Bay Level Offset Calibration – continued
3-120 1X SC 4812T Lite BTS Optimization/ATP FEB 2005
PRELIMINARY
Primary BBX Cards normally will have BLOs in the lower half of the
range. Using the example range, this would be from 40 to 45 dB.
Checking the Single–Sided BLO Check Box should only be done when
calibrating Primary BBX Cards because it will reduce the acceptable
BLO Value variations to the lower half of the range. Because this is a
much more stringent tolerance, Calibrations run with Single–Sided
BLO are more likely to fail and should only be attempted by an
experienced CFE.
Never select Single–Sided BLO when calibrating a
Redundant BBX.

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 one
BBX and at least one MCC.
IMPORTANT
*
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 one BBX.
IMPORTANT
*
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 one
BBX and at least one MCC.
IMPORTANT
*
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 one
BBX and at least one MCC.
