Automated Acceptance Test Procedures – TX & RX – continued
4-2 1X SC4812T–MC BTS Optimization/ATP 5/21/04
DRAFT
Reduced ATP
Equipment has been factory–tested for FCC compliance. If
license–governing bodies require documentation
supporting 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.
NOTE
After downloading the proper operational software to the BTS, the CFE
must perform these procedures (minimal recommendation):
S Verify the TX/RX paths by performing TX Calibration, TX Audit and
FER tests.
S 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-3, page
C-4) section 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.
Required Test Equipment
The following test equipment is required:
S LMF
S Power meter (used with HP8921A/600 and Advantest R3465)
S Communications system analyzer
S Signal generator for FER testing (required for all communications
system analyzers for 1X FER)
S Before installing any test equipment directly to any
BTS TX OUT connector, verify that there are no
CDMA channels keyed.
S At active sites, have the OMCR/CBSC place the carrier
assigned to the PAs under test OOS. Failure to do so
can result in serious personal injury and/or equipment
damage.
WARNING
The test equipment must be re–calibrated before using it to
perform the TX Acceptance Tests.
