3.1 OVERVIEW AND MAINTENANCE INTERVALS
This chapter outlines the basic tests and adjustments required upon initial installation and thereafter at
annual maintenance intervals or whenever deterioration in performance indicates that adjustment may be
required. Units are delivered from the factory properly aligned and tested on the frequency range specified
at time of order. Adjustment beyond that described in this chapter is not required unless radio modules have
been tampered with or repaired. In such cases, we recommend complete factory re-alignment as special test
equipment is required. This chapter is intended for use by installation and maintenance personnel.
3.2 EQUIPMENT REQUIRED
The adjustments described below require the following equipment:
1. 13.3 VDC / 5A regulated power supply.
2. Radio service monitor (IFR1200 or equiv.).
3. Cable with SMA male connector to connect Integra-TR to the service monitor.
4. Integra Field Programming Software kit.
5. A PC with Windows 95 or later operating system to run the Field Programming Software.
6. Normal radio shop tools.
3.3 TEST POINT
For trouble shooting aid, there is one test point available at pin 4 of the power/analog connector (white
wire). This demodulated signal measurement is half the voltage read at the RSSI bar graph (found in the
Field Programming Software).
Note: the RX-TP mode must be selected (Analog Connector window) using the Integra Field Programming
Software.
3.4 BASIC TESTS / ADJUSTMENTS
Basic tests and adjustments to be performed are:
1. Transmitter power output
2. Transmitter frequency
3. Transmitter deviation
4. Carrier Sense
5. Demodulated signal level
6. 12 dB Sinad
7. Distortion
