4. Place the cursor within the RF zone and
configure the analyzer as follows:
14-3 BER TESTING THE RADIO
TRANSMITTE
R (Monitor mode)
14-3.1 Radio in BER Test Mode
This application example describes the transmitter
test for radios that have BER test capability. The
transmitter must have the capability of transmitting
an unencrypted V.52 BER test pattern.
Performance of this test requires the analyzer to
operate in monitor or duplex mode, and monitoring
a test signal transmitted by the radio under test.
5. Configure the radio under test to BER Test
mode. Consult your radio maintenance
manual for specific instructions. Reset the
analyzer frequency to the BER Test
frequency of the radio.
When testing the transmitter, the radio generates a
test signal. The analyzer measures the transmitted
BER, frequency error, and power level of the signal
transmitted by the radio under test.
6. Monitor the radio's received BER. Reduce
the analyzer's output level until the radio
measures a BER corresponding to
sensitivity threshold. Consult your radio’s
maintenance manual for the receiver
sensitivity specification.
Consult the radio maintenance manual, as specific
test frequencies may be specified for BER test of
your equipment.
1. Connect the RF input/output of the radio
under test to the RF I/O port of the analyzer
as shown in figure 13-4. Consult the radio
maintenance manual to determine the
appropriate test port.
