To Execute Self-Test using External Controller

You can execute Self-T est from an external contro ller by u sing SCPI comman ds in a

program.

This section describes the requirements, SCPI commands, and a sample program for

Self-Test execution from an external controller. For details about the SCPI

commands, refer to Chapter 7.

• Controller

• GPIB Cable

• Relay Test Adapter

• BNC Short Caps (3 caps are furnished with each E5255A)

Table 3-2 shows the SCPI commands used to execute Self-Test. Keyword of the

SCPI command first level is :DIAG.

The :DIAG commands ignore the E5250A channel configuration mode (NORMAL

or AUTO).

For :DIAG commands that require a card number, you specify 1, 2, 3, 4, or ALL.

If the Fail LED turns on after executing the Self-Test, the E5250A or modules may

be defective. Contact your nearest Agilent Technologies Service Center.

NOTE Before executing Relay Test, be careful about following:

• Attach the Relay Test Adapter to the E5250A input connectors. Refer to Figure

3-1. Then set the switch on the adapter to the Relay Test position.

• Open all outputs of the plug-in cards as follows: If cable is connected to output

connector of plug-in card, open output at DUT end of cable. If end of cable is

Kelvin connection, disconnect the cable or make non-Kelvin connection at end

of cable.

• For each E5255A installed in the E5250A, connect a BNC short cap to each

E5255A BIAS INPUT connector.
