up, using only bbxlvl level offsets, to generate a CDMA carrier (with

pilot channel element only). BBX power output is set to –20 dBm as

measured at the TX OUT connector (on either the BTS or RFDS

directional coupler). The BBX must be keyed to enable the RX receive

circuitry.

The LMF prompts the MCC/CE under test to measure all zero longcode

and provide the FER report on the selected active MCC on the reverse

link for both the main and diversity RX antenna paths, verifying that

results meet the following specification:

S FER returned less than 1% and total frames measured is 1500

All MCC/CEs selected are tested on the specified RX antenna path. The

BBX then de-keys and, if selected, the MCC is re-configured to assign

the applicable redundant BBX to the current RX antenna paths under

test. The test is then repeated.

See Table 4-1 to perform this test.
