Sx Software Options
Overview
The instrument has a range of software options that can enhance its functionality for specific
applications.
AV Delay Analysis (Option:PHSXO-AVD)
The AV Delay Analysis option (PHSXO-AVD) offers an end-to-end solution for the measurement of
the Audio to Video differential delay through a broadcast system, when used in conjunction with the
AV Delay Generator. The analyzer tool provides a real-time update of the differential delay between
the video and the selected audio channel pair. When using the SxA and SxE, this tool can also be
used to measure the propagation or pipeline delay of either video or audio.
Both the AV Delay signal generator and analyzer can be used with all Sx supported video formats
and frame rates on SDI interfaces.
The AV Delay Generator produces an adapted EBU Tech 3305 AV Sync
This is compatible with third party AV delay analyzers such as the LAWO V_pro8.
An audio delay offset with respect to video of up to +/− 40 frames can be applied in increments of one
frame.
The AV Delay audio pulse can be inserted on up to 16 embedded SDI audio channels.

AV Delay measurement (PHSXO-AVD) is available in the Picture instrument. Measurement of two AV
Delay test patterns is supported:
l
EBU Tech 3305
l
LAWO V_line AV Sync test pattern
The tool provides a real-time update of the differential delay between the video and the selected
audio channel pair.
The source of the audio is an embedded SDI audio pair.
Command Scripts with Print Report (Option:PHSXOS)
The Command Script and Reports option (PHSXOS) allows a series of predefined actions to be run
through within the PHABRIX Sx using a script stored in internal memory.
The command scripts option can be used to automatically step through a sequence of instrument
states, controlling the generator, analyzer and logging functions. If required, the instrument will
prompt the user before going onto a subsequent state.
Applications include repeated test sequences as required by manufacturer Test Departments,
Research and Development Departments, Systems Integrators and Commissioning/Support
Engineers.
A script requires a set of memories to configure the unit and then a script file which recalls those
memories and specifies times and actions for each step. The process of creating a command script
requires these two files to activate the sequence.
Additionally, a script can be created as a simple text file on a PC and then transferred to the unit over
the network and recalled at any time. Many named scripts and memories may coexist in the
instruments store to be recalled as required.
Access to the Command Scripts functionality is the menu:System → Command Scripts. See the
chapter
Menu Reference
for details.

Enhanced Remote Control (Option:PHSXOR)
The Enhanced Remote Control Integration option (PHSXOR) gives users full remote control of the unit
through 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.
PHABRIX products 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 Sx range can provide a variety of information to the
control device to which it is connected 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
will be configured accordingly and a reply returned and if you GET a value from the unit, it will reply
with that value. All messages are acknowledged to increase the security of the interface i.e., using
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 PHABRIX unit synchronizes with the host PC. Any changes on the PHABRIX
unit will result in a message being sent to the host PC. This method is useful for controlling a PHABRIX
unit from another unit or via the PC simulator software. It requires more complex software on the host
to respond to the returned messages.

Programmable Zone Plate (Option: PHSXOZ)
The Zone Plate Generator option (PHSXOZ) adds a range of preprogrammed zone plate patterns
along with user-defined controls over several parameters which can be saved to custom buffers.
Using the System → Memories menu window, multiple saves of zone plates can be saved to the
system by checking the video box and saving by name. In use, the zone plate can be used to test a
range of video processing requirements using horizontal, vertical and temporal (time) controls.
Temporal control is particularly useful for testing up/down converters and applications which
compress signals.
Aspect ratios can be tested using the horizontal and vertical controls. Frequency sweep is particularly
useful and also available using this option. By feeding in the generated signal, the output of the
device can be sent back into the waveform monitor of the Sx instrument to determine the usable
bandwidth of the system. Once purchased, the zone plate editor is accessed by selecting the button
next to the standard zone plate.
Dolby Bit-stream Analyzer and Generator (Option:PHSXO-DAG)
The Dolby bit-stream analysis and generation option (PHSXO-DAG) displays Dolby E, Dolby Digital
and Dolby Digital Plus metadata present in a selected audio stream and determines whether the
Dolby E packet is timed correctly on the SDI video stream. It also uniquely adds significant Dolby E,
Dolby Digital, and Dolby Digital Plus metadata generation features to the Sx range.
The Dolby audio may be monitored from any of the SDI input embedded audio channel pairs. Peak
audio levels are also displayed for Dolby E.
PHABRIX SxD
User Manual Page 1-9
Page 19
The start menu window displays both the V Bit information and PCM values along with a snapshot of
the Dolby audio metadata if a Dolby is present. Using the Signal Information - Dolby menu will present
the full analysis display which forms the major analytical tool for this option.
The Dolby metadata screen carries primary information including signal source, Dolby E
guard band
timing, CRC errors, program channel and metadata detail. The characters shown in white will only be
presented when a Dolby signal is introduced into the unit.
Peak audio levels included in the Dolby E metadata packet are displayed, allowing the user to select
the appropriate set of meters to display Dolby levels which will follow the selected Dolby source.
Logging for Dolby errors, Dolby E Timing, Common metadata, and Program metadata can also be
controlled.
Note: This option does not decode Dolby audio
The Dolby generation capability provides broadcast engineers with a highly functional set of tools for
Dolby E, Dolby Digital and Dolby Digital Plus streaming. It is unique in being the world’s first metadata
Dolby generator with editable profiles.
With a selection of Dolby streams to choose from, engineers can quickly enter and adjust parameters
to check broadcast infrastructure.
This option allows the display of Dolby metadata present in a selected audio stream and determines
whether the Dolby E packet is timed correctly on the SDI video stream.
Dolby streams are provided for all program configurations with fixed audio data. Among the tools
included in the Dolby E streaming option is the ability to adjust the
start of frame
for Dolby E packets.
The generated Dolby audio follows the video generator reference source. There is also the ability to
edit the program configuration and bit depth with fixed audio signal. The PCM stream can be carried
on any embedded pair. The option can set the video line number where the internally generated
Dolby audio test stream begins. Metadata can be edited by the user and stored in memories.
The option allows a closed loop test scenario with both generation and analysis toolsets.
Note: This option does not generate Dolby audio.

