5. Trouble-Shooting and Testing
The checks described below should be done at time of installation, annual intervals, or whenever de-
terioration in performance is noted.

5.1 Equipment
Required
•
In-line wattmeter (5 W range) for the 1W-transmitter module as well as for the reflected power
and (100W range) for the power amplifier.
and (100W range) for the power amplifier.
•
Radio service monitor (IFR-120B with option 03: 30kHz IF filter or equivalent).
•
RG-214 or RG-223 cable with N-Type male connector to connect Paragon3 base station to the
service monitor.

Important note: Before proceeding make sure that the service monitor has been calibrated recently
and has warmed up for at least the time specified by its manufacturer.
and has warmed up for at least the time specified by its manufacturer.
Some reported frequency and deviation problems have actually been erroneous indications from ser-
vice monitors that have not adequately warmed up. This is particularly likely when field service is
done during winter months

5.2 Recommended Checks
A) After an installation (see Table 5)
1. Power-up LED Sequence
2. Transmit power output
3. Reflected power output
4. RF Link test between Paragon3 unit(s) and mobile unit(s) (PING test from the unit Web page

3. Reflected power output
4. RF Link test between Paragon3 unit(s) and mobile unit(s) (PING test from the unit Web page
as per paragraph 4.7.6.1 or PING test as per paragraph 5.3.3)
B) For annual maintenance & trouble-shooting (see Table 6)
Same checks as A) plus:
5. Carrier frequency error
6. TX Deviation
7. Low frequency balance
8. 12dB SINAD
9. Receiver distortion
10. Main RX and Aux. RX RSSI
11. Verify power supply connections & terminals torque settings (see paragraph 2.5.1.1.1)
