Errors at Runtime

Problem:

When it is first run, the Software checks to see that all required elements of a CDMA/PCS Test System are present. If it does not find a CDMA Cellular Adapter or a PCS Interface, it will report the following errors:

HP-IB Command not accepted. Option not installed.:

This error will be reported if the Software cannot “find” the CDMA Cellular Adapter as an installed option on the Test Set.

Solution:

1Make sure that your are using either the HP 83203B or HP 83205A CDMA Cellular Adapter in your Test System.

2Verify that you have supplied the Cellular Adapter with AC power. The front-panel PWR light should be illuminated.

3If the unit is powered on and you still get this message, you will need to check the rear- panel connections between the Test Set and Cellular Adapter, especially the CONTROL I/O cable between the two units. Refer to the Installation chapter of the Cellular Adapter’s manual for connections.

Verify PCS Interface is connected and on. Retry?:

This error will be reported if the Software cannot “find” the HP 83236B PCS Interface on the HP-IB bus.

Solution:

1Verify that you have supplied the PCS Interface with AC power and that the POWER switch is on. The front-panel POWER light should be illuminated.

2If the unit is powered on and you still get this message, check the rear-panel HP-IB connection between the Test Set and Cellular Adapter.

3Confirm that the rear-panel HP-IB Address Selector switch is set to “HP-IB” ( not “Ser”). If the switch is in the wrong position, correct it and cycle power on the PCS Interface.
