       What data set size is used to calculate the FFT on the DS series of scopes?                                               
On our older scopes, the FFT is calculated using the displayed data set.
DS1000E/D/B/CA series scopes = 600 Data points

Our newer instruments use more:

The DS2000, DS4000, and DS6000 Scopes use 2048 data points from the waveform to calculate the FFT. 

The DS1000Z was updated to include 16384 points in its FFT when using the new MEMORY FFT mode.
