Automated Acceptance Test Procedures – All–inclusive TX & RX
Introduction
The Automated Acceptance Test Procedure (ATP) allows Cellular Field
Engineers (CFEs) to run automated acceptance tests on all equipped BTS
subsystem devices using the Local Maintenance Facility (LMF) and
supported test equipment per the current Cell Site Data File (CDF)
assignment.
The results of these tests (at the option of the operator) are written to a
file that can be printed. All tests are controlled from the LMF platform
using the GPIB interface, therefore, only recommended test equipment
supported by the LMF can be used.
This chapter describes the tests run from the GUI environment, which is
the recommended method. The GUI provides the advantages of
simplifying the LMF user interface, reducing the potential for miskeying
commmands and associated parameters, and speeding up the execution
of complex operations involving multiple command strings. If you feel
the command line interface (CLI) will provide additional insight into the
progress of ATPs and problems that could possibly be encountered, refer
to LMF CLI Commands, R15.X (68P09251A59).
IMPORTANT
Before performing any tests, use an editor to view the
“CAVEATS” section of the “readme.txt” file in the c:\wlmf
folder for any applicable information.
The ATP test is to be performed on out-of-service (OOS)
sectors only.
DO NOT substitute test equipment not supported by the
LMF.
NOTE
Refer to Chapter 3 for detailed information on test set
connections for calibrating equipment, cables and other test
set components, if required.
Customer requirements determine which ATP tests to are to be
performed, and the craftsperson selects the appropriate ATP tests to run.
The tests can be run individually or as one of the following groups:

 All TX: TX tests verify the performance of the BTS transmit line up.
These include the GLI, MCC, BBX, and CIO cards, the LPAs and
passive components including splitters, combiners, bandpass filters,
and RF cables.

 All RX: RX tests verify the performance of the BTS receiver line up.
These include the MPC (for starter frames), EMPC (for expansion
frames), CIO, BBX, MCC, and GLI cards and the passive components
including RX filters (starter frame only), and RF cables.

 All TX/RX: Executes all the TX and RX tests.

 Full Optimization: Executes the TX calibration, downloads the BLO,
and executes the TX audit before running all of the TX and RX tests.
ATP Test Prerequisites
Before attempting to run any ATP tests, ensure the following have been
completed:

 BTS has been optimized and calibrated (see Chapter 3).

 LMF is logged into the BTS.

 CSMs, GLIs, BBXs, MCCs, and TSU (if the RFDS is installed) have
correct code load and data load.

 Primary CSM, GLI, and MCCs are INS_ACT.

 BBXs are calibrated and BLOs are downloaded.

 BBXs are OOS_RAM.

 Test cables are calibrated.

 Test equipment is connected for ATP tests (see Figure 3-13 through
Figure 3-16 starting on page 3-50).

 Test equipment has been warmed up 60 minutes and calibrated.

 GPIB is on.
WARNING
Before performing the FER, be sure that all LPAs are
turned OFF (circuit breakers pulled) or that all transmitter
ports are properly terminated.
All transmit ports must be properly terminated for all ATP
tests.
Failure to observe these warnings may result in bodily
injury or equipment damage.
TX OUT Connection
IMPORTANT
4-2
Many of the acceptance test procedures require taking
measurements at the TX OUT (BTS/RFDS) connector. At
sites without RFDS installed, all measurements will be via
the BTS TX OUT connector. At sites with RFDS installed,
all measurements will be via the RFDS directional coupler
TX OUT connector.

TX Output Acceptance Tests: Introduction
Individual Acceptance Tests
The following individual tests can be used to verify the results of
specific tests.
Spectral Purity TX Mask (Primary & Redundant BBX)
This test verifies that the transmitted CDMA carrier waveform generated
on each sector meets the transmit spectral mask specification with
respect to the assigned CDF file values.
Waveform Quality (rho)
This test verifies that the transmitted Pilot channel element digital
waveform quality (rho) exceeds the minimum specified value in
ANSI–J_STD–019. “Rho” represents the correlation between actual and
perfect CDMA modulation spectrum. A rho value of 1.0000 represents
100% (or perfect correlation).
Pilot Time Offset
The Pilot Time Offset is the difference between the CDMA analyzer
measurement interval (based on the BTS system time reference) and the
incoming block of transmitted data from the BTS (Pilot only, Pilot
Gain = 262, PN Offset = 0).
Code Domain Power (Primary & Redundant BBX)
This test verifies the code domain power levels, which have been set for
all ODD numbered Walsh channels, using the OCNS command. This is
done by verifying that the ratio of PILOT divided by OCNS is equal to
10.2 $ 2 dB, and, that the noise floor of all EVEN numbered “OFF”
Walsh channels measures v –27 dB (with respect to total CDMA
channel power).
Frame Error Rate
The Frame Error Rate (FER) test verifies RX operation of the entire
CDMA Reverse Link using all equipped MCCs assigned to all
respective sector/antennas. This test verifies the BTS sensitivity on all
traffic channel elements currently configured on all equipped MCCs at
an RF input level of –119 dBm (or –116 dBm if using TMPC).

