GPIB Configuration
The GPIB interface requires the optional GPIB interface board and uses a standard IEEE-488 cable to connect to
the computer.
Each device on the GPIB (IEEE-488) interface must have a unique whole number address between 0 and 30 (default
5). Your computer’s GPIB interface card address must not conflict with any instrument on the interface bus. To
change the GPIB address:
Front Panel
SCPI Command
[Menu] > System > IO > GPIB
Use the numeric keypad to enter a value from 0 to 30. Then press [Enter].
