Transients

 

 

Detection of voltage transients

> 40 ns

Useful bandwidth input 1 (with test leads TL24)

DC to 1 MHz

Reference signal

V rms, Hz

After START, the V rms and frequency of the signal are measured.

From these data a pure sinewave is calculated.

 

Detection when transients exceed specified voltage level (selectable)
