The
Internal Auto Level
trigger mode always returns a trace and triggers off the incoming signal. However, if a signal
is not present it will return a noise trace. Shown below is an example of a complex waveform being measured using
internal triggering (AM = 90%, 1 kHz).
NOTE:
An incoming pulse must be on at least 0.20 usec followed by at least 1 usec of off time for the sensor to
properly trigger.
