Description
When the pulse repetition interval is entered, the approximate gate trigger position will be
indicated on screen by either a
“T”for
a positive trigger, or a
“I”
for a negative trigger. Unlike
EhlTER
PRI , GDRVPRI does not make the marker function active or display the Pulse
Param
softkeys.
Once you enter a value into GDRVPRI, that value is retained until you change it, or execute
DISPOSE ALL. Pressing
(j-1
or turning
the
spectrum analyzer off does not change the
value of GDRVPRI.
You can execute the GDRVPRI command two different ways. You can either execute the
GDRVPRI command directly (for example,
"GDRVPRI
1MS
;
I’)
or use the MOV command to
move
the value for the time delay into the GDRVPRI command (for example,
"MOV
GDRVPRI ,
1MS
;
I').
If you use the MOV command, no text is displayed in the active function area during command
execution.
The GDRVPRI 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.
