Testing a radio
After tuning the radio, it is required to test the digital RF signal.
Transmitting
Step 1
Open the Tuner software and go to “TEST -> TX -> Transmit BER (0.153)”.
Step 2
Select the channel to be tested and select “High Power” in “Parameter”.
Step 3
Set the Aeroflex 3920 parameters as follows:
Freq: Be consistent with the frequency to be tested.
STD IB 511(153)
Step 4
Click the “Transmit On” button.
Step 5
View all
the tested
items on the Aeroflex 3920
and make sure they satisfy the following requirements
.
Frequency Error
≤
100 Hz
Transmit Power: 2.5
±
0.2 W
FSK Error
≤
5%
Magnitude Error
≤
1%
Receiving
Step 1
Open the Tuner software and go to “TEST -> RX -> Receiver BER (0.153)”.
Step 2
Select the frequency to be tested.
Step 3
Set the Aeroflex 3920 parameters as follows:
Freq: Be consistent with the frequency to be tested.
STD IB 511(.153)
Lvl: -116.0 dBm
Step 4
Click the “Start” button.
The average error rate is less than or equal to 5%.
