Channel Trigger Trigger modes and appendant registers
Channel spike trigger (slope trigger)
The analog input is continuously sampled with the selected
sampling rate. If the difference between two samples is
higher than the programmed value (in either positive or
negative direction) the triggerevent will be detected.
This slope triggered channel trigger mode is ideally suited
for monitoring of power supply lines and triggering on
noise or spikes.
Register Value Direction set to Value
SPC_TRIG_CH0_MODE 40610 read/write SPC_TM_SPIKE 200h
SPC_TRIG_CH0_LEVEL0 42200 read/write Set the difference between two samples relatively to the channel’s input
range for positive slopes.
board dependant
SPC_TRIG_CH0_LEVEL1 42300 read/write Set the difference between two samples relatively to the channel’s input
range for negative slopes.
