3.4.4. "ANALYZING DETECTED SIGNALS" FUNCTION
The "MOBILE DEVICES MONITORING", "BASE STATIONS MONITORING", and "USER LIST"
functions make it possible to detect the presence of signals and estimate their levels; however, it
is impossible to determine the number of signals in each range and establish their frequencies
with absolute precision.
The "ANALYZING DETECTED SIGNALS" function is intended for a more precise study of the
detected signal in a range. It allows determining signal frequencies (in standard bands) and
analyzing them with OSCILLOSCOPE
It can be activated from any screen of the "WIRELESS COMMUNICATION" mode. To activate it,
use the
to select a table row with a detected signal, and press "ENTER".
Upon activation, the screen will look as shown in fig.19.