TX Spectral Purity Transmit Mask Acceptance Test
Tx Mask Test
This test verifies the spectral purity of each BBX carrier keyed up at a
specific frequency, per the current CDF file assignment. All tests are
performed using the external calibrated test set, controlled by the same
command. All measurements are via the appropriate TX OUT
(BTS/RFDS) connector.
The Pilot Gain is set to 541 for each antenna, and all channel elements
from the MCCs are forward-link disabled. The BBX is keyed up, using
both bbxlvl and bay level offsets, to generate a CDMA carrier (with pilot
channel element only). BBX power output is set to obtain +40 dBm as
measured at the TX OUT connector (on either the BTS or RFDS
directional coupler).
NOTE
TX output power is set to +40 dBm by setting BTS power
level to +33.5 dBm to compensate for 6.5 dB increase from
pilot gain set to 541.
The calibrated communications test set measures and returns the
attenuation level of all spurious and IM products in a 30 kHz resolution
bandwidth. With respect to the mean power of the CDMA channel
measured in a 1.23 MHz bandwidth in dB, verify that results meet
system tolerances at the following test points:

 1.7/1.9 GHz:
– at least –45 dB @ + 900 kHz from center frequency
– at least –45 dB @ – 900 kHz from center frequency

 800 MHz:
–

–
–
at least –45 dB @ + 750 kHz from center frequency
at least –45 dB @ – 750 kHz from center frequency
at least –60 dB @ – 1980 kHz from center frequency
at least –60 dB @ – 1980 kHz from center frequency
The BBX then de-keys, and, if selected, the MCC is re-configured to
assign the applicable redundant BBX to the current TX antenna path
under test. The test is then repeated.

TX Waveform Quality (rho) Acceptance Test
Rho Test
This test verifies the transmitted Pilot channel element digital waveform
quality of each BBX carrier keyed up at a specific frequency per the
current CDF file assignment. All tests are performed using the external
calibrated test set controlled by the same command. All measurements
are via the appropriate TX OUT (BTS/RFDS) connector.
The Pilot Gain is set to 262 for each antenna, and all channel elements
from the MCCs are forward link disabled. The BBX is keyed up using
both bbxlvl and bay level offsets, to generate a CDMA carrier (with pilot
channel element only, Walsh code 0). BBX power output is set to
40 dBm as measured at the TX OUT connector (on either the BTS or
RFDS directional coupler).
The calibrated communications test set measures and returns the Pilot
channel element digital waveform quality (rho) in dB, verifying that the
result meets system tolerances:

 Waveform quality (rho) should be > 0.912 (–0.4 dB).
The BBX then de-keys and, if selected, the MCC is re-configured to
assign the applicable redundant BBX to the current TX antenna path
under test. The test is then be repeated.

Pilot Offset Acceptance Test
This test verifies the transmitted Pilot channel element Pilot Time Offset
of each BBX carrier keyed up at a specific frequency per the current
CDF file assignment. All tests are performed using the external
calibrated test set controlled by the same command. All measurements
are via the appropriate TX OUT (BTS/RFDS) connector.
The Pilot Gain is set to 262 for each antenna, and all TCH elements from
the MCCs are forward link disabled. The BBX is keyed up, using both
bbxlvl and bay level offsets, to generate a CDMA carrier (with pilot
channel element only, Walsh code 0). BBX power output is set to
40 dBm as measured at the TX OUT connector (on either the BTS or
RFDS directional coupler).
The calibrated communications test set measures and returns the Pilot
Time Offset in µs, verifying results meet system tolerances:

 Pilot Time Offset should be within < 3 µs of the target PT
Offset (0 µs).
The BBX then de-keys, and if selected, the MCC is re-configured to
assign the applicable redundant BBX to the current TX antenna path
under test. The test is then repeated.

