Channel window trigger for long outer signals
The analog input is continuously sampled with the selected
sample rate. The upper and the lower levels define a win -
dow. Every time the signal leaves the window from the in -
side, the pulsewidth counter is started. If the signal enters
the window before the pulsewidth counter has stopped, no
trigger will be detected.
If the pulsewidth counter stops and the signal is still outside
the window, the triggerevent will be detected.
Channel window trigger for short inner signals
The analog input is continuously sampled with the selected
sample rate. The upper and the lower levels define a win -
dow. Every time the signal enters the window from the out -
side, the pulsewidth counter is started. If the pulsewidth
counter stops and the signal is still inside the window, no
trigger will be detected.
If the signal leaves the window before the pulsewidth coun -
ter has stopped, the triggerevent will be detected.