Ancillary Data Status (Now Included as Standard)
The Ancillary Status option (PHSXOVNC) provides broadcasters, studios, OB and broadcast
manufacturers with a detailed analysis of the ancillary data present in an SDI signal.
A simple grid layout provides a quick check for an engineer of the available VANC/ANC ancillary
data. The packet type is then displayed as present, absent or red if in error. Simple icons next to the
packet indicate the fault. Each ancillary packet available from the grid view can be set to enable
logging and then presented together with other information in the events window of the logging
menu.
This option further allows additional, user-defined selections with the appropriate DID or SDID code.
Any ancillary packet code can be saved down for future recall. Note that this option does not fully
decode the ancillary data, but instead it is used to identify whether the packet is present in the signal.

2K-SDI Support
The SxD supports the generation and analysis of 2K video formats for YCbCr, RGB and XYZ color
spaces as standard.
XYZ Color Space:
A non-linear format that requires additional treatment by the Sx generator and analyzer circuitry to convert between linear and non-linear data formats. Only a limited number of nonlinear test patterns are provided for XYZ as the traditional linear test patterns that are usually available in SD, HD and 3G are not applicable and will produce misleading results
when analyzed.
100% Color Bars:
Generated in RGB color space and needs to be analyzed using the RGB color space selection in the Waveform monitor. This test pattern is provided to check the accuracy of the
color paths through the equipment under test.
Legal Ramp:
Generated in XYZ non-linear format and needs to be analyzed using the X'Y'Z' color space
selection in the Waveform monitor. This test pattern is provided to check the accuracy of
the data path through the equipment under test.
Multiburst:
Generated in XYZ non-linear format and needs to be analyzed using the X'Y'Z' color space
selection in the Waveform monitor. This test pattern is provided to check the frequency
response and sample rate of the data passed through the equipment under test.
Color Field:
Produces fixed level colors in RGB color space that are converted to equivalent XYZ color
space values and needs to be analyzed using the RGB color space selection in the Waveform monitor.
User File:

Allows user-defined test patterns that have been created in XYX non-linear color space to
be selected.
The XYZ, X, Y and Z settings in the Waveform monitor display the XYZ color space in its native nonlinear form. So test patterns such as Legal Ramp will be displayed as curves instead of straight lines.
The X'Y'Z', X', Y', and Z' settings in the waveform monitor display the XYZ color space with a reverse
transform to convert it to linear form, so test patterns such as Legal Ramp will be displayed as straight
lines.
The Picture monitor and Vectorscope instruments will automatically apply the appropriate transforms
to display the images in YCbCr, RGB and XYZ color spaces correctly. The color space transform to be
applied is defined by the SMPTE 352 payload.

AV Delay:
The AV Delay Test pattern and associated audio pulse provided by the Generator module
can be used to check the differential delay between video and audio. This animated test
pattern provides a constantly moving clapperboard and the corresponding AV Delay
Audio pulse and video white line flash when the clapperboard reaches the center of the
test pattern.
Color Field:
If color field is the selected test pattern, another control selects which color to generate.
Three user definable custom colors may be defined using the -> button. Custom colors are
edited using the Red-Green-Blue sliders. When setting the color using the RGB sliders, the
YCbCr values will show the values for the current color space. When setting the color