TX Code Domain Power/Noise Floor Acceptance Test
Code Domain Power Test
This test verifies the Code Domain Power/Noise of each BBX carrier
keyed up at a specific frequency per the current CDF file assignment.
All tests are performed using the external calibrated test set controlled by
the same command. All measurements are via the appropriate TX OUT
(BTS/RFDS) connector.
For each sector/antenna under test, the Pilot Gain is set to 262. All MCC
channel elements under test are configured to generate Orthogonal
Channel Noise Source (OCNS) on different odd Walsh codes and to be
assigned a full–rate gain of 81. The maximum number of MCC/CEs to
be tested an any one time is 32 (32 odd Walsh codes). If more than 32
CEs exist, then multiple sets of measurements are made; so all channel
elements are verified on all sectors.
BBX power output is set to 40 dBm as measured at the TX OUT
connector (on either the BTS or RFDS directional coupler).
You verify the code domain power levels, which have been set for all
ODD numbered Walsh channels, using the OCNS command. This is
done by verifying that Pilot Power (dBm) minus OCNS Power (dBm) is
equal to 10.2 + 2 dB and that the noise floor of all “OFF” Walsh channels
measures < –27 dB (with respect to total CDMA channel power).
The BBX then de-keys and, if selected, the MCC is re-configured to
assign the applicable redundant BBX to the current TX antenna path
under test. The test is then repeated. Upon completion of the test, OCNS
is disabled on the specified MCC/CE.

RX Frame Error Rate (FER) Acceptance Test
FER Test
This test verifies the BTS FER on all traffic channel elements currently
configured on all equipped MCCs (full rate at 1% FER) at an RF input
level of –119 dBm [or –116 dBm if using Tower Top
Amplifier (TMPC)]. All tests are performed using the external calibrated
test set as the signal source controlled by the same command. All
measurements are via the LMF.
The Pilot Gain is set to 262 for each TX antenna, and all channel
elements from the MCCs are forward-link disabled. The BBX is keyed
up, using only bbxlvl level offsets, to generate a CDMA carrier (with
pilot channel element only). BBX power output is set to –20 dBm as
measured at the TX OUT connector (on either the BTS or RFDS
directional coupler). The BBX must be keyed to enable the RX receive
circuitry.
The LMF prompts the MCC/CE under test to measure all zero longcode
and provide the FER report on the selected active MCC on the reverse
link for both the main and diversity RX antenna paths, verifying that
results meet the following specification:

 FER returned less than 1% and total frames measured is 1500
All MCC/CEs selected are tested on the specified RX antenna path. The
BBX then de-keys and, if selected, the MCC is re-configured to assign
the applicable redundant BBX to the current RX antenna paths under
test. The test is then repeated.

Troubleshooting: CSM Checklist
Problem Description
Many of the Clock Synchronization Manager (CSM) board failures may
be resolved in the field before sending the boards to the factory for
repair. This section describes known CSM problems identified in field
returns, some of which are field-repairable. Check these problems before
returning suspect CSM boards.
Intermittent 19.6608 MHz
Reference Clock/GPS
Receiver Operation
If having any problems with CSM board kit numbers, SGLN1145 or
SGLN4132, check the suffix with the kit number. If the kit has version
“AB”, then replace with version “BC” or higher, and return model “AB”
to the repair center.
No GPS Reference Source
Check the CSM boards for proper hardware configuration. CSM kit
SGLN1145, in Slot l, has an on-board GPS receiver; while kit
SGLN4132, in Slot 2, does not have a GPS receiver. Any incorrectly
configured board must be returned to the repair center. Do not attempt to
change hardware configuration in the field. Also, verify the GPS
antenna is not damaged and is installed per recommended guidelines.
Checksum Failure
The CSM could have corrupted data in its firmware resulting in a
non-executable code. The problem is usually caused by either electrical
disturbance or interruption of data during a download. Attempt another
download with no interruptions in the data transfer. Return the CSM

C–CCP Backplane Troubleshooting
Introduction
The C–CCP backplane is a multi–layer board that interconnects all the
C–CCP modules. The complexity of this board lends itself to possible
improper diagnoses when problems occur.
Connector Functionality
The following connector overview describes the major types of
backplane connectors along with the functionality of each. This
information allows the CFE to:

 Determine which connector(s) is associated with a specific problem
type.

