6.12.4 COFDM - RF Overview (VB250)
The RF parameters and measurements list gives a status overview of all monitored
COFDM frequencies from the selected RF input. The parameters and measurements in
this list refer to the last completed monitoring period or, for a stream currently
monitored, the current monitoring period.
List of RF parameters and measurements:
Frequency:
The stream frequency that the associated parameters apply
to
Channel spacing:
The channel bandwidth
Spectrum
inversion:
Spectrum inversion:
normal
or
inverted
TS sync:
Transport stream sync:
yes
or
no
Min level:
The minimum RF signal level
Max level:
The maximum RF signal level
Min SNR:
The minimum signal to noise ratio
Min MER:
The minimum calculated modulation error ratio
Max pre FB:
The maximum bit error rate before forward error correction
Max post FB:
The maximum bit error rate after forward error correction
1
PPS lock:
An indication of reference signal lock. The value may be
'Locked' or 'No lock'.
Max SFN drift:
The maximum SFN drift (in uS) detected during the
monitoring period
