Single Mode
In single mode it is possible to freeze the current and voltage immediately after
turn-on. To capture this event, the SINGLE timebase mode is used. In SINGLE
mode a waveform is captured once, based upon a certain trigger event on one
of the input signals. To capture a turn-on event the current on input [2] makes a
good trigger. At power-on the current increases , causing a well-defined trigger
condition.
