CDMA carrier frequency verification

You will verify the frequency of the transmitted CDMA carrier signal to

be within 0.05 ppm.

Code domain power noise, pilot power, and total power

You will verify that the code domain noise floor of all unused Walsh

codes within the CDMA spectrum measures < –27 dB (with respect to

total power). Pilot power will be verified to measure –7.04 dB +/–0.5

dB (with respect to standard test patterns). Total power will be verified

to measure +2/–4 dB (with respect to CDF specific file parameters).

BTS frequency accuracy

BTS frequency accuracy can be verified manually during normal

operation by monitoring the 19.6608 MHz reference (19 MHz) from the

Diagnostic Access Area. A frequency counter with an accuracy of +/–

0.005 ppm can be used to check the BTS frequency accuracy.

RX Test Objective

The following test will verify the RX antenna path(s).

All tests will be performed using the communication test set.

Measurements will be via the Antenna A and Antenna B connectors.

RX Tests

The following RX test will be performed to verify the CDMA Reverse

Link.

BTS RX sensitivity/frame erasure rate

The default test verifies the BTS sensitivity on all Traffic Channel

elements (fullrate at 1% FER) at an RF input level of –117 dBm on the

RX antenna path.

There are no pass/fail criteria associated with FER readings

taken at level below –117 dBm; other than to verify that

the FER measurement reflects changes in RX input signal

level.
