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