Signal Level and Signal Quality
The Signal Level and Signal Quality of the incoming signal are displayed both numerically and
graphically using bar graphs.
The Signal Level is associated with the RF input signal level. The Signal Level display is continuously
updated to indicate the relative strength of the received RF input signal. It is displayed in the range from
0 to 100.
The Signal Quality is associated with the Bit Error Rate (displayed in the range from 0 to 100). The
Signal Quality is continuously updated to indicate the relative quality of the received RF input signal.
Viewing Advanced RF Diagnostics
The Advanced RF diagnostics screen is primarily used by Cisco customer support for information
purposes only, if needed.
Proceed as follows to view the Advanced RF Diagnostics screen:
From the RF Status screen, press the blue button (Adv RF).
Modulation System Indicates the modulation type of the received signal.
PV BER Indicates the PV (Post-Viterbi) BER of the received signal (DVB-S
only).
LDPC BER Indicates the LDPC (Low-Density Parity-Check) error rate of the
selected input (DVB-S2 only).
PER Indicates the current PER (Packet Error Rate).
C/N Margin Indicates the current Carrier-to-Noise Margin of the received signal,
in dB. The Carrier-to-Noise margin is the actual distance that C/N
is from the noise threshold.
Signal Lock Indicates the current signal lock status for the input.
Rolloff Mode Indicates the rolloff mode of the incoming signal. The default is set
to Auto.
Rolloff Factor Indicates the rolloff factor of the incoming signal.
LNB PS Status Indicates the current LNB connection status (No Load, Overloaded,
OverTemp, Short Circuit, Disabled, Normal, or N/A).
