Emulation
This part of Chapter 4 describes the 8662A and 8663A emulation mode. When in this
mode, the Instrument responds to 8662/8663A IEEE bus commands instead of the SCPI
bus commands. Also, only functions available on the Instrument are emulated. For
example, the Instrument does not provide simultaneous AM and FM modulation like the
8662/8663A, so this feature is not emulated.
Note
The Instrument does not store the state of the last 8662A/8663A bus setting.
Therefore, if the user manually switches the Instrument from remote to
local, makes a setting change, and then switches back to remote, the
Instrument may not be in the state the controlling computer expects when it
resumes control.
Preparing the Instrument for Remote 8662/8663A Emulation
Use the following procedure to prepare the Instrument for 8662A emulation:
1. Press

on the front panel.
2. Press the GPIB Preferences soft key to bring up the GPIB Personality screen.
3. Use the

amplitude.
The output amplitude adjustment provides the opportunity to reduce (limit) the
output power to match that of the 8662A/8663A, and avoid applying excessive
power to the unit under test.
