b) Color palette
Here you can decide which colors are displayed depending on the signal strength. Not active for regular spectrum view.
c) FFT resolution
The FFT sharpness (spectral resolution) can be improved at the expense of refresh rate. This function is particularly
useful when analyzing strong carrier signals and carrier feed-through on adjacent bins has to be reduced at minimum.
Freq:
offers the best performance at the expense of a slight degradation of the signal amplitude accuracy and
refresh rate.
Time:
Selects the FFT algorithm of previous software versions (FFT with Hann window)
Mix:
Selects a polyphase FFT analysis with increasing window length (Polyphase FFT with quasi-flat-top
amplitude response)
6-3 Marker
A right mouse click feature is available within the spectrum / waterfall panel. Right click on up to eight frequencies, and
a small arrow appears. In waterfall mode, the arrow is situated where the signal waveform would be on the spectrum
