N67xx DUT Power Supply Installation 1-25

Connecting the Power and GPIB Cables

Plug the DUT Power Supply’s power cord into the nearest power outlet box, with

the proper voltage, in the testhead. Each outlet box is marked with its voltage.

Connect 0.5-meter GPIB cables (10833D) to existing supplies. The DUT power

supplies handshake faster than most other devices on the bus. If they are cabled

directly to the controller, the glitches they generate can cause GPIB timeout errors.

Figure 1-13 Connecting the GPIB cables

The DUT Power Supply GPIB cables must be at the end of

the GPIB cable string. Figure 1-13 shows how to connect

the GPIB cables, including when an optional instrument bay

is used.

Programming the GPIB Address on Power Supplies

Table 1-8 shows the valid GPIB addresses for DUT power supplies. Be sure not to

duplicate a GPIB address if making changes.

Set the GPIB address from the front panel of the DUT power supply.

1 Press ADDR and enter the address.

2 Press ENTER.
