Chapter 5 Performance Checks
5.1 Introduction
This section covers performance checks used to verify that the radio meets published specifications. 
The recommended test equipment listed in the 
Chapter 4 approaches the accuracy of the 
manufacturing equipment, with a few exceptions. Accuracy of the equipment must be maintained in 
compliance with the manufacturer’s recommended calibration schedule.
5.2 Test Setup

5-4Performance Checks: Test Mode
When in the transmit test mode, DTMF modulation produces a sidetone in the speaker. All signaling 
types will continually modulate the transmitted signal for detection/measurement by external 
instruments.
5.3.3 Control Head Test Mode
The control head test mode is part of the diagnostics built into the radio and is entered through the 
front panel programming sequence. This test mode allows you to perform button and display tests to

Chapter 6 Radio Alignment Procedures
6.1 Introduction
This section describes both receiver and transmitter radio alignment procedures.
6.2 ASTRO XTL 5000 Tuner Software
A personal computer (PC) and Tuner Software are required to align the radio. Please refer to the 
CPS Programming Installation Guide (Motorola part number 6881095C44) for installation and setup 
procedures for the software. To perform the alignment procedures, the radio must be connected to 
the computer and to a universal test set, as...

Figure 6-2.  Tuner Main Menu
The alignment screens utilize the “softpot,” an analog SOFTware-controlled POTentiometer used for 
adjusting all transceiver alignment controls.
Each alignment screen provides the ability to increase or decrease the softpot value by using the 
slider or the spin buttons (
▲ and ▼), or by entering the new value from the keyboard. A graphical 
scale on the display indicates the minimum,...
