BER (Bit Error Rate) Measurement
1. The Panel Test Mode is used to measure the BER (Refer
to “Test mode operation features” described on page
56.).
2. Select ”26” for test signaling (Refer to “Test Signaling”
described on page 57.).
When “26” is selected for the test signaling, the fi lter is
automatically selected to “P25”.
(If there is no RF input signal, the display shows
”500000”)
3. Select a fi lter (Refer to “Filter Mode” described on page
57.).
4. Select a test frequency (Refer to “Test Frequency” de-
scribed on page 57.).
500000
5. Measure the BER (Bit Error Rate) using the digital radio
tester. Enter a standard input signal into the transceiver
as a standard tone test pattern.
6. Adjust the input signal level to achieve the standard bit
error rate (BER).
(For example, if the BER is 5%, the display shows
”050000”.)
050000
C4FM (P25) Deviation Adjustment
1. The transceiver adjusts the deviation between High De-
viation ±1800Hz for the C4FM (P25).
2. The Symbol Rate Pattern is used when adjusting the
High Deviation for the C4FM (P25) (Refer to “Test Signal-
ing” described on page 57.). This test signal has a peak
deviation equal to
π
/2 1800Hz = 2827Hz.
