Power Calibration
This procedure is a guide to expanding your system with multiple
carriers while the system remains in service. This procedure also allows
you to perform on site maintenance (replace defective boards and
recalibrate) while the remainder of the site stays in service.
Motorola recommends that you perform this procedure during a
maintenance window.
This procedure cannot be performed on BTSs with 4-to-1 combiners.
The procedure can only be performed on one side of the BTS at one
time. That is, LPAs 1, 2 ,3, 7, 8, 9 (feed antennas 1, 2, 3) can be
calibrated while LPAs 6, 7, 8, 10, 11, 12 (feed antennas 4, 5, 6) remain
in service and vice versa.
Equipment Warm up
NOTE
Calibration of the communications test set (or equivalent test
equipment) must be performed at the site before calibrating the
overall test set. Calibrate the test equipment after it has been
allowed to warm-up and stabilize for a minimum of 60 minutes.
CAUTION
If any piece of test equipment (i.e., test cable, RF adapter) has
been replaced, re-calibration must be performed. Failure to do so
could introduce measurement errors, causing incorrect
measurements and degradation to system performance.
Power Delta Calibration Introduction
The In-service calibration procedure has several differences from a
normal calibration procedure. One of these is the use of a spectrum
analyzer instead of a power meter to measure power. Power meters are
broadband measurement devices and cannot be used to measure power
during In-service Calibration since other carriers are operating. A
spectrum analyzer can be used because it measures power at a given
frequency. However, measuring power using a spectrum analyzer is less
accurate than using a power meter. Therefore, you must compensate for
the difference (delta) between the power meter and the spectrum
analyzer.

NOTE
This feature does NOT have fault tolerance at this time. The
system has no safe-guards to stop you from doing something
that will take the BTS out of service. If possible, perform this
procedure during a maintenance window.
Follow the procedures in this section precisely, otherwise the
entire BTS will most likely go OUT OF SERVICE.
At the CBSC, only perform operations on expansion hardware
when it is in the OOS_MANUAL state.
The operator must be trained in the LMF operation prior to
performing this procedure.
Prerequisites
 Expansion hardware has been added in the CBSC database, and the
CDF file has been generated.
 The expansion devices have been inserted into the C-CCP cage and
are in the OOS_MANUAL state at the CBSC.
 The site specific cdf (with the expansion hardware) and cal files have
been loaded onto the LMF.
 The LMF has the same code and dds files as the CBSC to download.

This appendix provides the identification and location of the cables
connecting the components which make up the SC 4812ET RF cabinet.
The number of cables and components incorporated in the RF cabinet
will vary depending on the the manner in which the cabinet is equipped.
For example, a 3 sector, 2 carrier system will require less components
and less cables than a 6 sector 2 carrier system.
Refer to Table H-1 and Figure H-1 through Figure H-19 for the cable
you wish to research.
NOTE
In some cases cables with the same number are used to connect
two different signalling paths. These cables are designated A &
B and the point they connect to and from is also designated A &
B. Ensure the correct cable (A or B) is connected to the correct
designation (A or B) connector or plug.

DRDC/TRDC Cables and Cable Connections
The DRDC is a Duplexer, RX Filter, and Directional Coupler which
provides the RF interface at the rear of the cabinet. The connections are
the antenna connection (outside rear), transmit into the DRDC TX filter.
Receive out of DRDC (RX filter), and Directional coupler.
The TRDC is a TX filter/RX filter/Directional Coupler that is the same
as the DRDC except the TRDC has two antenna outputs (TX only and
RX only) The TRDC is not available in the 1.9 GHz band.
See Figure H-11, Figure H-12, Figure H-13, and Figure H-14 for the
cable diagram that fits the configuration of your BTS site.
