MAINTENANCE AND ADJUSTMENTS
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 / 2A regulated power supply.
2. Radio service monitor (IFR1200 or equiv.).
3. Cable with SMA male connector to connect Integra-H to the service monitor.
4. Integra Radio Service Software (RSS) kit.
5. A Win/95 PC or better to run the RSS.
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 INTRSS and
INTDIAG programs.
Note: the RX-TP mode must be selected (
Analog Connector
window) using the Integra RSS.
3.4 BASIC TESTS/ADJUSTMENTS
Basic tests and adjustments to be performed are:
1. Transmitter power output
2. Transmitter frequency
3. Transmitter deviation
4. Demodulated signal level
5. 12 dB Sinad
6. Distortion
