Introduction
Jan 2002 G-1
SCt4812ET BTS Optimization/ATP — CDMA LMF
Purpose
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
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.
IMPORTANT
*
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.
HP8921A Power Delta
Calibration
Use the HP8921A Spectrum Analyzer to measure power during
In–Service Calibration for 800 MHz systems. After the offset value has
been calculated, add it to the TX cable loss value.
Follow the procedure in Table G-1 to perform the HP8921A Power Delta
Calibration procedure.
This procedure requires two HP8921As.
NOTE
Table G-1: HP8921A Power Delta Calibration Procedure

* IMPORTANT
Perform this procedure after test equipment has been allowed to warm–up and stabilize for a minimum
of 60 minutes.

In–Service Calibration
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.
IMPORTANT
*
Prerequisites
SExpansion hardware has been added in the CBSC database, and the
CDF file has been generated.
SThe expansion devices have been inserted into the C–CCP cage and
are in the OOS_MANUAL state at the CBSC.
SThe site specific cdf (with the expansion hardware) and cal files have
been loaded onto the LMF.
SThe LMF has the same code and dds files as the CBSC to download.
Do not download code or data to any cards other than those
you are working on. Downloading code or data to other
cards will take the site OUT OF SERVICE.
The code file version numbers must match the version
numbers on the other cards in the frame. If the numbers do
not match, the site may go OUT OF SERVICE.
The BTS–#.cdf, CBSC–#.cdf, and CAL files for this BTS
must have come from the CBSC.
IMPORTANT
*
STest equipment has been configured per Figure G-9 or Figure G-10.
SAn RFDS (or at a minimum a directional coupler), whose loss is
already known, must be in line to perform the in–service calibration.
STest equipment has been calibrated after 1 hour warm up.
SA short RF cable and two BNC–N adapters are available to perform
Cable Calibration.

Cabling
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.
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.
