Agilent / Keysight E1429B VXI 20 MSa/s 12 bit Digitizer with Local Bus

The Agilent/Keysight E1429B is a single-slot C-size VXI digitizer module delivering 12-bit resolution at sampling rates up to 20 MSa/s for high-speed transient signal capture. Built for demanding test environments, this two-channel module combines flexible data acquisition with dual data paths—standard VXI bus and high-speed VXI Local Bus—to optimize throughput across different system architectures.
