Background: FER Test
This test verifies the BTS FER on all traffic channel elements currently
configured on all equipped MCCs (full rate at 1% FER) at an RF input
level of -119 dBm [or -116 dBm if using Tower Top Amplifier
(TMPC)]. All tests are performed using the external calibrated test set as
the signal source controlled by the same command. All measurements
will be via the LMF.
The pilot gain is set to 262 for each TX antenna and all channel elements
from the MCCs are forward-link disabled. The BBX2 is keyed up using
only bbxlvl level offsets, to generate a CDMA carrier (with pilot channel
element only). BBX2 power output is set to -20 dBm as measured at the
TX OUT connector (on either the BTS or RFDS directional coupler).
The BBX2 must be keyed in order to enable the RX receive circuitry.
