Analogic DBS902 14-Bit Waveform Digitizer Module

The Analogic DBS902 is a 14-bit waveform digitizer module engineered for high-speed signal acquisition in demanding measurement environments. It functions as a plug-in component for the Analogic DBS9900 VXI C-size Dual Instrument Carrier, enabling dual-module configurations within a single chassis slot. The DBS902 delivers 80 MHz sampling with 2 MS of acquisition memory, 40 MHz typical bandwidth, and signal integrity suitable for scientific research, medical imaging, and industrial test applications.