AV Delay Generator
The AV Delay Generator produces an adapted EBU Tech 3305 AV Sync
clapperboard
Test Pattern.
An audio delay offset with respect to video of up to +/− 40 frames can be applied in increments of one
frame.
The AV Delay test pattern and audio pulse provided by the Generator module can be used to
measure the differential delay between the video and audio paths in a piece of equipment or an SDI
based system.
In the Video Out menu page, the AV Delay test pattern and Audio Delay offset can be selected.
In the Audio Group menu pages, the AV delay audio pulse can be inserted on up to 16 embedded
SDI audio channels.
Note: The AV Delay signal is compatible with third party AV delay analyzers such as the LAWO
V_pro8.
The AV Delay Generator creates an adapted EBU Tech 3305 AV Sync pattern. This provides a
constantly moving
clapperboard
which, when it closes, shows a vertical white
flash
line for one frame
with a corresponding audio pulse.
To access the AV Delay Generator option:
l
Select A/V Delay in the Pattern dropdown menu
AV Delay can be used with all Sx supported video formats and frame rates on SDI interfaces.
An Audio Delay field is then displayed.
Note: The SxD is restricted to SDI as it has no dedicated AES interfaces.
Using the Audio Delay field, you can offset the timing of the generated audio pulse relative to the
central white flash frame of the test pattern. An audio delay offset of up to +/− 40 frames can be
applied in increments of one frame. The delay value in milliseconds is displayed alongside the frame
delay value.
l
When Audio Delay is set to a positive (+) value, the audio pulse will lag the video
l
When Audio Delay is set to a negative (−) value, the audio pulse will be ahead of the video.
The audio delay offset has several applications:
PHABRIX SxD
User Manual Page 2-7
Page 28
1. The differential delay of a system or device under test can be quickly measured in TV frames
by adjusting the Audio Delay offset until the measurement reads less than a TV Frame. This can
quickly confirm that the differential AV delay is an integer number of TV frames
2. The analyzer can measure AV differential delay up to +/− 400 ms. If the system under test has a
propagation delay longer than this, setting an offset of up to −40 frames extends the overall
measurement window.
On the AV Delay analyzer, a measured delay amount that is not accounted for by the generated
Audio Delay offset, will indicate delay introduced by the system under test.
To choose the AV Delay pulse audio channels, go to the Generator → Audio Group [1/2] [3/4] menu
pages, and select AV Delay in the dropdown menu for each audio channel as required.
EDH
If the output signal is SD (PAL-625 or NTSC-525) the insertion of EDH information may be switched 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 is deliberately corrupted, creating one error count per field or, more
precisely, one AP error and one FF error. In HD, a CRC value is calculated for each line. When errors
are being inserted the CRC value on line number 1 is 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 checkbox allows the SMPTE 352 Payload ID field to be inserted into the video output stream.
The state of this checkbox is stored separately for SD, HD and HD-3G line standards.
Note: For all HD-3G line standards the Payload ID should be switched on.

Genlock Menu
The Sx instrument 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.
Source
The generator may be locked to an input reference which may be either the external reference input
which is a Bi-Level/Tri-Level sync or may be locked to the video input (Input-1). Alternatively, the
generator may free-run.
If Free-Run is selected, the user can select the Adj Freq checkbox to adjust the frequency of the
datastream by more than + / − 100 ppm. This feature enables the user to generate SDI signals that are
off-frequency to, for example, test the susceptibility of a system to absolute clock frequency. The
adjustable range is from 0 to 1024, with the nominal mid-point at approximately 580. Incrementing the
value increases the signal frequency and decrementing value decreases the frequency.
Frequency Adjustment Offset
0 (Min) −580
580 (Default) 0
1024 (Max) + 444
For example, a signal of 2.97 GHz can be adjusted with an offset between 2.969420 GHz and
2.970444 GHz.

Source
The source for each channel may be Silence, Fixed tone (a range of fixed frequencies), variable tone
(where the frequency can be set on 1 Hz steps from 1 Hz to 23.99 kHz), white noise, or AV Delay. If the
Dolby Generation option has been purchased, the source may be set to Dolby at which time the
other channel in the audio pair is also set to Dolby and gain control is disabled.
AV Delay Audio Pulse
For AV Delay audio pulse generation, choose which audio channel should carry the AV Delay pulse,
and then set the source to AV Delay in the dropdown menu. Make sure that the Group checkbox for
this channel is also enabled.
The AV delay audio pulse can be inserted on up to 16 embedded SDI audio channels.
If an Audio Delay offset is required for the generated AV Delay pulse, this can be set in the Generator
→ Video Out page after selecting the A/V Delay test pattern. An offset of up to +/− 40 frames can be
applied in increments of one frame.
Inv (Invert)
This checkbox phase-inverts the audio signal to allow checking of third-party audio mixing.
Link
This checkbox links the left and right channels of a pair so that changing the level on the left-hand
channel also changes the level on the right-hand channel.
Master
The Master level sets the 0 dB level for all the embedded audio channels, so if the Master level is set
to −18 dB and Group 1 Pair 1 output is set to −2 dB, the actual level output on that pair is −20 dB. This
feature allows all embedded outputs to be adjusted together, as well as giving a simple method to
change from −18 dB to −20 dB based standard levels.

Dolby (Dolby Generator Option: PHSXO-DAG)
The Sx instrument Dolby Generator software option (PHSXO-DAG) allows the 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.
The Audio - Dolby menu controls the generation of Dolby test data.
Note: Note that with this software version non-keyed signals are generated which may be
incompatible with certain VTRs.
Overview
There are several Dolby broadcast digital audio standards that transport audio data over an SMPTE
337M AES carrier with a 48 kHz sample rate. The type of Dolby to be generated can be selected from
the dropdown list in the top left corner of the menu:
l
Dolby E
l
Dolby Digital
l
Dolby Digital Plus
These standards can be used to transport mono, stereo, 5.1 and 7.1 audio programs:
Dolby 5.1:
Involves five channels for normal-range speakers (20 Hz – 20,000 Hz) (right front, center,
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 remaining two channels in an ancillary program (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) for a primary program (Program 1) and optional
ancillary programs. These eight channels are compressed (lossless) into a digital stream that can be
PHABRIX SxD
User Manual Page 2-13
Page 34
transferred between compatible devices and stored on a standard stereo pair of audio tracks. The
most elaborate mode in common use is Dolby 7.1 which uses all eight channels to provide surround
sound.
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 allows 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 six channels are compressed (lossy) into a digital
stream that can be broadcast. The most elaborate mode in common use is Dolby 5.1 which 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 offering a primary program and optional ancillary programs. These can be
optionally delivered at lower bit rates than Dolby Digital.
Dolby E Synchronization - Generator Reference
The Dolby audio test signal produced by the Sx instrument is affected by a reference signal
connected to the Sx instrument and by the following settings:
Free Run:
If the generator is not locked to reference, the Dolby signal will be generated synchronous
to the generator. If the generator is running at a fast progressive rate (50 - 60 fps) it will generate packets on every other frame.
External Reference / Ext SDI Reference:
If the generator is locked to an external signal, the reference signal
priate standard. See the table below for examples.

