Selecting the Signal Generator’s GPIB Address
The signal generator’s GPIB address is set to 19 at the factory. You can view and change 
the address by pressing 
Utility > GPIB/RS-232 > GPIB Address. The current GPIB address is 
displayed in the softkey label and also in the active entry area. To change the address, 
enter a new value using the numeric keypad and then press 
Enter, or rotate the front panel 
knob. The acceptable range of addresses is 0 through 30.
The GPIB address is a persistent state; it is not affected by an instrument preset or by a 
power cycle.
Selecting the Signal Generator’s Programming Language
The default programming language for the signal generator is Standard Commands for 
Programmable Instruments (SCPI). You can change this language selection by pressing 
Utility > GPIB/RS-232 > Remote Language. The Remote Language menu allows you to select 
between Agilent 8656/57-compatible language, Agilent 8648-compatible language, and 
SCPI language. If you have Option UN8, the Remote Language menu allows you to select 
between Agilent 8656/57-compatible language, Agilent 8657D language (NADC digital 
modulation capability), Agilent 8657D language (PDC digital modulation capability), and 
Agilent 8657J (PHS digital modulation capability). Press the softkey for the selection that 
you desire.
You can also change the language selection by sending the appropriate command over 
GPIB. Refer to the programming guide for instructions for changing the language over 
GPIB.
You can set the signal generator to default to a selected language as a persistent state 
(remains unchanged after an instrument preset or power cycle). Press 
Utility > 
Power On/Preset > Preset Language. The Preset Language menu allow you to select between 
SCPI, the Agilent 8656/57-compatible programming languages, and 
Agilent 8648-compatible language. Press the softkey for the selection that you desire.
