Channel Trigger
Channel window trigger for entering signals
The analog input is continuously sampled with the selected
sample rate. The upper and the lower level define a win-
dow. Every time the signal enters the window from the out-
side, a triggerevent will be detected.
Register
SPC_TRIG_CH0_MODE
SPC_TRIG_CH0_LEVEL0
SPC_TRIG_CH0_LEVEL1
Channel window trigger for leaving signals
The analog input is continuously sampled with the selected
sample rate. The upper and the lower level define a win-
dow. Every time the signal leaves the window from the in-
side, a triggerevent will be detected.
Register
SPC_TRIG_CH0_MODE
SPC_TRIG_CH0_LEVEL0
SPC_TRIG_CH0_LEVEL1
Channel window trigger for long 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 signal leaves
the window before the pulsewidth counter has stopped, no
trigger will be detected.
If the pulsewidth counter stops and the signal is still inside
the window, the triggerevent will be detected.
