Proper Video Termination

Improper termination of the video outputs will result in degradation (ringing, undershoot and/or
overshoot) of the test signals. The following figures show suggested methods for connecting
the video generator to displays having 50 and 75 Ohm input impedances in both differential and
single ended modes of operation.

1) The firmware includes a library of over 100 standard video formats. This is a common library
shared by all our Model 801, 802 and 822 series video generators. As part of the factory
initialization of each unit, the firmware scans all of the library formats for compatibility with a
given model and hardware configuration. All compatible formats are added to the knob list.

2) The firmware includes a library of over 100 built-in test images (patterns). This is a common
library shared by all our Model 801, 802 and 822 series video generators. Some test images
may not be compatible with some video formats and hardware configurations. An on-screen
message indicates these patterns are not supported when they are selected.

3) User defined video formats and custom test images can be stored in the generator using
Quantum Data’s MS-Windows

® based VGM software.

Special Operating Modes

Probe Sync Pulse Output

The FS connector on the sync module can output a TTL Level probe
pulse that can be used to trigger an oscilloscope or to synchronize a
camera used in automated vision systems. The pulse can be
positioned manually by the operator or by commands sent by a test
system. The horizontal timing can be set to a given pixel clock cycle relative to either the horizontal
sync pulse or the start of active video for a given line. The vertical timing is set to a given scan line
relative to either the vertical sync pulse or the start of active video in the frame. A marker can be added
to the video outputs when the pulse occurs during the active portion of the video test signal.

Example of Using the Probe Pulse Feature

Let’s say the image displayed on the monitor looks bad at (900; 200); i.e. it is bad on active line # 200 at
active pixel # 900 on that line. You can set the probe pulse to trigger an oscilloscope to look at the video
signal for that position as it passes through the monitor’s circuits.

Manually Operation of Probe Pulse Feature

1 ) Turn the test signal outputs off using the “Outputs” button (if not already off).
2 ) While holding down the “Image/Step” Button, press the “Outputs” button to turn the outputs on.

3) The generator will output the same video format and test image that
were last selected. The LCD window will change to the Probe Pulse
User Interface shown here. The video and sync gating buttons get new
functions in this operating mode. You can not use the buttons to gate
colors or change sync gating when the probe pulse feature is active.

P:nnnn X:nnnn
L:nnnn Y:nnnn

The number after “P:” is the position of the probe on a given scan line relative to the leading edge of
horizontal sync measured in pixel clock cycles. The number after “L:” is the number of the scan line
relative to the leading edge of vertical blanking. For interlaced formats the line number is relative to the
start of blanking for the first field. If the horizontal probe position is within the active area of the screen,
then the X coordinate of the pixel (X:nnnn) is also displayed. Likewise, if the vertical position of the
probe is in the active area, then the Y coordinate of the line (Y:nnnn) is also displayed. For interlaced
formats, the L count will move the probe in consecutive lines in one field of video and then move on
through blanking and the next field of video. This will cause the Y count to increment in steps of two.

The Format knob adjusts the “P:nnnn” horizontal timing probe position, while the Image knob adjusts
the “L:nnnn” vertical timing probe position. The knobs have an exponential taper which is reset
whenever the knob reverses direction. This feature provides boath coarse and fine adjustments (i.e. you
do not have to rotate the knob a thousand times to get to where you are going.). You can also use the
sync gating buttons lock which digits are changed by the knobs. Pressing the “ACS” button will cause
the knobs to step the counts in 100 unit increments. Pressing the “DCS” button will cause the knobs to
step the counts in 10 unit increments. Pressing the “DSS” button will cause the knobs to step the
counts in 1 unit increments. Pressing the same button a second time will revert the knobs to exponential
operation.

Special Operating Modes

Probe Sync Pulse Output (Continued)

There are two additional Probe Pulse operating modes available when outputting a progressive (non­interlaced) video format. Pressing the “R” video gating button will produce a probe pulse for each scan
line that contains active video. The bottom row of the LCD will show "Probe all active" in this mode.
Pressing the “G” video gating button will produce a probe pulse for each scan line (both active and
blanked). The bottom row of the LCD will show "Probe all lines" in this mode. Pressing a button a
second time will switch back to a single pulse per frame of video.

When the probe pulse starts within the active video area, an optional marker indicating the starting
point of the pulse can be added to the video as a reference. When present, the marker is non-destruc­tive (i.e. doesn’t trash the underling test image). The marker can be toggled ON and OFF, while the
probe UI is displayed, using the Image Step button.

Remote (Computer) Operation of Probe Pulse Feature

The probe pulse can be controlled by sending commands to the generator via either its serial or GPIB
(IEEE-488) ports. The commands are:

Probe Sync Pulse Gate - PSPG
0 = Disable Pulse, 1 = Enable Pulse

Probe Sync Pulse Polarity - PSPP
0 = Active Low Pulse, 1 = Active High Pulse

Probe Sync Pulse Width - PSPW
In pixels, sets the width of the active portion of the probe pulse.
Limits: 0 < PSPW < (HTOT-1)

Probe Sync Horizontal Delay PSHD
In pixels, locates the leading edge of the probe pulse on the line relative to the leading edge of the
horizontal sync pulse.
Limits: 0 <= PSHD < (HTOT-PSPW-1)

Probe Sync Vertical Delay PSVD
In lines, assigns in which scan line the probe pulse occurs relative to the start of the vertical blanking
interval (for the first field of video in the case of interlaced operation).
Limits: 0 <= PSVD < (VTOT-1)

The default values at the power up are: PSPG = 0, PSPP = 1, PSPW = 160, PSHD = 0 and PSVD = 0.
The commands do not affect the probe pulse output until an FTMU command is issued. Multiple

commands can be sent in one command string, using semicolons to separate the commands. No part of
the input string is acted upon until a carriage return ends the input. The generator returns a R>\ prompt

Reinitializing Memory

(1) Momentarily hold down both buttons
for about 5 seconds during power-up to
enable re-initialization.

Reinitializing the generator’s
memory erases all user created

data and sets all video ampli­tude calibration factors to 0.000.
This will disable the video
outputs until self calibration is
performed.

Exits re-initialization

any changes

Re-initializes all user
memory locations to

Self Calibration of Analog Output Levels

The video output module on the Model 822S
has a built-in precision voltage reference and
comparator. They permit the video output
levels to be easily and accurately self
calibrated using just test cables and 50 ohm
terminators. The cables and terminators are
not supplied as a standard accessories with
the 822S.

1) The easiest way to start the procedure is to use the
button combination shown during power up.

Momentarily hold down all three video gating buttons
for about 5 seconds during power-up to start self­calibration.

Self Calibration of Analog Output Levels (continued)

You can also start the procedure by sending the
following command string to the generator’s comm port
while the unit is running:

AVCM 1; fmtu <carriage return>

Details on the connections can be found on a later
page.

2) The LCD will display a prompt asking you to make
the connections for calibration.

5) Connect the 50 Ohm feedthrough terminators and
two 50 Ohm coaxial cables as shown. The calibration
routine can compensate for small losses in the cables
normally with the generator if they are used for the self
calibration connections.

4) Rotate the Image knob to start the self calibration
operation.

5) Self calibration takes about one minute per module.
The LCD will show a progress report during this time.
Any messages indicating that the unit could not bring
an adjustment within calibration may indicate a
problem with your connections or with the module
itself.
