The SPECTRAN devices offer 4 different OPERATION MODES:
- SPECTRUM analysis
- EXPOSURE LIMIT calculation
- AUDIO output
- Broadband PEAK-Detector (Powermeter)
(Option. Only 2025E Rev3 up)
You can change the operation mode at any time using the Enter-key.
5.1 Operation mode Spectrum analysis :
(The DISPLAY MODE status field shows “SPECTRUM”)
Now press the Enter key until the Display Mode sta-
tus field reads “ SPECTRUM ”. Should you have “good
reception” and a properly aligned antenna (this is impor-
tant!), you should now have results similar to those shown
in the image on the left. However, should the
big Main
display show “----” or “ -120 ”, no signal is being received
and you need to change your location or align the anten-
na differently. During every measurement, a
little dot
moves from left to right in the Graphics display . Only
when this dot reaches the right border , the current
measurement is finished and all readings are updated.
The Main display always shows the level of the strongest signal , “ -45 ” in our
example. The bigger this figure is (the closer it gets to “0” or a positive value),
the stronger the received signal (for example: “ -35 ” is much stronger signal
than “ -45 ” shown in our example).
