Low Signal Quality Threshold
The threshold value for low signal quality can be set in
order to monitor the current signal quality. It is displayed as
a value between 0 and 100 in percent. If the current signal
quality value drops below the signal quality threshold value,
the Low Signal Quality Level warning is output.
The function can be deactivated by setting the threshold
value to zero.
Current Signal Quality
The current signal quality is displayed as a value between
0 and 100 in percent. If no valid signal quality is available,
the value is set to 255.
Signal Quality Bad
The status of the signal quality is displayed as a Boolean
value. If the value is TRUE, the signal quality is below the
threshold value; if the value is FALSE, the signal quality is
equal to or greater than the threshold value. This status is
visualized by an orange LED that illuminates if the value is
TRUE.
