1X SC 4812T Lite BTS Optimization/ATP Software Release R2.16.1.x

4-20

Overview – This test verifies the transmitted pilot channel element
digital waveform quality of each operator–selected BBX carrier keyed up
at a specific frequency specified in the current CDF. All tests are
performed using the external, calibrated test equipment controlled by the
same command. All measurements are made at the appropriate TX
antenna connector.

Equipment Operation During Testing – Pilot gain will be set to 262
for each antenna, and all TCH elements from the MCCs will be
forward–link disabled. The selected BBXs will be keyed up using both

bbxlvl

 and BLO to generate a CDMA carrier (with pilot channel

element only, Walsh code 0). RF output power is set at 40 dBm as
measured at the appropriate BTS TX antenna connector.

Test Measurements – The test equipment will measure and return the
pilot channel element digital waveform quality (rho) percentage,
verifying that the result meets the following specification:

Waveform quality (Rho) should be > 

0.912.

Redundant BBX Testing – The BBX will then de–key, and if selected,
the redundant BBX will be assigned to the current TX antenna path
under test. The test will then be repeated for the redundant BBX.
