Test Pattern Drop–down Pick List
The Tests > TX > TX Calibration... menu window has a Test Pattern
pull–down menu. This menu has the following choices:
S Standard – performs calibration or audit using pilot, paging, synch,
and six traffic channels with IS–97–specified gain. This pattern setting
should be used for all non–in–service calibrations and audits. Using
this pattern setting requires the selection of both a BBX and at least
one MCC.
S Pilot (default) – performs calibration using only the pilot channel.
This pattern setting should be used for in–service calibrations, and
requires selection of only a BBX.
S CDFPilot – This pattern setting is for advanced users. It performs
calibration or audit using the CDF value for pilot gain and IS–97 gain
values for all the other channels included in the Standard pattern
setting (paging, synch, and six traffic). Using this pattern setting
requires the selection of both a BBX and at least one MCC.
S CDF – This pattern setting is for advanced users who need to use
CDF gain settings for all channels included in the Standard pattern
setting (pilot, paging, synch, and six traffic). Using this pattern setting
requires the selection of both a BBX and at least one MCC.
Test Pattern Channels and Gain Settings – The CDMA channels and
their respective digital gain settings used for each test pattern are listed
in Table 3-34.
