Computer Connections

The dc source can be controlled through an GPIB interface. Agilent 66111A and 66311B/D units can also be controlled through an RS-232 interface.

GPIB Interface

Follow the GPIB card manufacturer’s directions for card installation and software driver setup.

Each dc source has its own GPIB bus address, which can be set using the front panel Address key as described in chapter 5. GPIB address data is stored in non-volatile memory. The dc source is shipped with its GPIB address set to 5.
