Option 200 3GPP W-CDMA Base Station Performance Testing
• If the measured value is outside the limits, determine the cause of failure and repair
the BS. After repair, return to Step 1 of this subsection.
Subsection 2. Reference Sensitivity Level Measurement
Complete the following steps to make a reference sensitivity level measurement on your
BS.
1. Decrease the amplitude of the W-CDMA stimulus.
In accordance with the 3GPP W-CDMA RF specification, decrease the amplitude of the
RF output power to
−
121.00 dBm.
On the ESG,
Press
Amplitude >
−
121 > dBm.
2. Measure the BER of the BS at the decreased amplitude.
The controller or BER test platform measures the bit error ratio of the BS with a
W-CDMA stimulus amplitude of
−
121.00 dBm.
3. Record the BER result in the column titled, “Reference Sensitivity Level BER Value” in
Table 2-44.
4. Compare the recorded value of the BER result with the allowable values and record the
PASS/FAIL status for the BS.
Example Test Record
Use the following table to record the data from the RSL performance test.
