To Check the GPIB
Procedure
Perform the E5052B performance test program. If the controller cannot detect the E5052B,
the problem seems in the A24 GPIB card or the connection of the GPIB cable.
To Check the 24-bit I/O port
Procedure
This check is performed using a handler I/O test kit (p/n E5070-65001) as a substitute for
the handler.
Step 1. Connect the flat cable of handler I/O test kit to “J2” connector of the kit.
Step 2. Connect the cable of the kit to the 24-bit I/O port connector on the rear panel.
Step 3. Check the 24-bit I/O port by executing “24bitI-Otest.vba”.
NOTE The program “24bitI-Otest.vba” can be downloaded from the Keysight Technologies
website to USB Mass Strage Device.
Step 4. If the check failed, a failure in the A23 24-bit I/O board is suspected.
