Chapter 4, Description of Fields

Fields

GPIB Example

“STATus:CDMA2:EVENt?”

queries the CDMA_2 status event register. If bit 5 is set, the last gated power test passed. If bit 4 is set, the last gated power test failed.

FER

This field displays the current frame error rate (FER) measured by the Test Set. A Service Option 2 (mobile station data loopback) call must be connected before running an FER test.

A measurement result will be displayed at the end of a test if Display Interim Results is No. (The Passed, Failed, or Max Frames annunciator will light when a test is done.) Measurement results will be displayed continuously, and queries will be returned based on interim results if Display Interim Results is Yes.

GPIB Example

“DISP CRXT;MEASure:CDManalyzer:FERasure?“

queries the currently displayed FER measurement result.

Operating Considerations

To measure FER, the mobile station must be on a traffic channel and looping data back. The Connected and Svc Opt 2 annunciators are lit when the mobile station is looping data back.

The CDMA Status Register provides status bits for the Passed, Failed, and Max

Frames Test Status indicators.
