Operation
Spectrum/ Waterfall Display
The G90S radio can display the spectrum diagram and waterfall diagram of
receiving signals and can quickly observe whether there is communication
signal on the neighboring frequency so that uses can quickly track and switch
frequencies and search the radio.
Spectrum display bandwidth: 48kHz
The spectrum signal strength value displays the accuracy: ±2dB
When the spectrum display is elevated, the spectrum top can not display or area
of the waterfall diagram display is white due to strong signals, the SCALE
parameter and the display effect can be adjusted:
1. Press [FUNC] key in a short time to enter the SCALE reference level
setting.
2. Rotate the main knob to adjust the SCALE value till the display effect is
appropriate.
3. Press the main knob in a short time, save and exit the setting interface.
■
The SCALE reference values shall be set gradually increasing from 1 to 10.
When the strong signals are observed, the SCALE values shall be turned up.
When the weak signals are observed, the SCALE values shall be turned down.
■
SCALE value in each frequency range can be independently set.
The second function meter of the [LOCK] key is as follows:
SCALE: reference level setting
AVE: average value setting
AVE average values shall be set gradually increasing from 1 to 10. The display
effect of the spectrum will be increasingly smooth with the setting increasing of
the average value. The average value can be set according to personal habit.