Editing Program Information
Stream type:
Only Dolby E streams can be generated with this software version.
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 −3 dB co-phased/timed and are at the same frequency.
−18dB Fixed:
All the tones are at −3 dB co-phased/timed and are at the same frequency.
−20dB Fixed:
All the tones are at −3 dB 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 4.8 kHz 211 Hz
24 6 kHz 240 Hz
25 / 50 6 kHz 240 Hz
29.97 / 59.84 6 kHz 133 Hz
30 / 60 6 kHz 240 Hz
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 checkbox 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
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.

User Manual Page 2-15
Page 36
Note: When 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 one frame in length for these video formats.
Program Metadata 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 datastream 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
program 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:
Dialog Norm:
The normal audio level for dialog. 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 standard mode of operation and contains a complete audio program

When video and audio are in sync, the audio pulse will sound at the exact moment the white flash
appears. If video and audio are out of sync, there will be a differential delay between the timing of
these two events.
The LAWO V_line AV Sync test pattern provides a constantly moving progress bar. When the
progress bar reaches the center frame of the test pattern, first a vertical white bar then a white flash
appears in the center circle.
When video and audio are in sync, the audio pulse should sound at the exact moment the white flash
appears. When video and audio are out of sync, there will be a differential delay between the timing
of these two events.
To measure AV Delay in the Picture instrument, the Picture source should be set to the SDI input to
analyze the incoming video signal.
Note: The Picture source can also be set to view the generator output.

The A/V Delay selection menus and measurements display is located in the top right-hand corner of
the Picture instrument.
To measure the differential AV Delay, first ensure that a suitable test source is being used.
For the AV Delay measurement to be valid, the measuring Sx unit must be genlocked to a suitable
reference, defined as either of the following:
l
the SDI input being analyzed
l
the external reference to which the AV Delay test signal source device is locked.
If, however, the measuring Sx is also the source device generating the AV Delay test signal in a loop,
then a suitable reference is defined as either of the following:
l
External reference
l
Free run
Trying to lock the Sx unit to its own input signal is not valid.
The Sx unit reference input can be set in the Generator → GenLock page.
Switch on AV Delay measurement by selecting the appropriate test pattern type from the first A/V
Delay dropdown menu:
l
Select either:OFF, EBU, LAWO
In the next dropdown menu, select the required audio group and pair carrying the AV delay audio
pulse – the timing of which will be measured relative to the video test pattern.
The AV Delay pulse can be carried on an embedded SDI audio:
l
, G1-P1, G1-P2, G2-P1, G2-P2, G3-P1, G3-P2, G4-P1, G4-P2
The Left (L) and Right (R) channel fields will display any measured differential delay between the video
and that audio channel in milliseconds (ms).
The status of the AV delay measurement tool (when switched on) is shown by the color of the
measurement display fields:
Yellow
Sampling in preparation for A/V Delay measurement. Not accurate during this period.
White
Measured differential delay. No errors detected.
Red
The correct AV delay pattern has not been detected and/or no AV delay pulse has been
detected
Audio-to-Video Differential Delay Testing:
Objective: To measure the imposed differential delay of the audio and video paths in the system
under test.

Signal Data (Option:PHSXOSD)
The Signal Data menu shows the video signal as a data stream in several formats as described below.
In each 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.
To simplify scrolling around the SDI signal view, use the cursor keys to move the red focus rectangle
to the data display and press OK. The focus rectangle should change to a blue color and the cursor
keys allow the display to be scrolled in any direction. The menu keys at the bottom allow the Line /
Sample to be adjusted by 10 or 100 in any direction.
Note: Note that the line number of a line of video changes at the end of active video. This gives
the unusual 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.
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 three 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:
Comp:

The analyzer can view either the video SDI input one (In1), SDI input two (In2), the Generator output
one (Out 1) or output two (Out 2) so that comparisons can be made between input and output.
Note: Note that when in Color 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 checkbox is selected the values in the active picture are unpacked to
RGB or YCbCr values.

Waveform Monitor
The Waveform Monitor menu displays the selected input in the form of a waveform monitor.
The display may be restricted to a single line or all lines may be displayed at the same time. The
display can be formatted as all streams (Luma and Chroma) or just a single stream.
The streams may be in YCbCr or GBR formats. The line, sample and field controls all track the related
controls on other pages.
The All checkbox forces the waveform monitor to display all lines, overlaid on each other. Otherwise,
the specified line is displayed.
The waveform display format is set using the Setup button. The waveform monitor displays the
selected signal in one of five formats as set by the Mode control:
YCbCr
The Y, Cr and Cb waveforms are displayed as three separate waveforms in a Parade

