1. Introduction
The General Dynamics R8000 Series Communications Systems Analyzer AutoTune™
(hereafter “AutoTune”) is designed to provide an automated test and alignment solution
for supported two-way radios.
2. Scope
This document is intended to provide information regarding the tests and alignments
performed by AutoTune for Motorola APX™ portable and mobile two-way radios. This
document is restricted to radio-specific information.
Please refer to the R8000 Series Communications System Analyzer Owner’s Manual
(CG-1365) for an overview and basic operating instructions for AutoTune itself.

AutoTune™ User Guide
3. Motorola APX™ Portable Radio Test Setup
In order to perform the test and alignment procedures, the APX™ Portable radio must
be connected to the R8000 Communications Systems Analyzer as shown in the figure
below.
Make certain that the radio under test is configured as described in the
corresponding diagram before attempting to perform an alignment or test.
Failure to do so may result in poor radio performance and/or damage to the
analyzer or radio equipment under test.

APX™ Test Setup
Refer to the diagram below for the proper test setup. Note that the correct setting for
each RLN4460 test set control is highlighted in yellow.

4.1.1. Alignment
The radio is placed into Test Mode at the highest TX Test Frequency and commanded
to transmit. Using a best linear fit algorithm, two frequency error measurements are
taken at two different radio softpot values. These frequency error measurements are
used to calculate the softpot value which minimizes frequency error. After programming
this new softpot value into the radio, the radio softpot is fine tuned until minimum
frequency error is detected. The frequency error is compared against test limits and the
final results written to the log file.

4.2.1. Alignment
The TX Power Out alignment is composed of two parts: Power Characterization Points
tuning and TX Characterization tuning. Power Characterization Points tuning is
performed first, and only during alignment; it is not performed during a test.
Power Characterization Points tuning adjusts the characterization points to account for
the variability of the power detection circuitry between radios. The radio is placed into
Test Mode and commanded to transmit at the first Test Frequency. The output level is
measured and then adjusted until near to a band-specific output level defined by the
APX™ Tuner software help file.

Power Characterization tuning characterizes the power output level of the radio. The

Test Frequency, the output level is measured at two different points for each TX Test
Frequency. These measurements are used to calculate and program power coefficients
use to normalize the radio power output level across the radio band as specified by the
radio’s basic service manual. After the alignment is complete, the power output level is

The radio is placed into Test Mode at the highest TX Test Frequency and commanded
to transmit. The radio generates an 80 Hz modulation tone and the deviation of this tone
is measured with the analyzer. The radio then generates a 3 kHz modulation tone and
the deviation of this tone is measured with the analyzer. The radio softpot is adjusted
until the deviation difference between the first and second tones is as small as possible.
This adjustment is performed for each TX Test Frequency and the percent difference is

Note: Throughout this section are references to Test Frequency that are band and

respective radio service manual. See the References section for more details.
Note: All analyzer Mode settings are Standard unless otherwise indicated.
Dual-Band: Some Motorola APX™ Mobile radios are dual-band capable. Additional
notes for radio models configured with two bands are included in the following sections.
If the radio under test is configured with a single band, these notes are not applicable.
Dual-Band: Dual Band equipped radios have two RF connectors at the rear of the
radio. They are labeled on the top and on the rear of the radio to identify which band
they should be used with. During most tests and alignments, it will be necessary to
change the test setup cabling to test both bands. The test operator will be prompted to
connect the RF cable to the appropriate RF Output port on the radio.

to transmit. The frequency error is measured by the analyzer and compared to test
limits. The final results are written to the log file.
Dual-Band: This test is only performed at a single test frequency. The test frequency
is the highest test frequency for the highest frequency band.

6.2.1. Alignment
The TX Power Out alignment is composed of two parts: Power Detection Calibration
and TX Power Out. Power Detection Calibration is performed first, and only during
alignment; it is not performed during a test.
Power Detector Calibration tunes the radio power detector to minimize the power output
variation across radios. The radio is placed into Test Mode and commanded to transmit
at a mid-band Test Frequency. The output level is measured and then adjusted until
near to a band-specific target output level supplied by the radio. The final results are
written to the log file.
Dual-Band: This alignment is performed consecutively for all test frequencies in both
bands.

Power Characterization tuning characterizes the power output level of the radio. The
radio is placed into Test Mode and commanded to transmit. Beginning at the lowest TX
Test Frequency, the output level is measured at two different points for each TX Test
Frequency. These measurements are used to calculate and program power coefficients
use to normalize the radio power output level across the radio band as specified by the
radio’s basic service manual. After the alignment is complete, the power output level is
measured again at each TX Test Frequency and compared against test limits. The final
results are written to the log file.
Dual-Band: This alignment is performed consecutively for all test frequencies in both
bands.

The radio is placed into Test Mode at the highest TX Test Frequency and commanded
to transmit. The radio generates an 80 Hz modulation tone and the deviation of this tone
is measured with the analyzer. The radio then generates a 3 kHz modulation tone and
the deviation of this tone is measured with the analyzer. The radio softpot is adjusted
until the deviation difference between the first and second tones is within test limits. This
adjustment is performed for each TX Test Frequency and the percent difference is
compared against test limits. The results for each TX Test Frequency are written to the

The purpose of this procedure is to verify that the squelch circuit operation performs as
expected, blocking noise but allowing stronger signals to be heard. The analyzer is
setup as specified in this section’s Analyzer Configuration table. The radio is placed into
Test Mode at the lowest RX Test Frequency. The radio audio output level is tested and
if insufficient to measure the unsquelched condition the volume is increased. Beginning
at -125 dBm, the analyzer output level is slowly increased until the radio unsquelches

alignment.
Possible Cause(s)
Serial link corruption.
Analyzer disk
corruption.
Loose HKN6163_

Motorola CPS

setting.
APX Family CPS
Transmit Power
Level settings limiting
radio output power.
DC Power supply
current limiting
preventing portable
radio from getting
adequate current.
Possible Solution(s)
Retry communicating with the
radio after each of the following
steps:
• Power cycle the radio.
• Restart the analyzer.
Contact General Dynamics
technical support.
Verify cable connection is OK.
Use Motorola CPS software to set
Radio Wide, Advanced, Ignition
Switch setting to “Blank”. This
setting lets radio power up for
testing without an ignition signal
present. Be sure to return this
setting to its original value when
testing completed.
Using APX Family CPS, adjust
Codeplug Configuration

Power Level settings to factory
defaults. This change lets radio
output expected power levels for
correct AutoTune TX Power Out
testing and alignment.
Adjust DC power supply current
