will become visible. When this signal rises above the red line in the middle of the scope
view (the threshold level), an alarm will be triggered.
The threshold level is always situated around the value 50 and adapts itself to the highest
noise levels. When the Detection sensitivity is set to a lower value or in case of low
environmental noise, the threshold line will be a flat line.
Figure 28: Flat threshold line
When the Detection sensitivity is increased or when environmental noise is higher, the
threshold level will be raised for those frequencies where a stronger noise signal is
detected.
Figure 29: Partially raised threshold curve
Maximum detection sensitivity is reached when 50% of the threshold curve is flat and the
other 50% is raised. Adjusting the Detection sensitivity any further will not make the
system more sensitive for tags.
View Input X and Input Y 7.7.5.1.3
The scope views Input X and Input Y show the detected signals before they are fully
processed and filtered (raw data). These scope views are useful for determining the type
and amount of interference. In case of environmental noise, these views will show you
the effect of switching potential noise sources on and off.
The images below show a low noise environment versus a high noise environment.
