AutoTune for Motorola APX Series Radios User Guide

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 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

(FCT-1365) for an overview and basic operating instructions for AutoTune itself.

2.1. Supported Models

The following Motorola APX Series radio models are supported:

•APX 900

•APX 1000/1000i

•APX 1500/1500 Enhanced

•APX 2000

•SRX 2200

•APX 2500

•APX 4000/4000Li

•APX 4500/4500Li/4500 Enhanced

•APX 6000/6000Li/6000XE/6000 Enhanced

•APX 6500/6500 Enhanced

•APX 7000/7000XE

•APX 7500

•APX 8000/8000H/8000XE

3. Motorola APX Portable Radio Test Setup

Before servicing a radio with AutoTune, ensure the analyzer is running the current

system software version. Each system version release contains issue resolutions and/or

new/enhanced features.

•On the analyzer, navigate to Settings > About… Note the System version shown.

•Browse to the Freedom software upgrades webpage:

https://freedomcte.com/upgrades/

•If the first Current System Version shown on the webpage is more recent than

the analyzer System version, follow the webpage instructions to download and

apply the current system version software to your analyzer.

To perform the test and alignment procedures, the APX Portable radio must be

connected to the R8000 Communications Systems Analyzer as shown in Figure 3-1.

APX Portable Test Setup Diagram.

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. Cable Sweep

Every RF cable connected between a radio under test and the analyzer attenuates the

signal propagating through it. The amount of attenuation varies by several factors such

as operating frequency, cable length, and cable type. Ensuring this attenuation is

accounted for by the analyzer is important to the accuracy of several tests and

alignments, primarily power tests.

Sweep the RF cable used between the Radio and Analyzer, label the RF cable with the

stored cable sweep name, and enable the Cable Sweep feature in the analyzer System,

System Settings… menu. Refer to Application Note FCT-1017 Utilizing Cable Sweep on

the Freedom Communications System Analyzer for instructions on how to perform a

cable sweep.
