SC4812ET BTS Optimization/ATP — CDMA LMF

Individual Acceptance Tests

The following individual ATP tests can be used to verify the results of

specific tests:

Spectral Purity TX Mask

This test verifies that the transmitted CDMA carrier waveform,

generated on each sector, meets the transmit spectral mask specification

with respect to the assigned CDF file values.

Waveform Quality (rho)

This test verifies that the transmitted Pilot channel element digital

waveform quality (rho) exceeds the minimum specified value in

ANSI–J_STD–019. “Rho” represents the correlation between actual and

perfect CDMA modulation spectrum. A rho value of 1.0000 represents

100% (or perfect correlation).

Pilot Time Offset

The Pilot Time Offset is the difference between the CDMA analyzer

measurement interval (based on the BTS system time reference) and the

incoming block of transmitted data from the BTS (Pilot only, Pilot

Gain = 262, PN Offset = 0).

Code Domain Power

This test verifies code domain power levels, which have been set for all

ODD numbered Walsh channels, using the OCNS command. This is

done by verifying that the ratio of PILOT divided by OCNS is equal to

10.2 + 2 dB, and, that the noise floor of all EVEN numbered “OFF”

Walsh channels measures

< –27 dB .

Frame Error Rate

The Frame Error Rate (FER) test verifies RX operation of the entire

CDMA Reverse Link using all equipped MCCs assigned to all

respective sector/antennas. The test verifies the BTS sensitivity on all

traffic channel elements currently configured on all equipped MCCs at

an RF input level of –119 dBm (or –116 dBm if using TMPC). Follow

the procedure in Table 4-1 to perform any ATP test.

The STOP button can be used to stop the testing process.
