1. Save your instrument state to the For instructions, see Saving an Instrument State
instrument state register. in example 6 on page 20.
2. Press [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.
For instructions, see “Recalling an Instrument
State” in example 6 on page 20.
Recalling and applying a user
flatness correction array
Before performing the steps in this
section, complete Creating a User
Flatness Correction Array.
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 connections are
allowed on the GPIB interface. The
signal generator operates in GPIB
talker mode, as a device controller
for the power meter. In this operat-
ing mode, it cannot receive SCPI
commands via GPIB.
CAUTION If the signal generator is
interfaced to a remote controller
after performing the user flatness
correction, its GPIB controller mode
must be changed from GPIB talker
to GPIB listener. This is accom-
plished by presetting the signal
generator. If an RF carrier has
been previously configured, you
must save the present instrument
state before returning the signal
generator to GPIB listener mode.
