PRELIMINARY
4-3
In the unlikely event that the BTS passes these tests but has a forward
link problem during normal operation, the CFE should then perform the
additional TX tests for troubleshooting: TX spectral mask, TX rho, and
TX code domain.
NOTE
Refer to Chapter 3 for detailed information on test set
connections for calibrating equipment, cables and other test set
components, if required.
Customer requirements determine which ATP tests are to be performed
and the field engineer selects the appropriate ATP tests to run.
The tests can be run individually or as one of the following groups:
All TX: TX tests verify the performance of the BTS transmit line up.
These include the GLI3, MCC, BBX, and CIO cards, the LPAs and
passive components including splitters, combiners, bandpass filter,
and RF cables.
All RX: RX tests verify the performance of the BTS receiver line up.
These includes the MPC (for starter frames), EMPC (for expansion
frames), CIO, BBX, MCC, and GLI3 cards and the passive
components including RX filter (starter frame only), and RF cables.
All TX/RX: Executes all the TX and RX tests.
Full Optimization: Executes the TX calibration, download BLO, and
TX audit before running all of the TX and RX tests.
ATP Test Prerequisites
Before attempting to run any ATP tests, ensure the following:
BTS has been optimized and calibrated (see Chapter 3).
LMF is logged into the BTS.
CSMs, GLI3s, BBXs, MCCs and TSU (if the RFDS is installed)have
correct code load and data load
Primary CSM and GLI3 are INS_ACT
MCCs are INS_ACT.
BBXs are OOS-RAM.
BBXs are calibrated and BLOs are downloaded.
Test cables are calibrated.
Test equipment is selected.
Test equipment is connected for ATP tests.
Test equipment has been warmed up 60 minutes and calibrated.
GPIB is on.
WARNING
Before the FER is run, be sure that all LPAs are turned OFF
(circuit breakers pulled) or that all transmitter ports are properly
terminated.
All transmit ports must be properly terminated for all ATP tests.
Failure to observe these warnings may result in bodily injury or
equipment damage.
