      Hi Edgar,

      In that particular combination (triggered average spectrogram, trigger controls *one sweep* i.e. one screen written on the spectrogram), every scan line on the screen has its own average buffer. The averaging operates on signal powers (or energies, power * time), and is implemented as a simple integrate-and-dump filter.
      When the number of averages is limited, there's no moving-average (would cost an awful lot of memory) but a simple leaky integrator. Whenever the average counter reaches the programmed value, a part of the integrated energy is discarded (50 percent) and, for example, the average counter is divided by two.

      All the best,
         Wolf .

      Hi Wolf,

      With triggered averaging, what is the algorithm that is used?
