NI-5771

The NI5771 is a digitizer adapter module that, when combined with a PXI FPGA Module or Controller for FlexRIO, creates a high-speed digitizer that can simultaneously sample two channels at 1.5 GS/s or sample one channel at 3 GS/s with 900 MHz of analog bandwidth. You can use the NI5771 to do real-time processing and streaming of analog data with high-performance A/D converters. The Digitizer Adapter Module for FlexRIO is ideal for applications that require in-line data processing, high data streaming rates, and deployed high-performance solutions.
