4. Example Four: Acquire Single Signal
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.
Operation steps are as follows：
Connect the channel probe to the detection point of the circuit.
Set the triggering: set F as （rising edge trigger） Triggering setting: DC Coupling.
Adjust horizontal time level and vertical scale to proper range.
Adjust proper triggering threshold.
Use “ ▲ ” or “ ▼ ”to choose Tr items in Measurement Area, press “M”; use “ ▲ ” or “ ▼ ”to choose SyncMode，
and then use “◄” or “►” to choose signal triggering mode, wait for the signal that match the triggering condition
to show up. If there is one signal reaching the preset threshold, it will be sampled and displayed on the screen. As
shown in the picture.
