General Test Procedural
Changes for SC 4812T-MC
The GENERAL information herein summarizes procedural
changes introduced with the SC 4812T–MC BTS. Detailed
procedures are provided in the Optimization and ATP
sections.
NOTE
1. During the execution of any TX tests or calibration
procedures, ALL Power Amplifiers (PA) must be in
service (INS).
2. When logging into a BTS with a system release earlier
than 2.16.4.x, be sure to set BTS type to MultiCarrier
in the dialog box which will appear when logging into
the BTS.
NOTE
Transmit (TX) Bay Level Offset (BLO) Specifications –
SC4812T–MC TX BLO specifications for different BTS sector
configurations are as follows:
S 800 MHz Three–sector BTS:
Single–sided BLO: >35dB
Double–sided BLO: 40dB +/– 5dB
S 800 MHz Six–sector BTS
Single–sided BLO: >38dB
Double–sided BLO: 43dB +/– 5dB
S 1.9 GHz Three–sector BTS:
Single–sided BLO: >30dB
Double–sided BLO: 35dB +/– 5dB
S 1.9 GHz Six–sector BTS
Single–sided BLO: >33dB
Double–sided BLO: 38dB +/– 5dB
Verifying Pilot Power Setting
with a Wide Band RF Power
Meter
The SC4812T–MC requires all equipped PAs be enabled during TX test.
With a “tuned” RF power meter, such as the Agilent VSA E4406A, all
sectors–carriers can be enabled simultaneously and each sector–carrier
power level setting can be measured. The following work–around
procedures are suggested when using a wide band RF power meter and
the BTS is under OMC–R control.
