1X UBS Macro B T S Optimization/A TP Ba y Lev el Offset Calibr ation

Single–sided BLO Checkbox

Another option that appears in the pull–down menu is Single–sided BLO . Normally valid

BLO values are some value plus–or–minus some offset. Single–sided BLO spec is >–3.5 dB.

Double–sided BLO spec is –1.5 +/– 2.0 dB. T o get the more stringent conditions, the operator

checks Single–sided BLO when calibrating non -redundant transceivers. Single–sided BLO

carries the likelihood of more failures. This option should only be used by experienced CFEs.

The T ests > TX > TX Calibration... menu window has a T est P attern pull–down menu. This

menu has the following choices.

• Pilot (default) – performs tests using a pilot signal only . This pattern should be used when

running in–service tests. It requires the DMIs to do the test.

• Standard – performs the tests using pilot, synch, paging and six trafﬁc channels.

• CDFPilot – performs the tests using the pilot signal, however , the gain is speciﬁed in the

NEC ﬁle. Advanced users may use CDFPilot to generate a Pilot pattern using the value

speciﬁed by the Pilot Gain parameter in the NEC ﬁle instead of a predetermined value.

• CDF – performs the tests using pilot, synch, paging and six trafﬁc channels, however , the

gain for the channel elements is speciﬁed in the NEC ﬁle. Advanced users may use NEC to

generate a standard pattern. Instead of using the values speciﬁed by IS–97, the settings

for the following NEC parameters are used:
