5.4.2 Storing the Trigger

The threshold T in percent, defi ned as an envelope width (over and under) the last
cycle of signal V or A input signal. Its width W is calculated with the nominal mea-
surement range R for a channel (depending on the selected current sensor).
Example: Using the SR193 probe and a 2% trigger level, the
width would be 1000A x 2% = 20A. Therefore, a deviation of
± 20A will cause a transient event to be captured.
