Equivalent Softkey: CPL RBW OM OFF.
Option Required: Option 105. Option 101 is recommended.
Preset Value: Uncoupled.
Related Commands: GDRVPWID, GDRVVBW, GDRVST.
Example
OUTPUT 718;“MOV GDRVRBW,l;” Couples the resolution bandwidth to the pulse width.
Description
Before coupling the resolution bandwidth to the pulse width, you should enter the pulse width
into GDRVPWID. Coupling the resolution bandwidth to the pulse width updates the trace
display in the active window. If the resolution bandwidth and the pulse width are uncoupled,
the setting of the resolution bandwidth does not change.
The resolution bandwidth is at least three times Pu,sekadth when coupled. The resolution
bandwidth is updated to the coupled value when the window is next active.
You can execute the GDRVRBW command two different ways. You can either execute the
GDRVRBW command directly (for example, “GDRVRBW 1; I’) or use the MOV command to move
the 1 or 0 into the GDRVRBW command (for example, “MOV GDRVRBW, 1; ‘I). If you use the MOV
command, no text is displayed in the active function area during command execution.
The GDRVRBW 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.