 Isolate problems to a specific cable or connector.
Primary “A” and Redundant “B” Inter Shelf Bus Connectors
The 40 pin Inter Shelf Bus (ISB) connectors provide an interface bus
from the master GLI2 to all other GLI2s in the modem frame. Their
basic function is to provide clock synchronization from the master GLI2
to all other GLI2s in the frame.
The ISB also provides the following functions:

 Span line grooming when a single span is used for multiple cages.

 MMI connection to/from the master GLI2 to cell site modem.

 Interface between GLI2s and the AMR (for reporting BTS alarms).
Span Line Connector
The span line input is an 8–pin RJ–45 connector that provides a primary
and secondary (if used) span line interface to each GLI2 in the C–CCP
shelf. The span line is used for MM/EMX switch control of the Master
GLI2 and also all the BBX traffic.
Primary “A” and Redundant “B” Reference Distribution
Module Input/Output
The Reference Distribution Module (RDM) connectors route the 3 MHz
reference signals from the CSMs to the GLI2s and all BBXs in the
backplane. The signals are used to phase lock loop all clock circuits on
the GLI2s and BBX boards to produce precise clock and signal
frequencies.
Power Input (Return A, B, and C connectors)
Provides a +27 volt or –48 volt input for use by the power supply
modules.

C–CCP Backplane Troubleshooting – continued
Power Supply Module Interface
Each power supply module has a series of three different connectors to
provide the needed inputs/outputs to the C–CCP backplane. These
include a VCC/Ground input connector, a Harting style multiple pin
interface, and a +15 V/Analog Ground output connector. The C–CCP
Power Modules convert +27 or –48 Volts to a regulated +15, +6.5, and
+5.0 Volts to be used by the C–CCP shelf cards. In the –48 V BTS, the
LPA power modules convert –48 Volts to a regulated +27 Volts.
GLI2 Connector
This connector consists of a Harting 4SU digital connector and a
6–conductor coaxial connector for RDM distribution. The connectors
provide inputs/outputs for the GLI2s in the C–CCP backplane.
GLI2 Ethernet “A” and “B” Connections
These BNC connectors are located on the C–CCP backplane and routed
to the GLI2 board. This interface provides all the control and data
communications between the master GLI2 and the other GLI2, between
gateways, and for the LMF on the LAN.
BBX Connector
Each BBX connector consists of a Harting 2SU/1SU digital connector
and two 6–conductor coaxial connectors. These connectors provide DC,
digital, and RF inputs/outputs for the BBXs in the C–CCP backplane.
CIO Connectors

 RX RF antenna path signal inputs are routed through RX Tri–Filters
(on the I/O plate), and via coaxial cables to the two MPC modules –
the six “A” (main) signals go to one MPC; the six “B” (diversity) to
the other. The MPC outputs the low–noise–amplified signals via the
C–CCP backplane to the CIO where the signals are split and sent to
the appropriate BBX.

 A digital bus then routes the baseband signal through the BBX, to the
backplane, then on to the MCC slots.

 Digital TX antenna path signals originate at the MCCs. Each output
is routed from the MCC slot via the backplane appropriate BBX.

 TX RF path signal originates from the BBX, through the backplane to
the CIO, through the CIO, and via multi-conductor coaxial cabling to
the LPAs in the LPA shelf.

DC Power Problems
Perform the procedure in Table 6-22 to troubleshoot a DC input voltage
to power supply module failure.
WARNING
Potentially lethal voltage and current levels are routed to
the BTS equipment. This test must be carried out with a
second person present, acting in a safety role. Remove all
rings, jewelry, and wrist watches prior to beginning this
test.
No DC Input Voltage to Power Supply Module
Table 6-22: No DC Input Voltage to Power Supply Module
Step
Action
Verify DC power is applied to the BTS frame.
Verify there are no breakers tripped.
* IMPORTANT
If a breaker has tripped, remove all modules from the applicable shelf supplied by the breaker and
attempt to reset it.
– If the breaker trips again, there is probably a cable or breaker problem within the frame.
– If the breaker does not trip, there is probably a defective module or sub–assembly within the shelf.
Verify that the C–CCP shelf breaker on the BTS frame breaker panel is functional.
Use a voltmeter to determine if the input voltage is being routed to the C–CCP backplane by
measuring the DC voltage level on the PWR_IN cable.
– If the voltage is not present, there is probably a cable or breaker problem within the frame.
– If the voltage is present at the connector, reconnect and measure the level at the “VCC” power
feed clip on the distribution backplane.
– If the voltage is correct at the power clip, inspect the clip for damage.
If everything appears to be correct, visually inspect the power supply module connectors.
Replace the power supply module with a known good module.
If steps 1 through 5 fail to indicate a problem, a C–CCP backplane failure (possibly an open trace) has
occurred.

