1.2.2 Transmitter Specifications:
The power output is the following:
-
Nominal power output
– (2 ± 0,4)W;
-
Low power output
– ( 0,5± 0,08)W;
Attention!
When the radio is in use, it should be noted that the more output power is,
the longer the operating distance is. In nominal power output it is ranged up to 5 km and in
the low power output the operating distance is ranged up to 3 km. However, the more output
power is, the less operating time is, when the radio operates from the battery pack without
recharging, and the line masking is low too. It is advisable to select optimal power output
level when the radio is in use. Shorted antenna is intended to enhance the radio operation
while providing the communication over several hundred meters range.
1.2.3 Harm
onic suppression shouldn’t be more than 50 dB typical.
1.2.4 Frequency deviation of the transmitter while operating in the F1, F3 classes
should be
(5,6 ± 1,2) kHz.
1.2.5 Receiver Specifications:
Sensitivity of the receiver while receiving F3 class radio signal, is not more 0,5
µV for
12 dB SINAD.
Sensitivity of the receiver while receiving F1 class radio signal, measured from its
high-frequency input in test signal modulation of digital pseudorandom sequence (2
15
-1) and
error bit rate of ≤1×10
-2
is not worse:
-
0,5
µV while receiving data with the rate of 1200, 2400, 4800 bps
-
0,7
µV while receiving data with the rate of 9600 bps
Sensitivity attenuation of the signal receiver at the IF image is not less 60 dB, and at
the 1
st
IF is not less 70 dB.
Intermodulation selectivity of the receiver, measured by the three-signal method, is
not less 60 dB.
The receiver is equipped with the embedded squelch with operation threshold not
more than 1,5
µV.
1.2.6 The radio ensures performance control of the embedded fault detection
system, which detects malfunctioning unit accurate within the Standard Substitute Element.
1.2.7 The average number of frequency hops in the FHSS mode is 312.5 per
second.
