Troubleshooting an E1438 ADC module

This section provides information on troubleshooting an E1438 ADC module.

To verify the E1438 module using the self test:

1. If you have either the Vector Signal Analyzer or Spectrum Analyzer running,
close the application.
2. Click Start > (All) Programs > Vxipnp > Age1438 > E1438 Front Panel.
3. If the factory default address has been changed you must enter it into the dialog
box that will be presented.
There are two ways to find the E1438 address:
a. Click on the Agilent IO Libraries Suite Control icon and click VXI
Resource Manager > Edit Resources, highlight Add/delete symbolic
names of VXI devices, and click RM Output. The LADD column in the
VXI device table lists the logical address for each module.
b. Open the Vector Signal Analyzer or Spectrum Analyzer, click Utilities >
Hardware and the ADC tab for the module. The logical address is listed in
the first column with the VXI mainframe number.
4. On the menu bar of the front panel program select Control > Self Test.
If errors are reported, then the E1438 module is faulty.
5. Repeat this procedure for a second E1438 if necessary.
The E1438 front panel test always looks for a module at logical address 192. If
it finds one, it automatically opens the soft front panel for that module. To test
another E1438 module, power-off the mainframe and pull the module with
address 192 out of the mainframe (you don't have to remove the module
completely--just slide it forward an inch or so). Repeat steps 1-4 above.
