To Check The Gpib; To Check The 24-Bit I/O Port; To Check The Ref Oven; To Check The Usb (Usbtmc) Interface Card - Agilent Technologies E5052A Service Manual

To Check the GPIB

Procedure
Perform the E5052A performance test program. If the controller cannot detect the E5052A,
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 Agilent Technologies web
site to a floppy disk using your computer's FDD.
Step 4. If the check failed, a failure in the A25 24-bit I/O board is suspected.

To Check the Ref Oven

Procedure
This check is performed using a frequency counter and a power meter.
Step 1. Connect the frequency counter to the Ref Oven connector, and then verify that the
frequency value is 10 MHz ± 1 Hz.
Step 2. Connect the power meter to the Ref Oven connector, and then verify that the power value is
2.5dBm ±3dB.
Step 3. If the check failed, a failure in the A11 10 MHz Oven is suspected.

To Check the USB (USBTMC) Interface Card

Procedure
Connect the USB cable between the controller PC and the E5052A. Turn the controller PC
on. If the E5052A cannot detect the controller PC, the problem seems in the USB
(USBTMC) Interface Card or the A20 digital motherboard is suspected.
