Auto Snapshot
This feature allows you to automatically capture an FFT
Snapshot on the completion of each FFT. If Repeat is set to
“Yes”, then it creates a pseudo Time History. The time
interval between spectra Snapshots will equal the FFT
calculation time (see "Bandwidth" on page 12-3) multiplied
by the number of counts selected for Count Averaging. For
more detail on Snapshots, see "Snapshot" on page 12-11.
