NICAM AUDIO BIT ERROR RATE MEASUREMENT
For better evaluation of the Nicam signal audio quality the bit error
rate (BER) can be measured.
Example
To call bit error rate measurement:
Press
[SUBC]
Press the
[3]
button
If the quality of the DVB signal is so good that no bit error can be
detected,
BER=0.000
is displayed.
If the Nicam signal is too bad or no signal is received, the display
indicates
“Overfl ow”
.
DVB-C / DVB-T/H MER, BER AND OFFSET MEASUREMENT
[DVB]
After app. 1 second the audio carrier level is displayed.
LC display:
• Audio carrier level spacing - frequency: 5.5 MHz
• Audio carrier level: 58.5 dBµV
• Operating mode: Analogue cable TV
Release the
[1]

To measure audio carrier level spacing and level of TT2:
During the audio carrier display press the
[2]
button.
To measure audio carrier level spacing and level of Nicam audio
carriers:
During the audio carrier display press the
[3]
button.
The modulation error rate (MER), the bit error rate (BER) and the
carrier frequency offset can be measured to rate the digital reception
quality.
To call up DVB-C / DVB-T/H measurement:
In CABLE digital or Terrestrial digital reception mode press the
[DVB]
