In Fig.43:
1 - difference spectrum obtained during the last measurement cycle (lilac color)
2 - difference spectrum obtained in previous measurement cycles (claret color)
3 - indicator of DIFFERENTIAL mode turning on (light field of the "F3")
Available actions:
signal analysis at a fixed frequency;
search for signals in the AUTOMATED mode;
gain setting (x1, x2, x4);
possibility of using an attenuator (20 dB).

For the mode turning off (return to the PANORAMA mode)
press "F3". The field of the "F3" will
become more dark.
Changes to the span and attenuator settings made in the DIFFERENTIAL mode are saved when
exit to the PANORAMA mode.
5.2.5. SIGNAL ANALYSIS AT A FIXED FREQUENCY
The function is designed to study signals in the PANORAMA mode or in the DIFFERENTIAL
mode and allows to tune to the frequency of the detected signal, listen to the demodulated signal
and examine it using an oscilloscope.
Turning on is carried out from the PANORAMA mode or from the DIFFERENTIAL mode.
Using the or
buttons, set the marker on the signal and press "ENTER".
The screen is shown in Fig.44.
