GetLNBOffset

Usage: GetLNBOffset
This command displays the current LNB frequency offset in the receiver, calculated as a
result of LNB drift tracking. The receiver applies this offset to the frequency of the DVB
Carrier, to obtain the actual tuning frequency for the receiver, thus compensating for LNB's
whose output frequency drift due to temperature or aging. The receiver tracks this drift
every time it acquires lock to a DVB Carrier. This command takes no parameters. The
output is formatted as follows (with appropriate values substituted):
LNB Offset: 0 or ±xxxxxxx Hz

ResetLNBOffset

Usage: ResetLNBOffset
Note that this command is available only to the admin user.
This command resets the current LNB frequency offset in the receiver back to zero. This
command takes no parameters.

GetRFMetrics

Usage: GetRFMetrics [-r n]
This command displays the current RF metrics information. The optional -r n parameter
indicates repeat mode. In this mode, the metrics information will be output continuously
(every n seconds) until a key is pressed on the controlling terminal. If this parameter is
omitted, the RF metrics information will be displayed only once. The following information is
displayed (all zeros or numeric values substituted):
If the receiver is NOT locked to a DVB Carrier:
Signal Level: 0 %
Signal Quality: 0 %
RS Uncorrected Packets: 0
Carrier to Noise: 0.0 dB
Eb/No: 0.0 dB
Viterbi BER: 0.0
If the receiver IS locked to a DVB Carrier:
Signal Level: xxx %
Signal Quality: xxx %
