1X SC 4812T BTS Optimization/ATP Software Release 2.16.1.x
FIELD TRIAL
3-74
CDF - performs the tests using pilot, synch, paging and six traffic
channels, however, the gain for the channel elements is specified in
the CDF file. Advanced users may use CDF to generate a standard
pattern. Instead of using the values specified by IS97, the settings for
the following CDF parameters are used:
- PilotGain
- PchGain
- SchGain
- NomGain1Way
Prerequisites
Before running this test, ensure that the following have been done:
CSM-1, GLIs, MCCs, and BBXs have correct code load and data
load.
Primary CSM and MGLI are INS.
All BBXs are OOS_RAM.
Test equipment and test cables are calibrated and connected for TX
BLO calibration.
LMF is logged into the BTS.
Connect the test equipment as shown in Figure 3-12 and follow the
procedure in Table 3-36 to perform the TX calibration test.
WARNING
Before installing any test equipment directly to any TX OUT
connector, first verify there are no CDMA BBX channels
keyed. Failure to do so can result in serious personal injury
and/or equipment damage.
NOTE
Verify all BBX boards removed and repositioned have been
returned to their assigned shelves/slots. Any BBX boards moved
since they were downloaded will have to be downloaded again.
Follow the procedure in Table 3-36 to perform the TX calibration test.
Table 3-36: BTS TX Path Calibration
Step Action
1 Select the BBX(s) to be calibrated.
NOTE
If STANDARD or CDF is selected for TEST PATTERN, then at least one MCC must be also
selected.
2 From the Tests menu, select TX>TX Calibration or All Cal/Audit.
3 Select the appropriate carrier(s) displayed in the Channels/Carrier pick list. (Press and hold the
<Shift> or <Ctrl> key to select multiple items.)
4 Type the appropriate channel number in the Carrier n Channels box.
5 Select Verify BLO (default) or Single-sided BLO.
NOTE
Single-sided BLO is only used when checking non-redundant transceivers.
