To Configure the Remote Interface
The instrument can communicate with a computer over GPIB or RS-232
interface. Only one interface can be used at a time. When shipped from
the factory, the GPIB interface is selected and its address is set to “9”.
Note The RS-232 interface can be configured and used only in SCPI mode.
GPIB Interface
Each device on the GPIB interface must have a unique address.
•
When shipped from the factory, the GPIB interface is selected and its
address is set to “9”. The GPIB address of the instrument can be set to
any value between 0 and 30.
•
The GPIB address is stored in non-volatile memory, and does not
change when the instrument is turned off or reset.
