MODULE OVERVIEW
The 5400 module is a stable timing source suitable for local reference generation for use
in broadcast, remote trucks and post-production. Dual outputs, available simultaneously
in analog composite and serial digital and an HD tri-level sync reference output are
provided. In addition, more than twenty internally-generated test signals, including black
and color bars, and EDH Error generation are available.
The 5400 can operate from an internal precision frequency reference as a stand alone
master sync generator or lock to a video reference from an external source. The module
can also lock to an external 10 MHz source such as an atomic standard or GPS receiver
for more precision.
Two sets of composite outputs and serial outputs are provided. One serial output together
with a pair of composite outputs form the primary sync generator. A second serial output
together with an associated pair of composite outputs form a separate secondary sync
generator.
The test signal generator is always output to the primary outputs. An ID slate with user
programmable text can be overlayed on the test pattern. The secondary sync generator
always outputs color black.
The Primary and Secondary outputs can be timed with respect to the reference to any
point in the television frame. Color framing tracks the reference signal. Timing adjustments for primary and secondary outputs are configured independently and the 5400 can
be configured to output 525 and 625 standards simultaneously.
An optional submodule, the 5410, can be installed to provide audio test signals, AES3id,
word clock or 6 Hz output, analog tone and embedded audio reference outputs. The AES
outputs are synchronous to the 525 and 625 outputs as they share the same time base.
The Primary 601 output will have EDH checksums inserted.
Another feature available when the 5410 submodule is installed is the Make EDH Error
function which deliberately introduce different types of errors in the Primary SDI output.
EDH (Error Detecting and Handling) is a method to detect and indicate loss of data path
integrity and corruption. A CRC (Cyclic Redundancy Character) checksum is computed at
the point of transmission and inserted in a special data packet in the vertical interval of
the signal. At downstream locations, this CRC can be recovered and checked against a
value which has been locally re-computed from the same video data stream. If the transmitted CRC and the re-computed CRC values match, there have been no errors in transmission.
As shown in the block diagram on the following page, the time base reference is selected
from either the Master or Genlock (external) reference. The selected reference passes
through a precision sync separator to derive the required sync components. The separated
sync signal provides the timing reference for the PLLs.
These primary timing signals then pass through timing adjustment and burst detection
circuitry to determine color field sequence. They are then used to generate the test signal
pattern and black test signals in their respective generators. The test signals pass to the
Primary and Secondary serial outputs and also enter composite encoders to provide the
Primary and Secondary composite analog outputs.

Model 5400 Dual Sync Gen/Test Signal Generator
The Tri-Level Sync output is analog timing reference intended for use with high definition
equipment. It uses the same time base as the Primary sync generator and can be framesynchronized when their output standard match.
If the optional 5410 submodule is installed, the reference signal passes to the submodule
where an AES tone and word clock are derived. This audio information can be embedded
into Group 1 of the Primary serial output and also passes to the output BNCs as the
audio references. It is also sent to a D-to-A converter where it is converted to analog
composite audio and feeds the rear Audio Out 15-pin connector.
Test patterns can be overlayed with an ID slate configurable in the remote Avenue PC or
Touch screen option interfaces. The slates can also be enabled by remote control with GPI
closures accessible from the 15-pin Audio Out connector.
A special feature that adds motion to the test signal can also be inserted along with the
Slate ID or, independently of it. This feature, called Cyclops, indicates true frame motion
from the test signal with an on-screen indicator that moves from side to side. It can
indicate whether the signal is live or has frozen, such as when a frame synchronizer loses
it input and freezes. Additionally, audio left and right channel indicators can be enabled to
synchronize with the Cyclops to verify audio connectivity and timing.
Power is derived from the ± 12 volt frame power. It is regulated to the required +5 volts
for the module by on-board regulator. The module is fused with a resettable fuse device. If
the fuse opens due to an overcurrent condition, the module will lose power. After pulling
the module, the fuse will reset automatically requiring no replacement fuse.

The on-board CPU can monitor and report module ID information (slot location, software
version and board revision), and power status to the optional frame System Control
module. This information can be accessed by the user or set to register an alarm if desired
using the remote control options available.
APPLICATIONS
Simultaneous References
As shown in the application below, the 5400 module can provide simultaneous 525, 625
and AES reference outputs, all derived from the same time base, all from the same
module.
Digital, Analog and Audio Reference Generation and Distribution
Another application shown below, illustrates how the 5400 module can provide digital,
analog and audio reference outputs which can then be distributed throughout a facility
when combined with the 5125 Dual DA and the 5150 DA. Audio reference signals are
available when the 5410 submodule is installed.

