section of PHABRIX Web Site) This port number may
now be changed if it conflicts with other applications in your system.
