Addressing and Initializing the Instrument
The Keysight 86120B’s GPIB address is configured at the factory to a value of 20.
You must set the output and input functions of your programming language to send
the commands to this address.
To change the GPIB address
1 Press the Setup key.
2 Press MORE twice, then GPIB .
3 Use the and softkeys to change the GPIB address.
4 Press RETURN .
Remote mode and front-panel lockout
Whenever the instrument is controlled by a computer, the
Remote
message is dis-
played on the instrument’s screen and the softkey menu is blanked except for the
LOCAL softkey. This softkey can be pressed by the user to restore front panel con-
trol of the instrument.
You can specify a local lockout mode that prevents the
LOCAL softkey from being
displayed. If the instrument is in local lockout mode, all the softkeys may be
blanked. For example, if the instrument is first placed in local lockout mode and
then placed in remote mode, no softkeys are displayed.
Consult the documentation for your programming environment to determine which
commands are used to put an instrument in the remote and local lockout modes.
These are not Keysight 86120B commands; they control GPIB control lines and do
not send any characters to the Keysight 86120B.
Initialize the instrument at start of every program
It is good practice to initialize the instrument at the start of every program. This
ensures that the bus and all appropriate interfaces are in a known state. HP BASIC
provides a CLEAR command which clears the interface buffer and also resets the
instrument’s parser. (The parser is the program that reads the instructions that you
send.) Whenever the instrument is under remote programming control, it should be