The red, green and blue chroma channels are displayed as three separate waveforms in a
Parade format
XYZ, X, Y, Z
Settings in the Waveform monitor display the 2K-SDI XYZ color space in its native nonlinear form, so test patterns such as 2K. XYZ Legal Ramp will be displayed as curves
instead of straight lines.
X'Y'Z', X', Y, Z'
Settings in the waveform monitor display the 2K-SDI XYZ color space with a reverse transform to convert it to linear form, so test patterns such as 2K, XYZ Legal Ramp will be displayed as straight lines.
The next two controls show the vertical and horizontal magnifications. If either value is set to a value
other than x1, a vertical or horizontal offset is displayed at the bottom-right edge of the waveform
display. The offsets are set by moving the focus cursor to the waveform window and pressing OK.
The menu keys can then be used to scroll around the window. The offset is the same for all
magnification values so switching between x1 and x5 will not lose the offset used in x5 mode.
The vertical offset values are in signal level bits but displayed in the current scale units so switching
between scales will keep the same offsets.
Cursors
Cursors may be displayed over the waveform to allow measurement of time or amplitude values. The
cursor may be set to several modes:
Off:
Cursors are hidden
Pict.:
The cursor is displayed at the current pixel point. If in YCbCr or RGB mode, three cursors
are displayed. Otherwise a single cursor is displayed. The cursor position tracks across the
picture monitor and Signal Data tabs.
Ampl.:
Two cursors are displayed to allow measurement of signal amplitudes.
Time:
Two cursors are displayed to allow measurement of signal timing.
Both:
Amplitude and time cursors are displayed.
To use the cursors, use the navigation keys to move the focus to the waveform display and press OK.
You should then get a display similar to that below. Note that the menu keys shown depend on the
display mode and cursor mode.
The navigation keys now move the selected cursor around the waveform display which will scroll if
moved out of the visible area. The x10 and x100 buttons magnify the action of the navigation keys if
held down.
The Select Window button is only available in YCbCr or RGB modes and selects the window in which
the cursor is displayed.
PHABRIX SxD
User Manual Page 2-27

The Amplitude Cursor and/or the Timing Cursor buttons switch the currently active cursor. In each
direction two cursors are displayed. The currently active cursor is the one displayed as a full line
(rather than the dotted cursor). The bottom of the waveform screen shows the cursor measurements
in the current format which may be Decimal, Percentage or Hexadecimal for amplitude
measurements or Pixels/µs for timing measurements. The difference between the two cursors is also
displayed in absolute form.
The Cursor Mode button changes the current mode without having to leave the navigation window.

Signal Information Menu
Overview
The Sig Info pages give a detailed view of the status of the input (or generator output) signal. They
are sub-divided into Video, Misc, and Ancillary (ANC) Status.
Video Status
The Video Status menu shows the status of the selected video input and displays any errors found in
the datastream.
CRC/EDH Errors
The CRC/EDHErrors section displays the EDH or CRC status of the analyzer input as appropriate for
the video standard being monitored. The status of each CRC/EDH 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
intermittent. CRC errors are ignored on the switching line if the Ignore switch line checkbox is
checked.
ANC checksum errors are also detected and counted and may be logged.
When analyzing a 3G-Level B signal, the CRC status is displayed for each link or stream present
according to the input video format.
With the SxD dual-link instrument using two video inputs, only one 3G-Level B signal may be analyzed
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.
Page 2-30
PHABRIX SxD
User Manual
Page 51
The EDH flags for active picture, full-field and ancillary data are also displayed for diagnostic
purposes:
ues:
Unknown error status: Set to 1 if the previous device received an SDI signal from a device
not supporting EDH.
ida:
Internal Error Detected Already: Set to 1 if an idh flag was received by the previous device.
idh:
Internal Error Detected Here: Set to 1 if a hardware error was detected in the previous
device.
eda:
Error Detected Already - Set to 1 if an SDI error was detected in the signal received by the
previous device.
edh:
Error Detected Here - Set to 1 if an SDI error was detected. In the case of ancillary data, this
means that one or more ANC data packets had an incorrect checksum.
Note that there is only one EDH detector which is connected to the input currently being analyzed.
On an Sx instrument with multiple video inputs, only the current input being analyzed can check for
EDH errors.
Cable Length
The Sx 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:
l
Belden 8282, 1694A, 1505, 1855A.
l
Canare L-5CFB
l
Image 1000
l
Percon VK 5
l
Draka 0.6/2.8 AF
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.

Misc Status
The Misc Status menu displays the auto-detected and SMPTE ST352 (VPID) parameters of the
selected SDI source and highlights any detected errors or unsupported parameters.
When analyzing a 3G-Level B signal, the SMPTE 352 status is displayed for each link or stream
present according to the input video format.
With the SxD dual-link instrument using two video inputs, only one 3G-Level B may be analyzed for
SMPTE 352 status at a time.
Note: The Sx now supports the SMPTE 352 video payload identifier (VPID) on a single interface
of 4 x 3G and 4 x 1.5G links.
Payload ID – SMPTE 352
If the Sx instrument detects a SMPTE 352 ancillary packet, the detail of the packet content is

Video Format
This section displays the currently auto-detected pixel counts, active line count and the frequency of
the selected input source.
Note: The displayed video frequency is correct only if the Sx 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, for example, ifthe line count or pixel count is not recognized,
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-synchronized and can
help detect intermittent SDI signal problems. Press Clear to reset this counter.
Video Timing
The Video Timing menu displays the relationship between the selected video input with respect to
the locking reference input.
The timing of the 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 a black font, 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 microseconds.
The red arrow on the bar shows the SDI input timing and the blue arrow shows the current target
timing point. The brown vertical 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 two offset fields, press OK to edit them and then
press Default.

