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.
Programming commands address specific modules and must conform to the
proper syntax to achieve the desired result.
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 used by this module are shared by several modules and will
be accepted without a reported error.
2. Enable the module using the command. The output state
of the module must be enabled before test-signal parameters can be changed.
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.
BG1 Black Burst 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 arguments 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 TG 2000 generator
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.

Glossary
Black Burst
Also called “color black,” black burst is a composite video signal consisting
of all horizontal and vertical synchronization information and burst.
Typically used as the house reference synchronization signal in television
facilities.
Burst
A small reference packet of the subcarrier sine wave sent on every line of
video. Since the carrier is suppressed, this phase and frequency reference is
required for synchronous demodulation of the color difference signals in the
receiver.
Color Frame Reference Flag
The color frame reference flag is the white flag that can be selected to be on
the black burst signals of the BG1 module. The flag occurs on field 1,
line 10 for the NTSC and NTSC without setup test signals. The flag occurs
on field 1, line 7 for the PAL test signals.
Composite Video
A single video signal containing all of the necessary information to
reproduce a color picture. Created by adding quadrature amplitude modulated U and V to the luminance signal.
Frame
A frame (sometimes called a “picture”) contains all the information required
for a complete picture. For interlaced scan systems, there are two fields in a
frame.
NTSC
National Television System Committee. The organization that developed the
television standard currently in use in the United States, Canada and Japan.
Now generally used to refer to that standard.
PAL
Phase Alternate Line. Refers to one of the television systems used in Europe
and many other parts of the world. The phase of one of the color difference
signals alternates from line to line to help cancel out phase errors.
SCPI
Standard Commands for Programmable Instruments. SCPI is a standard that
provides guidelines for remote programming of instruments. These
guidelines provide a consistent programming environment for instrument
control and data transfer.
BG1 Black Burst Generator User Manual
Glossary–1
Glossary
Signal Set
A set of industry standard test signals provided by Tektronix on floppy disks.
Soft key
An item on the display that changes state or initiates an action when you
touch it on screen. You use soft keys to select test signals or enter a file
name.
Termination
In order to accurately send a signal through a transmission line, there must
be an impedance at the end that matches the impedance of the source and of
the line itself. Amplitude errors and reflections will otherwise result. Video
is a 75 W system, so a 75 W terminator must be put at the end of the signal
path.
Time Zero
Time zero is the reference time for the TG 2000 mainframe and is the timing
of the outputs of the BG1 module. When you adjust the Genlock module
timing, you are adjusting the time zero reference. When you adjust the
timing of an individual module, the timing of that module is offset from the
time zero reference.
