Getting started with EDACS radio testing

Testing of EDACS radios is made quick and easy using the

IFR 2945B Communications Service Monitor. A step by

step guide to testing EDACS radios is given.

Introduction

The IFR 2945B Communications Service Monitor is ideal-

ly suited to the testing of trunking radios. It has an exten-

sive array of built-in tests, allowing verification of radio

performance, and rapid fault diagnosis.

Page 2 Trunked radio 12.5 kHz. Traditional two-way radio systems such as PMR (Private Mobile Typically, EDACS systems with a frequency set in the region of Radio) have used a system where a group of users have one 900 MHz operate at 4800 baud and other systems operate at channel allocated, with this channel possibly in use by other 9600 baud, so if the data rate is unknown, you can use this as a groups.

Page 4 If this login occurs, then the set-up information for the control channel is correct. If it doesn't, then there are several things that might be wrong. First, ensure that the frequency information for the system in the EDIT CURRENT menu screen is correct. Other things to check are the data rate and the Tx polarity.
Page 5 ING tests, in addition to the signalling, properties of the RF part of the radio, such as power, frequency and low speed data deviation. BRIEF TESTING and COMPREHENSIVE TESTING both test the audio properties of the radio and require audio break-out access www.aeroflex.com For the very latest specifications visit...
Page 6 If you have a any test, you don't release it until the 2945B Communications microphone with PTT switch (Aeroflex part number IFR Service Monitor prompts you to, since some of the tests rely on 44991/145) plugged into the accessory socket on the front panel this.

Page 8 is even at the limits of the 300 kHz filter bandwidth. Remote control The 2945B has remote control facilities available both from the built - in RS232 serial interface, as well as the optional GPIB (IEE488.2) interface. It also features a built in MI-BASIC interpreter, for user defined programs which can be downloaded from a PC.
