Page 14: Example Four: Acquire Single Signal
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. -
