It’s the superiority and feature of digital oscilloscope to easily aquire non-periodic signals like impulsion and
sentus
. To aquire a single signal, you need a priori knowledge of it to set trigger level & trigger edge. E.g. if
impulsion is a TTL PWL logic signal,
trig level
should be set as 2V, trig edge as rising edge trig. If the signal is
not stable, it’s suggested to observe in a normal triggering mode to define trig level & trig edge.

and then use “◄” or “►” to choose single touch mode, wait for the signal that match the triggering
condition to show up. If there is one signal reaching the preset PWL, it will be sampled and displayed on the
screen. As shown in the picture.
