AVG1 Analog Video Generator User Manual
Getting Started
Getting Started
The AVG1 Analog Video Generator module is designed to be installed in the
TG 2000 Signal Generation Platform.
The module is a high accuracy, multiformat analog video test signal generator.
The signal generation architecture is 12-bit, 27 MHz component with digital
modulation for composite signals. This ensures high accuracy, distortion free
signals within a 6 MHz video bandwidth.
This module provides three channel outputs and one trigger output. The trigger
output can be used to trigger other video equipment or an oscilloscope.
The module can generate signals in these component and composite formats:
H NTSC
H PAL
H PAL-D
H PAL-M
H PAL-N
You can create other formats with the SDP2000 program. However, the output
reconstruction filters are optimized for a 27 MHz sampling frequency.
To adjust the amplitude or time base offset parameters, follow the procedure for
Video Parameters on page 2--11. Several amplitude parameters of the signal can
be adjusted, such as luminance amplitude and chrominance gain.
The underlying time base used to generate signals can also be adjusted. When
this parameter is adjusted, it adjusts every component of the active video signal,
such as line length, subcarrier frequency if applicable, and rise time. The signal
also becomes unframed; it has no phase relationship with the genlock input
(AGL1 Generator module). Two modules with the same time base offset value
are not necessarily framed together.

Functional Check
Getting Started
For this procedure, you will need a television monitor, a 75 Ω coaxial cable, and
a75Ω termination.
To determine if the module is operating correctly, follow these steps:
1. If the module is not installed into the platform, use the installation proce-
dures on page C--2.
2. Power on the platform. The platform runs a self test on all modules.
3. To determine if the self test was successful, push the Module button. Check
the display for the icon that represents the module you are inspecting. If the
module does not appear, refer to Troubleshooting in the AVG1 Analog Video
Generator Service Manual.
4. If your module was ordered separately and you installed it in the platform,
and you do not have another AVG1 Generator module already installed in the
platform, install signal sets using the procedures on page C--6.
5. Wait 20 minutes for the instrument to warm up at nominal ambient
temperature. (Signal amplitude and DC offset may vary slightly over a
range of temperatures.)
6. Perform self calibration as follows:
a. Terminate the three rear-panel signal outputs.
b. Push the Utilities button and then touch Module Self Cal.
NOTE. The original calibration file will be replaced by the new one.
c. Touch the Self Cal icon for the module you are testing
d. Touch Start Cal. The Self Cal takes 2 to 5 minutes depending on the
module. An error message indicates a failed calibration. If the Self Cal
fails, contact your Tektronix Representative for assistance.
e. When the Self Cal is successful, proceed to step 7.
7. Select a signal set and output signal that are compatible with your monitor. A
composite signal is preferred because it tests more of the module’s hardware.
8. Connect the rear-panel Output 1 connector to the television monitor’s input.
9. Configure the channel outputs for composite as follows:
a. Push the Test Signals front-panel button.
b. Touch Module Parameters.
AVG1 Analog Video Generator User Manual
1- 3
Getting Started
c. Touch Output Config.
d. Select Composite All Channels.
10. Adjust your monitor to view the signal. Check that the signal appears as
expected. For example, if you selected a color bar signal output, check for a
color bar signal on the monitor display.
11. Move the output cable to each of the channel output connectors in turn to
ensure that the appropriate signal appears.
12. Move the cable back to Output 1.
13. Select a different test signal in the same signal set and check that the
displayed signal changes. You only need to do this on Output 1.

