3.12 List Sweep Measurement (Remote Only)
3.12 List Sweep Measurement (Remote Only)
List Sweep can be selected using the front panel key or the remote command.
Measurement setup control is only available remotely. While in the List Sweep
measurement, the screen is blanked, with a message “Executing List Sweep
measurement from Remote Control port”.
To exit List Sweep you can select another measurement (press Mode/Meas for the
Mode/Meas/View dialog) or press the Mode Preset key, which will return you to the
Swept SA measurement.
Since List Sweep is a Remote only measurement, you may want to lock out the front
panel keys to avoid having key presses interfere with the measurement. There are
two ways to lock out the front panel keys. Accessing the instrument over GPIB
(IEEE-488) puts it in remote operation, or you can send the :SYSTem:KLOCk ON
command.