PN Offset Programming Information
PN Offset Background
All channel elements transmitted from a BTS in a particular 1.25 MHz
CDMA channel are orthonogonally spread by 1 of 64 possible Walsh
code functions; additionally, they are also spread by a quadrature pair of
PN sequences unique to each sector.
Overall, the mobile uses this to differentiate multiple signals transmitted
from the same BTS (and surrounding BTS) sectors, and to synchronize
to the next strongest sector.
The PN offset per sector is stored on the BBXs, where the corresponding
I & Q registers reside.
The PN offset values are determined on a per BTS/per sector(antenna)
basis as determined by the appropriate cdf file content. A breakdown of
this information is found in Table B-1.
PN Offset Usage
Only the 14–chip delay is currently in use. It is important to determine
the RF chip delay to be able to test the BTS functionality. This can be
done by ascertaining if the CDF file FineTxAdj value was set to “on”
when the MCC was downloaded with “image data”. The FineTxAdj
value is used to compensate for the processing delay (approximately
20 mS) in the BTS using any type of mobile meeting IS–97
specifications.
If the FineTxAdj value in the cdf file is 213 (D5 HEX), FineTxAdj has
been set for the 14 chip table.
IMPORTANT
Mar 2001
CDF file I and Q values can be represented in DECIMAL
or HEX. If using HEX, add 0x before the HEX value. If
necessary, convert HEX values in Table B-1 to decimal
before comparing them to cdf file I & Q value assignments.

between BTS frames.

Detailed Optimization/ATP
Test Matrix
Table C-3 outlines in more detail the tests that would need to be
performed if one of the BTS components were to fail and be replaced. It
is also assumed that all modules are placed OOS–ROM via the LMF
until full redundancy of all applicable modules is implemented.
The following guidelines should also be noted when using this table.
IMPORTANT
Not every procedure required to bring the site back on line
is indicated in Table C-3. It is meant to be used as a
guideline ONLY. The table assumes that the user is familiar
enough with the BTS Optimization/ATP procedure to
understand which test equipment set ups, calibrations, and
BTS site preparation will be required before performing the
Table # procedures referenced.
Various passive BTS components (such as the TX and RX directional
couplers, Preselector IO, CIO; etc.) only call for a TX or RX calibration
audit to be performed in lieu of a full path calibration. If the RX or TX
path calibration audit fails, the entire RF path calibration will need to be
repeated. If the RF path calibration fails, further troubleshooting is
warranted.
Whenever any C–CCP BACKPLANE is replaced, it is assumed that
only power to the C–CCP shelf being replaced is turned off via the
breaker supplying that shelf.
Whenever any DISTRIBUTION BACKPLANE is replaced it is assumed
that the power to the entire RFM frame is removed and the Preselector
I/O is replaced. The modem frame should be brought up as if it were a
new installation.

NOTE
If any significant change in signal level results from any
component being replaced in the RX or TX signal flow
paths, it would be identified by re–running the RX and TX
calibration audit command.
When the CIO is replaced, the C–CCP shelf remains powered up. The
BBX boards may need to be removed, then re–installed into their
original slots, and re–downloaded (code and BLO data). RX and TX
calibration audits should then be performed.

BBX Gain Set Point vs. BTS Output Considerations
Usage & Background
Table D-1 outlines the relationship between the total of all code domain
channel element gain settings (digital root sum of the squares) and the
BBX Gain Set Point between 33.0 dBm and 44.0 dBm. The resultant RF
output (as measured at the top of the BTS in dBm) is shown in the table.
The table assumes that the BBX Bay Level Offset (BLO) values have
been calculated.
As an illustration, consider a BBX keyed up to produce a CDMA carrier
with only the Pilot channel (no MCCs forward link enabled). Pilot gain
is set to 262. In this case, the BBX Gain Set Point is shown to correlate
exactly to the actual RF output anywhere in the 33 to 44 dBm output
range. (This is the level used to calibrate the BTS).

