Executing Self-Test and Leak Test

Executing Self-Test

To Execute Self-Test using External Controller

You can execute Self-Test from an external controller by using SCPI commands 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.

Requirements

•Controller

•GPIB Cable

•Relay Test Adapter

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

SCPI Commands for Self-Test

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.
