NI-9775

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.

Applications and Use Cases of NI-9775

The NI-9775 C Series Encoder Input Module is a high-speed encoder input module designed for precise motion measurement, position tracking, and real-time feedback control in CompactDAQ and CompactRIO systems. It is widely used in applications where accurate timing, synchronization, and high-resolution motion data are critical.