5410 Submodule
Install the 5410 submodule by lining up the connectors on the submodule with the connectors on the 5400 module. The connector is keyed to prevent installing it incorrectly.
AES B Out Jumper
A jumper, AES B OUT, J3, on the 5410 submodule (shown below) allows the user to select
the type of audio output on the AES Out 2/Wordclock BNC on the rear of the module.
When AES is selected, the output will be an AES3id signal from the BNC. Setting J3 to
WD_CLK, allows either a Wordclock output or a 6 Hz 4.5 align pulse, used in telecine
applications. When set to WD-CLK, the pulse type must be selected in the Pulse Select
pulldown in the Avenue PC or Touch Screen Config menu.
5400 Module
Plug the 5400 module into any one of the slots in the 3 RU frame and any slot except Slot
3 in the 1 RU frame. Install the plastic overlay provided onto the corresponding group of
rear BNC connectors associated with the module location. Note that the plastic overlay
has an optional adhesive backing for securing it to the frame. Use of the adhesive backing
is only necessary if you would like the location to be permanent and is not recommended if
you need to change module locations. This module may be hot-swapped (inserted or
removed) without powering down or disturbing performance of the other modules in the
system.
CABLING
Refer to the 3 RU and 1 RU backplane diagrams of the module on the next page for

MODULE CONFIGURATION AND CONTROL
The configuration parameters for each Avenue module must be selected after installation.
This can be done remotely using one of the Avenue remote control options or locally using
the module front panel controls. Each module has a REMOTE/LOCAL switch on the
front edge of the circuit board which must first be set to the desired control mode.
The configuration parameter choices for the module will differ between Remote and
Local modes. In Remote mode, the choices are made through software and allow more
selections. The 5400 Parameter Table on the following page summarizes and compares
the various configuration parameters that can be set remotely or locally and the
default/factory settings. It also provides the default User Levels for each control. These
levels can be changed using the Avenue PC application.
If you are not using a remote control option, the module parameters must be configured
from the front panel switches. Parameters that have no front panel control will be set to a
default value. The Local switches are illustrated in the Front Panel Controls and
Indicators section following the 5400 Parameter Table.
Avenue module parameters can be configured and controlled remotely from one or both of
the remote control options, the Avenue Touch Screen or the Avenue PC Application. Once
the module parameters have been set remotely, the information is stored on the module
CPU. This allows the module be moved to a different cell in the frame at your discretion
without losing the stored information. Remote configuration will override whatever the
switch settings are on the front edge of the module.
For setting the parameters remotely using the Avenue PC option, refer to the Avenue PC
Remote Configuration section of this document.
For setting the parameters remotely using the Avenue Touch Screen option, refer to the
Avenue Touch Screen Remote Configuration section of this data pack following
Avenue PC.
Model 5400 Dual Sync Gen/Test Signal Generator
5400-9
Making Reference Choices
Each generator can be independently set to operate either as a Master Sync Generator
(using an internal precision frequency reference), or genlocked to an external reference
source of either composite video or a 10 MHz sine or square wave. In addition, the
secondary generator can be set to lock to the primary generator in tracking mode. These
choices are made using the Pri and Sec Source controls in the Primary and Secondary
menus. Refer to the block diagram below.
When a generator is set to be genlocked (by selecting Config Ref in the Pri or Sec
Source menu), a further selection must be made to configure the module to use either its
external genlock BNC (labeled Genlock/10 Mhz In on the module backplane) or the
Master Frame Reference which is distributed through the Avenue frame backplane. This
choice is made in the Config menu and provides the configured reference for both generators. The module will accept analog composite NTSC (525) or PAL (625), or a 10 MHz sine
or square wave as an external genlock signal.
In order to provide the ultimate in flexibility, the television line standard output for each
generator can then be set to either 525/60 Hz or 625/50 Hz. These output choices are
possible even when the generators are locked to a genlock input in a different standard.

625 or 10 MHz sine wave) or Master Ref (Frame Reference).
The presence of the reference will be reported in the adjacent window.
• Pulse Select – set the type of pulse output desired for the AES Out 2/Wordclock
BNC on the rear of the frame. (Note that to enable a Wordclock or 6 Hz Pulse
output, jumper J3 must be set to WDCLK on the 5410 submodule. Refer to the
Installation section of this data pack for an illustration of this jumper.)