Modulated Signals
This module has four BNC connectors on the rear panel: one Trigger Out and
three channel outputs. The channel outputs can be configured as shown in
Table 2--1. To configure the outputs, refer to Configure the Outputs on page C--9.
Table 2- 1: AVG1 Output Configurations
Connector GBR Y, B-Y, R-Y Hardware modulated Software modulated
Channel 1 G Y Y or Composite Composite 1
Channel 2 B B-Y C or Composite Composite 2
Channel 3 R R-Y Composite Composite 3
There are two methods of signal generation for composite signals: hardware
modulation and software modulation. Hardware modulated signals are preferred
when the lowest amount of differential phase and differential gain is required.
Hardware modulated signals use less memory than software modulated signals;
and signal parameter adjustments are more complete and responsive.
Chroma quantization makes differential phase and differential gain measurements more difficult when using modulated ramp, modulated 5 step, and
modulated 10 step signals. To minimize this effect, adjust the Chroma Gain
Video Parameter to 102.0%. Refer to page 2--11.
Online Help
Software modulated signals are preferred when three different signals are
supplied by the module at one time. PAL is not supported in this mode, because
of the 25 Hz offset.
Push the front-panel HELP button to display a help window. The help window
describes the window you were using when you pushed HELP.

Syntax and Commands
Syntax
Programming Model
This section contains information on the Standard Commands for Programmable
Instruments (SCPI) and the programming structure you can use to program your
module.
Specific conditions must exist before programming commands will affect the test
signal generated by a module.
Addressing Module Test
Signals
Command Arguments
The following two steps must be performed before the test module will respond
to signal parameter commands.
1. Select the module to be addressed before executing any commands. Many of
the commands are shared by several modules and will be accepted without a
reported error.
2. Enable the module using the :OUTPut:STATe ON command. You must
enable the output state of the module before you change the test signal
parameters.
Many commands will accept either string or numeric arguments. For example: a
Boolean argument can either be “1” or “ON“.
Signal parameter commands that have a :STEP node can accept either a numeric
value or they can accept a string argument that refers to the :STEP increment.
Signal parameter commands with a :STEP node will accept the following strings
in addition to a numeric value:
UP. Use this argument to increase the parameter value one increment as defined
by the :STEP value.
DOWN. Use this argument to decrease the parameter value one increment as
defined by the :STEP value.
AVG1 Analog Video Generator User Manual
3- 1
Syntax
MINimum. Use this argument to set the parameter value to the minimum
acceptable value.
MAXimum. Use this argument to set the parameter value to the maximum
acceptable value.
DEFault. Use this argument to set the parameter value to the default value.
Argument Example
The following example demonstrates the effect of each argument used with a
step value.
1. :INSTrument:SELect ”AVG1:#” selects the analog video generator module
located in the slot number indicated by the “#” symbol.
2. :OUTPut:STATe ON enables the module and displays the loaded test signal.
3. :OUTPut:CIRCle:STATe ON displays a circle on the video display.
NOTE. :OUTPut:CIRCle:DIAMeter uses an argument that is the percent of
picture height.
4. :OUTPut:CIRCle:DIAMeter DEFault sets the circle diameter to 90 percent
of the screen height.
5. :OUTPut:CIRCle:DIAMeter:STEP 10 sets the step increment to 10 percent.
6. :OUTPut:CIRCle:DIAMeter DOWN changes the circle diameter to
80 percent of the screen height.
7. :OUTPut:CIRCle:DIAMeter 50 changes the circle diameter to 50 percent of
the screen height.
3- 2
8. :OUTPut:CIRCle:DIAMeter MAXimum changes the circle diameter to
100 percent of the screen height.
9. :OUTPut:CIRCle:DIAMeter MINimum changes the circle diameter to
0 percent of the screen height.
10. :OUTPut:CIRCle:DIAMeter UP changes the circle diameter to 10 percent of
the screen height.

SCPI Commands and Queries
SCPI is a standard created by a consortium that provides guidelines for remote
programming of instruments. These guidelines provide a consistent programming environment for instrument control and data transfer. This environment
uses defined programming messages, instrument responses, and data format
across all SCPI instruments, regardless of manufacturer. The AVG1 Generator
module uses a command language based on the SCPI standard.
The SCPI language is based on a hierarchical or tree structure (see Figure 3--1)
that represents a subsystem. The top level of the tree is the root node; it is
followed by one or more lower-level nodes.

You can create commands and queries from these subsystem hierarchy trees.
Commands specify actions for the instrument to perform. Queries return
measurement data and information about parameter settings.

status and events, refer to the TG 2000 Signal Generation Platform User
Manual.
