Automated Acceptance Test Procedure
Introduction
The Acceptance Test Procedures (ATP) allow Cellular Field Engineers
(CFEs) to run automated acceptance tests on all BTS subsystem devices
equipped in the CDF using the LMF and the test equipment it supports.
The CFE can choose to save the results of ATP tests to a report file from
which ATP reports are generated for later printing. See the Generating an
ATP Report section in this chapter.
Because test equipment functions during acceptance testing are
controlled by the LMF through the GPIB, only the test equipment
models supported by the LMF can be used.
NOTE
– Before using the LMF, read the Release Notes “Caveats”
section in the LMF Help function on–line documentation
for any applicable information.
– The ATP test is to be performed on out-of-service sectors
only.
– DO NOT substitute test equipment with other models not
supported by the LMF.
Refer to Chapter 3 for detailed interconnection information needed for
calibrating equipment, cables, and other test equipment set components.
Reduced ATP
NOTE
Equipment has been factory–tested for FCC compliance. If
license–governing bodies require documentation supporting BTS
site compliance with regulations, a full ATP may be necessary.
Perform the Reduced ATP only if reports for the specific BTS
site are NOT required.
After downloading the proper operational software to the BTS, the CFE
must perform these procedures (minimum recommendation):
1. Verify the TX/RX paths by performing TX Calibration, TX Audit,
and FER tests.
2. Retrieve Calibration Data required for normal site operation.
Should failures occur while performing the specified tests, refer to the
Basic Troubleshooting section of this manual for help in determining the
failure point. Once the point of failure has been identified and corrected,
refer to the BTS Optimization and ATP Test Matrix (Table C-1) to
determine the applicable test that must be performed.
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.
