Description
You can execute the GDRVGLEN command two different ways. You can either execute the
GDRVGLEN command directly (for example, "GDRVGLEN 1MS ; ‘I) or use the MOV command to
move the value for the gate length delay into the GDRVGLEN command (for example, “MOV
GDRVGLEN , 1MS ; ‘I). If you use the MOV command, no text is displayed in the active function
area during command execution.
The GDRVGLEN 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.
