1. Introduction
The Freedom Communication Technologies 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 for supported radios by AutoTune. This document is restricted to radio-
specific information for Motorola ASTRO® XTL™ Series and ASTRO® XTS™ Series
two-way radios.
Please refer to the R8000 Series Communications System Analyzer Owner’s Manual
(CG-1365) for an overview and basic operating instructions for AutoTune itself.

3. Motorola ASTRO® XTL™ Series Radio Test Setup
In order to perform the test and alignment procedures, the ASTRO® XTL™ Series radio
must be connected to the R8000 Communications Systems Analyzer as shown in the
figure below. Use of USB radio programming cables indicated are required to perform
all tests.
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.
3.1. ASTRO® XTL™ Series Test Setup
Refer to the diagram below for the proper test setup.

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 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 adjusts 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 output level defined by the radio itself. The final results are
written to the log file.

TX Power Out 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 align the radio power output level across the radio band as
specified by the radio 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.

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

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
