Description
Before executing GDRVGT, you should do the following:
1. Ensure there is a trigger pulse connected to the GATE TRIGGER INPUT connector on the
rear panel of spectrum analyzer. The gate utility functions do not work if there is not a
trigger input.
2. Ensure that the GATE OUTPUT connector and the EXT TRIG INPUT connector are
connected together.
If the time window is the active window, turning on the gate with GDRVGT makes the
frequency window the active window. The GDRVGT command is a gate utility function (see
“GDRVUTIL” for more information about
the
gate utility functions). Executing a gate utility
command without Option 105 installed in the spectrum analyzer generates the
COMMAND ERROR:
message and an SRQ 140.
You can execute the GDRVGT command two different ways. You can either execute the
GDRVGT command directly (for example,
"GDRVGT 1;
I’)
or use the MOV command to move
the 1 or 0 into the GDRVGT command (for example,
"MOV
GDRVGT,l;").
If you use the MOV
command, no text is displayed in the active function area during command execution.
