Optimizing Performance
Creating and Applying User Flatness Correction
Returning the Signal Generator to GPIB Listener Mode
During the user flatness correction process, the power meter is slaved to the
signal generator via GPIB, and no other controllers are allowed on the GPIB
interface. The signal generator operates in GPIB talker mode, as a device
controller for the power meter. In this operating mode, it cannot receive SCPI
commands via GPIB.
If the signal generator is to be interfaced to a remote controller after
performing the user flatness correction, its GPIB controller mode must be
changed from GPIB talker to GPIB listener.
If an RF carrier has been previously configured, you must save the present
instrument state before returning the signal generator to GPIB listener mode.
1.
Save your instrument state to the instrument state register.
For instructions, see
“Saving an Instrument State” on page 73
2.
Press
Amplitude > More (1 of 2) > User Flatness > GPIB Listener Mode
.
This presets the signal generator and returns it to GPIB listener mode. The
signal generator can now receive remote commands executed by a remote
controller connected to the GPIB interface.
3.
Recall your instrument state from the instrument state register.
