echo "graph_title Carrier/Noise Ratio"

echo "graph_vlabel dB"

echo "graph_scale no"

echo "graph_info Calculated carrier/noise ratio of the signal. To avoid data errors, the decoding of a received signal requires a minimum C/N ratio that depends on the FEC rate."

echo "graph_args --base 1000"

echo "graph_title Carrier Frequency Offset"

echo "graph_vlabel MHz"

echo "graph_scale no"

echo "graph_info Incoming signals from the LNB are subject to frequency tolerances, thus check the 'CFO Error' under menu item 'Status>Tuner'. This value represents the margin by which the entered frequency deviates from the actual frequency. In order to maximize reception quality the CFO error should be minimized."