Introduction
Programming of each of the BTS BBX synthesizers is performed by the
BTS GLIs via the CHI bus. This programming data determines the
transmit and receive transceiver operating frequencies (channels) for
each BBX.
1900 MHz PCS Channels
Figure E-1 shows the valid channels for the North American PCS
1900 MHz frequency spectrum. There are 10 CDMA wireline or
non–wireline band channels used in a CDMA system (unique per
customer operating system).

Calculating 1900 MHz Center
Frequencies
Table E-1 shows selected 1900 MHz CDMA candidate operating
channels, listed in both decimal and hexadecimal, and the corresponding
transmit, and receive frequencies. Center frequencies (in MHz) for
channels not shown in the table may be calculated as follows:

 TX = 1930 + 0.05 * Channel#
Example: Channel 262
TX = 1930 + 0.05*262 = 1943.10 MHz

 RX = TX – 80
Example: Channel 262
RX = 1943.10 – 80 = 1863.10 MHz
Actual frequencies used depend on customer CDMA system frequency
plan.
Each CDMA channel requires a 1.77 MHz frequency segment. The
actual CDMA carrier is 1.23 MHz wide, with a 0.27 MHz guard band on
both sides of the carrier.
Minimum frequency separation required between any CDMA carrier and
the nearest NAMPS/AMPS carrier is 900 kHz (center-to-center).

Calculating 800 MHz Center
Frequencies
Table E-2 shows selected 800 MHz CDMA candidate operating
channels, listed in both decimal and hexadecimal, and the corresponding
transmit, and receive frequencies. Center frequencies (in MHz) for
channels not shown in the table may be calculated as follows:

 Channels 1–777
TX = 870 + 0.03 * Channel#
Example: Channel 262
TX = 870 + 0.03*262 = 877.86 MHz

 Channels 1013–1023
TX = 870 + 0.03 * (Channel# – 1023)
Example: Channel 1015
TX = 870 +0.03 *(1015 – 1023) = 869.76 MHz

 RX = TX – 45 MHz
Example: Channel 262
RX = 877.86 –45 = 832.86 MHz

Test Equipment Setup
Purpose
This section covers other test equipment and peripherals not covered in
Chapter 3. Procedures for the manual testing are covered here, along
with procedures to calibrate the TX and RX cables using the signal
generator and spectrum analyzer.
Equipment Warm up
IMPORTANT
Warm-up BTS equipment for a minimum of 60 minutes
prior to performing the BTS optimization procedure. This
assures BTS site stability and contributes to optimization
accuracy. (Time spent running initial power-up, hardware/
firmware audit, and BTS download counts as warm-up
time.)
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,
resulting in incorrect measurements and degradation to
system performance.
IMPORTANT
Mar 2001
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.

Transmit & Receive Antenna VSWR
Purpose
The following procedures will verify that the Voltage Standing Wave
Ratio (VSWR) of all antennas and associated feed lines fall within
acceptable limits. The tests will be performed on all antennas in a
sequential manner (i.e., ANT 1, then ANT 2) until all antennas/feedlines
have been verified.
These procedures should be performed periodically by measuring each
respective antenna’s VSWR (reflected power) to verify that the antenna
system is within acceptable limits. This will ensure continued peak
system performance.
The antenna VSWR will be calculated at the CDMA carrier frequency
assigned to each antenna. Record and verify that they meet the test
specification of less than or equal to 1.5:1.
IMPORTANT
It is recommended that the installer be familiar with the
following procedure in its entirety before beginning the
actual procedure. Ensure that the entire site is currently not
in service.
NOTE
This test is used to test RX antennas by substituting RX
frequencies for TX frequencies.
Study the site engineering documents and perform the following tests
only after first verifying that the RF cabling configuration required to
interconnect the BTS frames and antennas meet requirements called out
in the BTS Installation Manual.
Test equipment
The following pieces of test equipment will be required to perform this
test:

 LMF

 Directional coupler

 Communications test set
WARNING
Prior to performing antenna tests, insure that no CDMA
BBX channels are keyed. Failure to do so could result in
personal injury or serious equipment damage.

Introduction
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
IMPORTANT
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
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 I-1 to perform the HP8921A Power Delta
Calibration procedure.
NOTE

In–Service Calibration
IMPORTANT
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.
IMPORTANT
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.

 Test equipment has been configured per Figure I-7 or Figure I-8.

 An RFDS (or at a minimum a directional coupler), whose loss is
already known, must be in line to perform the in–service calibration.

 Test equipment has been calibrated after 1 hour warm up.

 A short RF cable and two BNC–N adapters are available to perform
Cable Calibration.
