BER (Bit Error Rate) Measurement
1. The Panel Test Mode is used to measure the BER with
the TK-5400 (see 1. Panel Test.).
2. Select a filter to be measured (see Filter Mode.).
3. Select a frequency to be measured (see Test Fre-
quency.).
4. Select "15" for test signaling (see Test Signaling.).
(If there is no RF input signal, the display shows
".999999".)
5. Enter a standard input signal into the receiver as a stan-
dard 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".)
C4FM (APCO) Deviation Adjustment
1. The TK-5400 adjusts the deviation between High Devia-
tion ± 1800Hz and Low Deviation ± 600Hz for the C4FM
(APCO).
2. The Symbol Rate Pattern is used when adjusting the
High Deviation for the C4FM (APCO) (see Test Signal-
ing.). This test signal has a peak deviation equal to 2/π
1800Hz = 2827Hz.
3. The Low Deviation Pattern is used when checking the
Low Deviation for the C4FM (APCO) (see Test Signal-
ing.). This test signal has a peak deviation equal to 2/π
600Hz = 942Hz.
