Acceptance Tests - Test Set-up
Required Test Equipment
The following test equipment is required:
LMF
Power meter (used with HP8921A/600 and Advantest R3465)
Communications system analyzer
Signal generator for FER testing (required for all communications
system analyzers for 1X FER)
WARNING
- Before installing any test equipment directly to any BTS
TX OUT connector, verify that there are no CDMA
channels keyed.
- At active sites, have the OMCR/CBSC place the carrier
assigned to the LPAs under test OOS. Failure to do so can
result in serious personal injury and/or equipment damage.
NOTE
The test equipment must be re-calibrated before using it to
perform the TX Acceptance Tests.
Acceptance Test Equipment Set Up
All ATP testing - Follow the steps in Table 4-3 to set up test equipment
for all tests.
Table 4-3: Set Up Test Equipment - TX Output Verify/Control Tests
Step Action
1 If it has not already been done, interface the LMF computer to the BTS (refer to Table 3-10 and
Figure 3-6).
2 If it has not already been done, refer to Table 3-11 to start a GUI LMF session and log into the BTS.
3
If it has not already been done, refer to Figure 3-16, Figure 3-17, Figure 3-18, Figure 3-19,
Figure 3-20, or Figure 3-21, as applicable, for the test equipment and antenna duplexing being used, to
connect test equipment for acceptance testing.
NOTE
LMF-based measurements factor in TX test cable loss between the RFMF and test equipment. If
additional attenuation, such as external TX combiners, is inserted in the path, it must be identified to
the LMF by including it in the TX test cable calibration. If this is not possible, include the attenuation
in the TX path by editing cable loss values (refer to Table 3-34). Failure to do this will result in test
inaccuracies and potential for erroneous ATP failures because the additional losses would not be
compensated for in the test measurements.
