additional items may be installed in the transmit path. The additional
change in gain from these items could cause BLO verification failure
and, therefore, failure of the entire calibration. In these cases, either the
Verify BLO checkbox should be unchecked or the additional path losses
should be added into each applicable sector using the Util > Edit > TX
Coupler Loss... function.
Prerequisites
Before running this test, ensure that the following have been done:
S CSM–1, GLIs, MCCs, and BBX2s have correct code load and data
load.
S Primary CSM and MGLI are INS.
S All BBX2s are OOS_RAM.
S Test equipment and test cables are calibrated and connected for TX
BLO calibration.
S LMF is logged into the BTS in the GUI environment.
Connect the test equipment as shown in Figure 3-15 and Figure 3-16
and follow the procedure in Table 3-34 to perform the TX calibration
test.
Before installing any test equipment directly to any TX
OUT connector, first verify there are no CDMA BBX2
channels keyed. Failure to do so can result in serious
personal injury and/or equipment damage.
WARNING
Verify all BBX2 boards removed and repositioned have
been returned to their assigned shelves/slots. Any BBX2
boards moved since they were downloaded will have to be
downloaded again.
