Description
Unlike ENTER REF EDGE , GDRVREFE does not make the marker function active or display the
Enter REF EDGE softkeys.
Once you enter a value into GDRVREFE, that value is retained until you change it, or execute
DISPOSE ALL. Pressing @?Z’Z7] or turning the spectrum analyzer off does not change the
value of GDRVREFE.
You can execute the GDRVREFE command two different ways. You can either execute the
GDRVREFE command directly (for example, "GDRVREFE 1MS ; ‘I) or use the MOV command
to move the value into the GDRVREFE command (for example, “MOV GDRVREFE, 1MS; ‘I). If
you use the MOV command, no text is displayed in the active function area during command
execution.
The GDRVREFE 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.