• Make EDH Error – this function allows introduction of specific EDH errors into
the SDI output stream for.testing downstream equipment. when the 5410 option is
present It can also be used to verify that corrective action or alarms are generated
at those downstream points as needed or expected. This mode resets to No Errors
upon reset or power is cycled (setting is not stored in non-volatile memory.) Error
types are summarized as follows:
• AP CRC Error – causes incorrect CRC for active picture to be transmitted
in EDH packet. Simulating a bit error, this should be detected as an EDH
error by downstream equipment.
• FF CRC Error – same as AP CRC Error above except it is the Full Frame
which is transmitted incorrectly.
• AP EDH Error – causes the AP EDH flag in the EDH packet to be set.
This simulates an error which was previously detected by upstream
equipment. The actual CRC will be correctly computed. This should be
detected downstream as an EDA error (Error Detected Already).
• FF EDH Error – same as AP EDH Error above except the Full Frame flag
is also set.
• AP EDA Error – causes the AP EDH flag to be set. This simulates a
stream where an error was detected by previous equipment. This error
should continue to be reported as EDA at every subsequent downstream
location.
• FF EDA Error – same as AP EDA Error above except also sets the Full
Frame flag.
• AES RefLvl – set the AES reference level to either -20 dB or -18 dB depending on
the audio requirement.
• Anlg RefLvl – set the analog reference level from –10 dBu to +8 dBu for the
Analog Tone Output.

can be easily monitored from the front panel of this module using the front panel indicators.
Refer to the overall troubleshooting tips given below for the 5400 module:
Error light is lit on front panel:
• Module is not locking to a selected reference. At least one of the Ref LEDs
should be lit to indicate presence and status of reference input
No Pri or Sec LED indication:
• Module is not locking to 525 or 625. At least one of the Pri or Sec LEDs
LEDs should be lit to indicate locking status.
Can’t control module:
• Check status of CPU Run green LED. Should be blinking slowly and in
unison with other modules if System module is present. If not, try removing
it and plugging it in again to be sure it is seated properly.
• System module may not be working properly if installed.
Module controls are grayed out:
• Module is locked or access to module controls is restricted by User Level.
• Local/Remote switch on module is in the Local position.

A.2 TEST PATTERN DESCRIPTIONS
Color Bars
All of the color bar patterns include peak white, black, and the six vector colors (yellow,
cyan, green, magenta, red, and blue), either at 75% or 100%.
Full Field Bars
Full field bars is sometimes called simple bars as it does not include anything else.
It is color bars from the top of the field to the bottom.
100% is usually used for component signals as the amplitude of the Cb and Cr
signals is the same as the Y signal. A waveform monitor can be used to align Y, Cb,
and Cr gain.
75% is more commonly used with composite--when viewed on a waveform monitor,
the chroma yellow and cyan envelope is lined up with the peak white level. As
such, a waveform monitor can be used to align luminance and chrominance gain,
and a vector display can be used to align chroma phase.
Split Field w/Pluge
Pluge, or level reference is added to the color bars to make a split field. The pluge
is used to adjust monitor brightness and to check for clipping in digital systems.
The pluge includes +/- 2 IRE levels around black, four luminance steps, and a 5
IRE "top hat" above peak white.
In composite systems, monitor brightness can be adjusted using the +/- 2 IRE
levels around black by making the right-most level disappear in the adjacent black
while making the left-most level just visible.
In digital systems, the number of steps of dynamic range is limited by the number
of bits used to represent them. Black is represented by 040h and white is represented by 3ACh. If clipping occurs in the digital processing of a signal, the "top
hat" and/or the 2 IRE superblack level can be clip off.
5400-A2
Model 5400 Dual Sync Gen/Test Signal Generator
SMPTE Color Bars
In addition to pluge, SMPTE Color Bars includes a reverse sequence of bars.
The reverse sequence helps adjust monitor levels on monitors that provide blue
only displays. Hue can be aligned by balancing the chroma bars, and chroma can
be set by matching the chroma bars to the white bars.
Black Test Patterns
These test patterns are field field luminance reference levels. Black can be used as a color
black reference signal and the others can be used as flat luminance mattes.
Black
The composite black test pattern has characteristics that are described in the
following table:
Characteristic Requirement
Black Level 7.5 +/- 1 IRE (NTSC)
0 +/- 1 IRE (PAL and Japan*)
Blanking Width 10.9 +/- 0.2 uSec
Sync Level -40 +/- 2 IRE (NTSC)
-300 +/- 15 mV (PAL)
Sync Width 4.7 +/- 0.1 uSec
Burst Level 40 +/- 1 IRE (NTSC)
300 +/- 15 mV (PAL)
Burst Frequency 3.579545 MHz (NTSC)
4.43361875 MHz (PAL)
SCH Phase 0 +/- 3 degrees
Color Field Sequence 4 Fields (NTSC)
8 Fields (PAL)
* Setup is removed with an on board jumper
The serial black pattern has a narrower blanking width of 10.2 uSec.