Note: 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 from other test and measurement instruments that
include an SD (PAL/NTSC) offset in their calculations. By comparing line 1 timings, the Sx
instrument can be used to measure time delays accurately through up / down / cross converters.

ANC Status
The Ancillary Packets Status tool provides broadcasters, studios, OB and broadcast manufacturers
with a detailed analysis of the ancillary data present in an SDI signal.
A simple grid layout provides a quick overview of the available VANC/ANC ancillary data for an
engineer. The packet type is then displayed as present, absent or red if in fault. Simple icons next to
the packet indicate the fault. Each ancillary packet available from the grid view can be set to enable
logging and then presented together with other information in the events window of the logging
menu.
This tool further allows additional user-defined selections with the appropriate DID or SDID code. Any
ancillary packet code can be saved down for future recall. Note that the Ancillary Packets Status tool
does not fully decode the ancillary data but is used to identify whether the packet is present in the
signal.
The ANC Status menu shows which ANC packets are present on the SDI input and whether they
have any errors. Each field is color-coded according to whether the ANC packet is present (White),
missing (Grey), has errors (Red), or has previously had errors (yellow).
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 state.
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 three 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 Data Option:PHSXOSD)
The SDI Data Option PHSXOSD allows Ancillary data packets to be detected and checked for errors.
The ANC Inspector menu displays details of the ANC packets.
The packet type can be selected using either the dropdown list of known packets or the DID/SDID
number fields. If the DID/SDID values match a known type, then that type will be selected in the
dropdown list. This may be further filtered using the checkboxes on the Setup dialog.
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 checkbox.
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 detected ANC packets may be filtered using the Setup dialog. This allows a great deal of
freedom in setting when the display will be triggered.
If the On Trigger checkbox is selected the data packet will cause the display to be frozen and the
Freeze checkbox will turn red when a trigger condition is met as described below. Uncheck Freeze
to 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.

ANC Inspector Setup
If the Setup button is pressed a dialog box allows the ANC packet trigger parameters to be set. The
trigger parameters allow only selected lines to be checked or excluded when checking for the
presence of packets.
Line Range Filter:
If either of the Line Range filter checkboxes are checked then the range of lines that the
ANC inspector will check is restricted to that range. If the dropdown below the range is set
to Inside then it will only check ANC packets within the range (including the start and end
lines). If set to Outside it will check only ANC packets outside the specified range.
HANC/VANC Filter:
Provides another filter for simpler selection of the area in which to search for packets. It
may be selected to search the HANC area, the VANC area, or both areas.
Error Triggers
If any of the Errors checkboxes are selected, then the ANC packet data will only be displayed if an
error occurs. The error states detected are:
Checksum:
DBN:
Parity:
A checksum error in a packet was detected. (Sum of data between DID and final UDW)
A Data Block number error was detected in an audio packet. The DBN field (in the same
place as the SDID) of an audio packet should either be 0 and never change, or increment
from 1 to 255 and then start at again at one.
PHABRIX SxD
User Manual Page 2-37
Page 58
A parity error was detected for the DID, SDID and DataCount words in a packet. (Even Parity used and bit 9 is the inverse of bit 8.)
ANC Gaps:
The ANC packets were separated by a gap containing video blanking data. EDH (DIDD=0xf4) packets are ignored. Note that if an EDH packet is marked for deletion, this will result in an ANC GAP error.
The Setup dialog 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 dialog.
This dialog also allows the user defined ANC packets to be configured.

Dolby (Dolby Analyzer Option: PHSXO-DAG)
The Dolby Analysis 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 Dolby E aspect of the signal to be timed correctly 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
There are a number of Dolby broadcast digital audio standards that transport audio data over an
SMPTE 337M AES carrier with a 48 kHz sample rate:
l
Dolby E
l
Dolby Digital
l
Dolby Digital Plus
These standards can be used to transport mono, stereo, 5.1 and 7.1 audio programs:
Dolby 5.1
Involves five channels for standard-range speakers (20 Hz to 20,000 Hz) (right front, center, left front, rear right, rear left) and one channel (20 Hz to 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 remaining two channels in an ancillary program (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 eight channels of audio (mono, stereo, 5.1 or 7.1) that for a primary program (Program 1) and
optional ancillary programs. These eight channels are compressed (lossless) into a digital stream that
can be transferred between compatible devices and stored on a standard stereo pair of audio tracks.
The most elaborate mode in common use is Dolby 7.1 which uses all eight channels to provide
surround sound.
PHABRIX SxD
User Manual Page 2-41
Page 62
Dolby Digital
Dolby Digital (AC-3) is a
needs to deliver high-quality sound. This system was developed primarily for DTV, DVD and HDTV.
This format allows 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 offering a primary program and optional ancillary programs. These can be
optionally delivered at lower bit rates than Dolby Digital.
perceptual audio
system for digital audio that allows the reduction of data
Analyzer Reference
For correct decoding of Dolby E data, the internal audio circuitry requires a reference that is
synchronized to the input signal. The Generator Reference must not be set to Free-Run or Dolby E
errors may be detected. 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 present on one or more audio
pairs. The Sx instrument needs to lock its internal audio clock to the SDI signal Generator → GenLock
→ GenLockSource → Input-1 and the Dolby Timing source should be set to SDI.
Source Selection
The Dolby E may be monitored from any of the SDI input embedded audio channel pairs.
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 chain where
audio can be delayed by a different value to the video, the Dolby E packet needs to be re-timed to
ensure that this timing specification is met. The position of the Dolby E packet in the video frame is
displayed in lines and microseconds (µs).
Dolby E Timing Source
Dolby E timing may be measured relative to the SDI input or the External reference. If the Ideal
checkbox is checked, the Dolby E Frame timing is relative to the normal position that it should be, i.e.,
it should be as close to 0 as possible. Each video standard has a specified
the Dolby E packet should start. If the Dolby E timing line is outside the valid range of lines it will be
Ideal
line number on which

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.
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.
Note: If Dolby E is present on a fast frame rate signal (50p, 59p or 60p) then it should always be
referenced to an 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.

