Test Descriptions

TEST_22 - OTA No Audio Functional

Description

This test contains a collection of tests designed to provide a quick

evaluation of the MSUT without the need to make audio connections

from the MSUT to the test system. The following tests are included:

TEST_21 - CPA Origination

TEST_03 - TXA Frequency Error

TEST_04 - TXA RF Power Output

TEST_08 - TXA Signaling Tone/DST

TEST_10 - TXA SAT/DSAT

TEST_11 - TXA RVC Data Deviation

TEST_27 - CPA Hook Flash

RXA Tones Functional

RXA SINAD Functional

TXA Microphone Functional

The first seven tests in the above list are described individually in this

chapter. The final three tests are available only as part of this test and

they work as follows:

• When prompted, the operator is required to listen for tones from the

receiver and then select whether the test passed or failed. The

pass/fail decision is qualitative, and is usually based on whether the

tones are heard clearly.

• When prompted, the operator is required to listen to a 1 kHz tone

that is modulated on a low power level carrier signal. The power

level of the carrier signal is set by parameter 29. RXA RF Level for

SINAD (dBm). The operator must select whether the test passed or

failed. The pass/fail decision is qualitative and is usually based on

whether the 1 kHz tone could be heard adequately among the static.

• The operator is required to whistle into the transmitter, to observe

the deviation on the test system, and then select whether the test

passed or failed. The pass/fail decision is qualitative, and is usually

based on whether the change in deviation corresponds with the

amplitude of the whistle into the transmitter.