50%, 80%, and Peak White
These full field luminance mattes have 10 bit luminance levels of 1F6h, 2FDh, and
3ACh.
5400-A3
Model 5400 Dual Sync Gen/Test Signal Generator
Ramp Test Patterns
Ramp test patterns are very useful for evaluating linearity, missing bits, timing errors,
and dynamic range.
If there is a problem with linearity, the ramp will not be a straight line. If there is a
missing bit, the ramp will be broken up into smaller ramps. If there is a timing error,
vertical lines which are often noisy can appear. If there is a dynamic range problem,
clipping will occur at the top or the bottom of the ramp.
Video Ramp
The video ramp test pattern goes from black to peak white across the line (040h to
3ACh for luminance and 040h to 3C0h for chrominance). Because there are more
samples in an active digital line than levels of gray and chroma, there are some
repeated steps across the line. This pattern is used especially for linearity, missing
bit levels, and timing errors.
Data Ramp
The data ramp test pattern goes from minimum to maximum legal digital values
(004h to 3FBh) in one step per sample increments. The ramp therefore restarts
part of the way across the line. Because it uses the entire dynamic range, it is
especially useful to check for clipping in each of the component channels, Y, Cb,
and Cr.
Shallow Ramp
The shallow ramp test pattern goes from 1E2h to 21Dh passing through the
critical 1FFh/200h point where all 10 bits change state. This pattern can be
examined closely using a waveform monitor to evaluate DAC/ADC step size uniformity and can be used to detect timing errors.
5 Step Ramp
The five step ramp test pattern has five steps:
Step 0: 040h and 040
Step 1: 0F0h and 0F4h
Step 2: 1A0h and 1A8h
Step 3: 252h and 25Ch
Step 4: 300h and 310h
Step 5: 3B0h and 3C4h
This pattern is used for aligning display systems such as a projector.
DAC Test
The DAC Test Pattern is alternating vertical bands of 1FFh and 200h across the
line.
At the transitions between 1FFh and 200h, all 10 bits of a digital signal change,
which can be problematic in DACs. Normally this step should not be visible on a
monitor, but if there is a problem, then vertical stripes will appear.
5400-A4
Model 5400 Dual Sync Gen/Test Signal Generator
Sweep Test Patterns
Sweep test patterns are used to evaluate frequency response by examining the envelope of
the waveform on a waveform monitor.
Full Field Sweep
Luminance sweeps to 5.75 MHz and chrominance sweeps to 2.75 MHz.
Sweep with Markers
The addition of markers at 0.5, 1, 2, 3, 4, and 5 MHz in the luminance channel and
0.25, 0.5, 1, 1.5, 2, and 2.5 MHz in the chrominance channel assist in evaluating
response.
Multiburst
Instead of continuous sweep, discrete frequencies are positioned across the line.
Luminance frequencies are 0.5, 1, 2, 3, 4, and 5.75 MHz, and chrominance frequencies are 0.5, 1, 1.5, 2, 2.5, and 2.75.
Pulse and Bar Test Patterns
These test patterns are used to evaluate transient response and clamp performance.
Chroma-to-luminance delay, short-term distortion, gain, response, and tilt can be
measured.
Window
The window test pattern is comprised of a 2T pulse, a modulated 12.5T pulse and a
window bar.
The 2T pulse is used to measure short term distortion such as K2T, and transient
response such as KPB.
The modulated 12.5T pulse is used to evaluate chroma-to-luminance delay. When
viewed on a monitor, the bottom of the chroma envelope ideally appears as a flat
line. Group delay can distort the bottom of the envelope and, with the appropriate
waveform monitor graticule, can be measured.
The bar can be used to measure gain, and is also used to measure short-term distortion such as K
SD
and tilt such as K
BAR
.
Full Field Window
The window bar in this test pattern extends vertically for the full field.
Component Window
The component window test pattern has window bars added to the pattern. The
leading and trailing edges of the bars use T steps for both luminance and chrominance edges. Since the sampling frequency for chrominance is half that of
luminance however, the chrominance rise time is half that of the luminance. The
window bar also has an inverted 2T pulse in its midpoint.
The amplitudes of the three components are: Y-3ACh, Cb-3C0h, and Cr-040h.
Window 100/20
These window test patterns can be used for color balancing video monitors.