Network
PHABRIX Sx is fully network compatible and has a complete network interface to allow control of any
Sx instrument from any other unit.
The Network menu allows the Sx instrument to be configured as part of a network.
PHABRIX SxD
User Manual Page 2-51
Page 72
Note: If the Sx instrument is switched on without the network connected, you will have to select
Re-connect button to set networking up correctly. This is because the Ethernet connection auto-
senses whether it has to swap the cable over, which means that you can use any Ethernet cable
with the Sx instrument, but it also requires the Ethernet connection to be present when starting
up.
If the DHCP checkbox is enabled, then the Sx instrument will automatically attempt to request an IP
Address from any network to which it is connected, as long as a DHCP server is available on the
network.
If your network uses static (nonchanging) addresses, you will need to contact your network
administrator to get an address assigned to your instrument, and to get the Subnet mask and default
gateway address. To edit the settings, select Setup. These details can then be entered in the
corresponding boxes in the menu. If the DHCP checkbox is enabled, these values will not be
editable. 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
Re-connect to attach the Sx instrument to the network.
Remote Control of Sx Instrument (Option: PHSXOR)
To allow remote control of an Sx instrument, you must have the TCP/IP address of the instrument set
and the Remote Ctrl On checkbox selected.
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 Sx instrument uses a default Port Number of 2100 for remote control access (See Remote Control
SDK documentation on Download section of Web Site) This port number may now be changed if it
conflicts with other applications in your system.

Logging Menu
Overview
Logging allows events to be detected and recorded for future examination. The events to be logged
can be specified so that unwanted events do not appear in the event log. If a system has a problem
with intermittent signals, the Sx instrument can be connected to that source and can be left for several
days to log any errors. At the end of that period the log can be examined and the time and date of
each error noted.
Events Log
The Events menu displays a list of events with a time stamp showing when they occurred.
Entries in the Event Log are classified according to their severity with an initial letter as follows:
l
C: Control (change of state)
l
E: Event
l
I: Information
l
W: Warning
Pressing the OK button on the front panel when the highlight is on the event log page allows the
event log to be scrolled to view all events in the list. The currently selected event is shown on the
event log header. The date format may be changed using the date Format dropdown on the System
→ Misc page. The event log may be cleared by pressing Clear Log; a confirmation dialog will be
displayed . A date-stamped
mark
may be inserted into the event log to allow users to see when a test
started or when a significant event occurred using the Add Mark in log button.
Note: The event log displays only changes in status, so if the input is always in error and never
good, an event will not be recorded. To obtain a view of the complete state of the instrument
requires reviewing the current status in addition to the event log.

Log Setup
The Log Setup menu allows specific events to be tracked by the Sx instrument.
Note: The events to be logged are set-up on this page by checking the appropriate Log
checkboxes.
Audio Thresholds
This section allows the thresholds for audio events to be set. If the audio level for a channel is higher
than that specified in the Clip or High fields for the number of seconds specified, then an event will be
added to the event log. If the audio level for a channel is lower than that specified for the Quiet or
Muted fields, then an event will be added to the event log. Logging may be limited to specified audio
pairs.
Video Status
This section allows specific video status events to be logged:
Output Standard:
A log event will be added whenever the generator video standard changes.
Reference Status:
A log event will be added whenever the external reference standard changes or the
external reference input is lost or re-appears.
Input Status:
A log event will be added whenever the input video standard changes or if the input is lost
or re-appears.
EDH/CRC:
A log event will be added whenever an EDH/CRC error state changes. If the EDH/CRC
state is correct, the event will show OK, else it will show FAIL. Separate Luma and Chroma
CRC events may be shown. Note that EDH/CRC events may occur when an SDI signal is
connected or removed.
TRS Errors:
PHABRIX SxD
User Manual Page 2-61
Page 82
If the number of lines changes or line length changes during a frame, the input video will
be detected as the TRS changing and an event logged. If the signal continues changing
only a single event will be logged. If the SDI signal has a static line count and line length for
five seconds, a TRS OK event will be added to the log. This reduces the number of log
events for a bad SDI signal.
Picture CRC:
This should only be used for static single-frame test patterns (do not use for Zone Plate,
dynamic broadcast signals or Checkfield/Pathological test patterns which are two frames
long at HD). This can be used to log changes in the CRC for the active picture (a unique
value for each test pattern). If the CRC changes and was previously OK an error is added to
the event log. If the CRC is the same as the last frame for five seconds an OK event will be
added to the event log. If the active picture CRC is continuously changing, therefore, only
one event will be entered in the log until the picture remains static, at which point an OK
event will be added.
Dolby Status (Requires Dolby Analysis Option)
This section allows Dolby errors to be logged.
Errors:
Will add an event to the event log when a Dolby input stream is detected or lost. An event
will also be added if a CRC error is detected in the Dolby metadata stream. If an error is
detected in the Dolby E stream, it may mean that the Dolby E stream has not been synchronized with the embedded audio clocks.
Timing:
Will log if the Dolby E frame timing is outside the Dolby-specified Ideal range. A Warning
event will be given if the signal is OK but slightly outside the range and an Error event if it is
on an invalid line.
Common Metadata:
Will log any changes of the common metadata (Program Configuration, Bit Depth, Frame
Rates.)
Program Metadata:
Will log any changed program metadata. This can be useful for following changes to a program stream over a long period of transmission.
Logging
This section controls all logging events:

