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) only. This process verifies that the BER of the UE is

within specification prior to the introduction of the spurious response stimulus.

4. In Table 2-35, 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. Spurious Response Measurements

Complete the following steps to make spurious response measurements on your UE.

Figure 2-11 Spurious Response Measurements Equipment Setup

1. Connect the additional equipment to the test system as shown in Figure 2-11.

a. Connect the RF output of ESG 1 to one input of the signal combiner.

b. Connect the RF output of ESG 2 to one input of the signal combiner.

c. Connect the signal combiner output to the RF input of the UE.
