2-26 Fully Coded 3GPP W-CDMA Personality User’s and Programming Guide

Using Functions ESG Family Signal Generators

3GPP W-CDMA User Equipment Performance Tests Option 200

At this point, the controller must configure the UE into a test mode. With the UE

operating in test mode, the controller assigns the UE a dedicated physical channel on

which to receive and demodulate the transmitted data.

3. Measure the Bit Error Ratio (BER) of the data received by the UE on RMC 12.2 kbps

(25.101 V3.3).

The controller (or BER test platform) is measuring the bit error ratio of the UE exposed

to Î

(the RF output of ESG 1) at an arbitrary amplitude. This process verifies that the

BER of the UE is within specification prior to decreasing the amplitude of Î

4. In Table 2-12, record the measured BER value in the column titled, “Verification BER

Value.”

5. Compare the measured BER value in the column titled, “Verification BER Value” with

the limits from the column titled, “Specification Limitations.”

• If the measured value is within the limits, continue to subsection 2.

• If the measured value is outside the limits, determine the cause of failure and repair

the UE. After repair, return to Step 1 of this subsection.

Subsection 2. Reference Sensitivity Level Measurement

Complete the following steps to perform a reference sensitivity level measurement on your

UE.

1. Decrease the amplitude level of Î

In accordance with the 3GPP W-CDMA RF specification, decrease the amplitude of Î

−

106.7 dBm.

On ESG 1: Press

Amplitude > −

106.7

> dBm.

2. Measure the BER of the data received by the UE on RMC 12.2 kbps (25.101 V3.3) at the

decreased amplitude.

The controller (or BER test platform) is measuring the bit error ratio of the UE with an

amplitude of

−

106.7 dBm.

3. In Table 2-12, record the measured BER value in the column titled, “Minimum

Amplitude BER Value.”

4. Compare the recorded BER value in the column titled, “Minimum Amplitude BER

Value” to the allowable values in the column titled, “Specification Limitations” and

record the status of the UE as PASS or FAIL in the column titled, “PASS/FAIL Status.”