Speaker Menu
Overview
The Speaker menu controls which audio pair can be heard on the loudspeakers and headphone
output of the Sx instrument. The Sx instrument contains a stereo loudspeaker and associated stereo
headphone socket which can be connected to any of the audio input or output channels or pairs.
The Mute checkbox allows both signals to be muted.
A volume control is available to adjust the level to headphones and speaker together. The balance
control can be used to adjust the Left-Right balance for the source being monitored.
The monitored source can be set to the input or output of the Sx instrument, and the input and output
sources can be set independently to either a stereo pair or single audio channel.
The Source is used to select the specific input that is to be heard.
The speaker can be muted when headphones are plugged in by selecting the checkbox Mute Spkr
if Headphones.
Note: When listening to an audio source, the Sx instrument needs the audio to be synchronous
with that of the Sx Generator. If this is not the case, clicks will be heard on the speaker. Either
connect the Sx instrument reference to the same reference as the SDI input source and set the
Generator → GenLock → GenLock Source to External or Input-1.

HD-SDI (is standardized in SMPTE 372M).
AES
Audio Engineering Society
AES3-2003
Standard for digital audio — Digital input-output interfacing —Serial transmission format for
two channel, linearly represented digital audio data.
Alignment Jitter
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 center of the data
sample.
CPU
Central Processor Unit
CRC
Cyclic redundancy check is an error-detecting code commonly used in digital networks
and storage devices to detect accidental changes to raw data. Blocks of data entering
these systems get a short check value attached, based on the remainder of a polynomial
division of their contents; on retrieval the calculation is repeated, and corrective action can
be taken against presumed data corruption if the check values do not match.
DID
Data ID is part of the Ancillary Data that is transmitted with the SDI data.
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.
Dolby Digital Plus
(E-AC-3) is a more advanced version of Dolby Digital that provides a more efficient encoding algorithm that provides enough bandwidth that allows up to 20 channels of audio (for a
primary program (Program 1) and optional ancillary programs that can be delivered at much
lower bit rates than Dolby Digital.
Dolby E

UI
Wander
A short-term time interval error above a low frequency threshold of 10 Hz (as defined in the
SMPTE standards for SDI signals).
(Unit Interval) is time between consecutive clock cycles used to sample the SDI data
stream. The UI measurement is used for Eye Pattern measurement.
A long-term time interval error, i.e., artifact below 10 Hz. Typically, all video equipment has
the tendency to cause wander over a long period; these artifacts are not easily displayed
in a meaningful way but are better logged as errors that exceed tolerances over a long
period.

Operating Environment
Operating Temperature:
0° to 40°C
Operating Humidity:
< 85% RH (non-condensing)
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°Celsius a warning dialog will be given. If the temperature rises
above 65°Celsius the unit will be switched OFF.
Under both conditions, an event will be added to the event log to show what happened.
Expected Behavior
LCD Monitor
The LCD may have some pixels that are always turned ON or always turned OFF. This is normal and
should not affect normal operation.
LCD Flicker
The unit supports many video standards. The input SDI signal is displayed asynchronously and may
flicker on the waveform display or picture display. The unit stores the input SDI signal internally, and
then reads the internal frame using the LCD sync signal, which is asynchronous to the input SDI
signal. LCD flickering may occur if a frame is skipped or repeated.
Remote Network Operation
Remote network operation is only guaranteed when connected to a local machine.

Maintenance
Warranty
Overview
The Sx range benefits from a standard one year warranty including telephone and email support. You
can choose to extend the warranty period for your device to either three or five years.
Each Sx leaves our UK factory with its own unique list of quality-controlled settings which are
recorded by our manufacturing department. Should the Sx require calibration, these settings are
compared with its pre- calibration state to ensure consistency and traceability.
The product has been designed and manufactured to be of the highest quality. However, should the
instrument develop a fault during the warranty period, please return to your local PHABRIX agent for
repair.
Calibration services are available throughout the PHABRIX network of distributors, see:
https://www.phabrix.com
Warranty Exceptions
PHABRIX are not responsible for free service during the warranty period under the following
conditions:
l
Incorrect voltage applied to instrument.
l
Incorrect power adaptor used.
l
Fire, natural disaster.
l
Repair of instrument by non-PHABRIX approved agent.
l
Repair of damage caused by third party products.
l
Repair of damage caused by improper use.
l
Repair without proof of purchase.
Product Registration
Please register your product on-line at: https://www.phabrix.com
Registering your product with PHABRIX ensures that you receive free email and telephone technical
support, plus free software updates during your product’s warranty lifetime.
Maintenance
General Maintenance
The Sx instruments have been designed to need minimum maintenance. The use of low power
components means that there is no need for large amounts of cooling and therefore there is no need
to clean fan filters.
