PRELIMINARY

Individual Acceptance Tests

The following individual ATP tests can be used to evaluate specific

aspects of BTS operation against individual performance requirements.

All testing is performed using the CDMA LMF GUI environment.

TX Testing

TX tests verify any given transmit antenna path and output power

control. All tests are performed using the external calibrated test set. All

measurements are via the appropriate TX OUT connector.

TX tests verify TX operation of the entire CDMA Forward Link using

all BBX2s assigned to all respective sector/antennas. Each BBX2 is

keyed up to generate a CDMA carrier (using both bbx level and bay

level offsets) at the CDF file carrier output power level (as specified in

the site documentation).

RX Testing

RX testing verifies any given receive antenna path. All tests are

performed using the external calibrated test set to inject a CDMA RF

carrier with all zero longcode at the specified RX frequency via the

appropriate RX IN connector.

RX tests verify RX operation of the entire CDMA Reverse Link using

all equipped MCCs assigned to all respective sector/antennas.

Individual Tests

Spectral Purity TX Mask

This test verifies that the transmitted CDMA carrier waveform generated

on each sector meets the transmit spectral mask specification (as defined

in IS–97) 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 IS–97.

Rho represents the correlation between the actual and perfect CDMA

modulation spectrums. 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, Walsh

code 0).

Code Domain Power/Noise Floor

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

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