Trigger Mode Gated Sampling
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.
When the signal leaves the window from the inside to the
outside, the gate will start.
When the signal enters the window from the outside to the
inside, the gate will stop.
As this mode is purely edge-triggered, the signal within the
window at the cards start time does not trigger the board.
Channel window trigger for inner signals
The analog input is continuously sampled with the selected
sample rate. The upper and the lower level define a win-
dow.
When the signal enters the window from the outside to the
inside, the gate will start.
When the signal leaves the window from the inside to the
outside, the gate will stop.
As this mode is level-triggered, the signal inside the window
at the cards start time does trigger the board.
Channel window trigger for outer signals
The analog input is continuously sampled with the selected
sample rate. The upper and the lower level define a win-
dow.
When the signal leaves the window from the inside to the
outside, the gate will start.
When the signal enters the window from the outside to the
inside, the gate will stop.
As this mode is level-triggered, the signal outside the win-
dow at the cards start time does trigger the board.
