(2) Menu F2 : Sets Overlap/Disc (Discrete) for the statistics processing extraction mode.
Selects one of two modes: Discrete mode that outputs statistics processing results for collected data and Overlap mode
that outputs statistics processing results for each data sample. Fig. 4-29 shows the two modes.

(b) Statistics processing in Overlap mode
*1
The acquisition time is generated outside of the acquisition when acquisition processing Auto is set (max : 50 ms).
*2 The measurement time is determined from the frequency of the input signal and the measurement resolution.
