NI 9775, 4-Ch, +/-10 V, 20 MS/s/ch, Digitizer C Series Module (784539-01)

±10 V, Up to 20 MS/s/ch, 14-Bit, 4-Channel C Series Digitizer Module
The NI-9775 provides referenced single-ended analog inputs with two timing modes for applications such as fault detection in electrical transmission lines or structural failure events. You can use the NI-9775 to measure finite samples up to 20 MS/s/ch to capture fault detections or to measure continuously at up to 4 MS/s. You also can use the built-in analog reference trigger to assist with high speed phenomena. Additionally, the NI-9775 supports waveform streaming at a lower sample rate.
