GPIB PORT SETUP

The following paragraphs describe the how to configure the GPIB port.

3.6.3.1.1 CHANGING THE GPIB ADDRESS

The default address is 6. To change the GPIB address use the SYST:COMM:GPIB:ADDR com-
mand (PAR B.122). To configure a particular GPIB address to implemented upon power-up,
refer to PAR. 3.3.2.2).

3.6.3.1.2 CONFIGURE DEVICE CLEAR (DCL) CONTROL

The device clear (DCL) and selected device clear can be set to operate in two modes. In the
MATE mode (DCL1), when the device clear is received, the output of the power supply is set to
zero volts. In the SCPI mode (DCL0) sending DCL or selected DCL has no effect on output volt-
age and current as required by IEEE specification 488.2. The factory default value is SCPI
mode (DCL0) (see PAR. B.144).
