CHECKLIST B (Paragon-III) 
General Check out (part2 of 2) 
Paragon-III units are set and characterized at the factory to optimize performances.  
It is not recommended to try readjusting units unless it is really required.  
Misadjusting unit may result in significant performance losses. 
The proposed adjustments in the "IF NOT?" column below, should be tried ONLY if system data 
performance degradation is noticed combined with out of tolerance items.

MEASURE WITH 
IF NOT? 
Set the service monitor to generate on the selected receive frequency. Verify alternately for both receivers. 
The carrier should be modulated with a 1.0 kHz tone at deviation level specified below: 
12 dB SINAD 
(Dataradio wide band 
measurement method: no 
audio filtering) 
Set deviation to  ±8 kHz.  
 
Better than  -108 dBm  
including cable loss 
(Typically -109 to -110 dBm)
 
- Backplane correspond-
ing to the receiver be-
ing verified: J1 (RX1) 
or J5 (RX2),  
Pin 6 (see Figure 13, 
page 15) 
-  Service monitor  (IFR) 
set to SINAD 
-  IFR IF filter set to MID 
position or 300 kHz 
wide filter. 
 
Refer to section 5.2.2 
Receiver distortion  
(Dataradio wide band 
measurement method: no 
audio filtering)  
-  Set service monitor RF 
Gen output to –70 dBm 
-  Deviation level as per 
SINAD above. 
 
≤ 5.5 % 
(Typically < 3.5 %) 
- Backplane correspond-

Refer to section 5.2.2.5 for 
all models. 
Refer to factory technical 
support only if RX data 
performance degradation is 
noticed combined with out 
of tolerance RSSI readings.
