Well, this was again pretty simple. And finally, we display the strength of each of
the 3 readings as vertical bars on the Y-axis:
Additionally, we have also adapted the width of each vertical bar to the width of
the respective
frequency range
of each radio application (the so-called
band-
width
): DECT only has 20MHz (1.880-1.990MHz=20MHz) of
bandwidth
, a very
small range. Amateur radio, in contrast, already uses a far higher
bandwidth
(2.320-2.450=130MHz) and so on.
Well, this wasn’t all that difficult, was it? We can now see ALL information con-
cerning these three signal sources.
In practice, this will look similar on the SPECTRAN display:
In this example, we also have 3
main signal sources
(from left to right):
Signal#1
=942MHz at -63dBm
Signal#2
=2.024MHz at -23dBm
Signal#3
=5.823MHz at -42dBm
