![RX Frame Error Rate (FER) Acceptance TestDRAFTSCt4812T CDMA BTS Optimization/ATP Mar 20014-12FER TestThis test verifies the BTS FER on all traffic channel elements currentlyconfigured on all equipped MCCs (full rate at 1% FER) at an RF inputlevel of –119 dBm [or –116 dBm if using Tower TopAmplifier (TMPC)]. All tests are performed using the external calibratedtest set as the signal source controlled by the same command. Allmeasurements are via the LMF.The Pilot Gain is set to 262 for each TX antenna, and all channelelements from the MCCs are forward-link disabled. The BBX is keyedup, using only bbxlvl level offsets, to generate a CDMA carrier (withpilot channel element only). BBX power output is set to –20 dBm asmeasured at the TX OUT connector (on either the BTS or RFDSdirectional coupler). The BBX must be keyed to enable the RX receivecircuitry.The LMF prompts the MCC/CE under test to measure all zero longcodeand provide the FER report on the selected active MCC on the reverselink for both the main and diversity RX antenna paths, verifying thatresults meet the following specification:SFER returned less than 1% and total frames measured is 1500All MCC/CEs selected are tested on the specified RX antenna path. TheBBX then de-keys and, if selected, the MCC is re-configured to assignthe applicable redundant BBX to the current RX antenna paths undertest. The test is then repeated.4](https://usermanual.wiki/Nokia-Solutions-and-Networks/T5BL1.IHET5BL1-User-Manual-Part-3-of-3/User-Guide-167768-Page-12.png)

Thus, only components having losses ≤30 dBshould be measured using this method. For further accuracy, always re-zero the power meterbefore connecting the power sensor to the component being calibrated. After connecting thepower sensor to the component, record the calibrated loss immediately.18 Disconnect all components in the test setup and calibrate each one separately by connecting eachcomponent, one-at-a-time, between the RF OUT ONLY PORT and the power sensor (see Figure F-1,Setups A, B, or C). Record the calibrated loss value displayed on the power meter.SExample: (A) Test Cable(s) = –1.4 dB(B) 20 dB Attenuator = –20.1 dB(B) Directional Coupler = –29.8 dB. . . continued on next pageF](https://usermanual.wiki/Nokia-Solutions-and-Networks/T5BL1.IHET5BL1-User-Manual-Part-3-of-3/User-Guide-167768-Page-118.png)
