The available options are:
• Signal Quality – Qualitative indicator of the received signal C/N relative to the maximum
C/N that can be measured without forcing the receiver to saturation.
The signal quality is calculated by: SQ[%]=C/N [dB]/36 *100

• C/N – Shows the Carrier to Noise ratio.
• Eb/N0 – Received signal Eb/N0 measurement
• Link Margin – Estimated C/N of the received signal relative to the C/N in EN 300-421 for
a given FEC rate
• BER – Uncorrected FEC bits errors. BER is measured over 10
7
symbols.
• Frequency Tune – The value is dependent on the mode selected in

 Freq Drift Compensation (see Section 6.2).
• When Frequency Drift Compensation is set On, the value of the frequency
tune displays the frequency of the incoming signal after frequency offset is set
Off.
• When Frequency Drift Compensation is set Off, the value of the frequency
tune displays the actual frequency.
NOTE
Displayed frequencies are L-Band frequencies.
