3GPP W-CDMA Base Station Performance Testing Option 200

Example Test Procedure

Follow this example procedure to perform a 3GPP W-CDMA reference sensitivity level test

on your BS. Perform the procedures in the subsections sequentially, in the order in which

they appear in this document.

Subsection 1. Equipment Setup and Preliminary BER Verification

Complete the following steps to connect the equipment and perform a BER verification test

on your BS.

Figure 2-16 Reference Sensitivity Level Equipment Setup

1. Connect the BS to the test system as shown in Figure 2-16.

a. Using the appropriate cables, adapters, and antennae, connect the output of the ESG

to the RF input of the BS.

b. If the BS has multiple input ports, terminate the unused ports.

c. Connect the system controller and the BER test platform to the BS.

2. Measure the Bit Error Ratio (BER) of the BS.

The controller or BER test platform measures the bit error ratio of the BS exposed to

the RF output power specified by TS 25.141.7.8 V3.4. This process verifies that the BER

of the BS is within specification before decreasing the amplitude of the RF output

power.

3. Record the first BER measurement result in the column titled, “Verification BER Value”

in Table 2-44.

4. 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.
