With high-speed digitizers, triggering capability is as important as input signal conditioning. The NI 5114/5122/5124/5142 provides flexible, high-precision, low-jitter triggering features.
The NI 5114/5122/5124/5142 has three fundamental analog trigger paths:
The following figure shows the analog trigger paths for the NI 5114/5122/5124/5142.
Unlike the input channels (CH 0 and CH 1), the external trigger channel uses a fixed input range and impedance to give a higher bandwidth for triggering the digitizer. Signals that travel through the external trigger channel are not digitized.
