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.
