Overview

Product overview

Key product information and technical features.

The NI-9775 provides four referenced single-ended analog inputs with simultaneous sampling, 14-bit resolution and a -10 V to 10 V input range. This C Series digitizer uses BNC front connections and has no differential analog input channels or analog input isolation.

The module supports finite-sample measurements up to 20 MS/s/ch, continuous measurement up to 4 MS/s, and waveform streaming at a lower sample rate. A built-in analog reference trigger supports capture of high-speed phenomena.
