Equivalent
Using equivalent sampling for a repetition signal can speed up effective
sampling
sampling rate than the maximum single-shot sampling rate.
(EQU SMPL)
Principle
Every time waveform data is captured, the time tn (n=1, 2, 3,...) after
trigger generation until data is sampled is measured and data is
overwritten taking account of relative time relationship.
This instrument implements 10 G equivalent sampling by measuring
the time with 100 ps resolution.
Example of measurement by normal sampling and Equ sampling for
approx.100 MHz sine wave
Norm sampling
Sampling in 5 ns period
Mainly used to
measure single-shot signal.

This Norm sampling example is
shown by Join ON.
Data pieces captured in 5ns
period are linked with a line.

Restriction on
equivalent sampling
With long memory, equivalent
sampling is not performed
even if Equ Smpl is set to ON.