Window 20 provides a centered window with a luminance level of exactly 20% of
full white. Your monitor manufacturer will have provided instructions on the use of
test patterns such as these.
5400-A5
Model 5400 Dual Sync Gen/Test Signal Generator
Timing Test Patterns
Timing test patterns are used to evaluate blanking area, field location, relative luma and
chroma timing, and cositing.
Analog Blanking Markers
The analog blanking markers test pattern draws a box around each field to show
the limits of blanking in composite systems. The size of the box is different for
NTSC than for PAL. In NTSC, the top of the field is at 21/284 and the bottom is at
262/525. In PAL, the top of the field is at 24/337 and the bottom is at 310/622.
The left and right markers are separated from digital blanking, which is narrower,
by a step so that actually blanking edges can be observed after passing through a
process that imposes blanking.
Digital Blanking Markers
The digital blanking markers test pattern draws a box around each field to show
the limits of blanking in digital systems. The size of the box is different for NTSC
than for PAL. In NTSC, the top of the field is at 20/283 and the bottom is at
262/525. In PAL, the top of the field is at 23/336 and the bottom is at 310/623.
The left and right markers are immediately inside EAV and SAV.
Cosite
The cosite test pattern assists in determining that the luminance and chrominance
parts of a digital signal are occurring in the appropriate relative time.
The vertical magenta pinstripe consists of a single cosite pulse in Y, Cb and Cr.
Because they are cosited and are only one sample wide, a mistiming of these components will not appear magenta on a monitor. Cb and Cr can be determined easily
on a waveform monitor because Cb is smaller than Cr. The levels are as follows:
Y-1B7h, Cb-3C0h, Cr-340h. The pinstripe is also useful because it is in the middle
of the line.
Interlace
The interlace test pattern is helpful to show that field 1 and field 2 are occurring in
the correct relationship to each other. A horizontal field timing strip and field 1/2
markers are included.
The horizontal field timing strip can be used to show that field 1 and field 2 are
cosited in time. The middle segment of the strip, which happens during field 1,
should occur between the outer segments, which happen during field 2. If it does
not, then the relative timing is shifted or the fields are swapped or missing.
The field markers help to identify which field is which. Field 1 has a roman
numeral "I" in it, and field two a roman numeral "II". If a field is missing, as in a
frame store in field mode, one of these markers will be missing. When viewed on a
waveform monitor or oscilloscope, the fields can also be identified. The field 1
marker has chroma content while the field 2 marker does not.
Bowtie
The bowtie test pattern is used to accurately measure the chroma to luma delay in
component systems in conjunction with a waveform monitor that is designed to use
it.

5400-A6
Miscellaneous Test Patterns
The following test patterns have special purposes.
Crosshatch
The crosshatch test pattern consists of horizontal and vertical lines organized in a
grid. This test pattern is used to evaluate monitor linearity and distortion.
SafeTitle
The safetitle test pattern identifies safe area in a video monitor for titles. If the
title stays inside the safe area, then monitors will always show the complete title
uncropped. The safe title pattern also shows the center of the visible area.
Unit Circle
When viewed on a component vectorscope, the unit circle test pattern displays a
circle of constant radius. This test pattern is useful for evaluating systems that
manipulate chroma such as chroma keyers.
Multi pattern
The multi pattern test pattern contains horizontal strips of other test signals,
including bars, reverse bars, pluge, video ramp, shallow ramp, sweep, markers for
sweep, multiburst, window, interlace, unit circle, and pathological patterns.
Viewed on a monitor, problems in a video system can often be discovered because
of the wide variety of signals present.
This single pattern can be used in conjunction with a waveform monitor that is
equipped with a line selector to display each of these patterns by selecting the line
to be viewed.
Multi composite
This test pattern is the same as the multi pattern above except the composite
version has the chroma channels of the ramp at reduced amplitude so that they do
not create illegal waveforms in composite.
Pathological
The pathological test pattern consists of a flat field of magenta color that is
precisely chosen because it produces long sequences of ones and zeroes in serial
digital systems. Because some systems are not tolerant of long sequences, this
pattern can help to identify those systems.
When a pathological error occurs, this test pattern shows horizontal, intermittent
black lines.
16 by 9
This pattern is intended for use in standard definition systems that are producing
anamorphic material for 16:9 HD viewing. This pattern provides safetitle marking
for both SD and HD aspect ratios. It also includes a color bar pattern which is horizontally compressed such that when displayed on a 16:9 monitor, the color bar
portion will have a 4:3 aspect ratio.
