Keysight / Agilent / HP E1432A 16-Channel 51.2 kSa/s Digitizer Plus DSP (w/ Option 1D4)

The Keysight/Agilent/HP E1432A is a C-size, single-slot VXI measurement module delivering 16-channel data acquisition and onboard digital signal processing in a single card. It accommodates up to four 4-channel input assemblies, each digitizing at 51.2 kSa/s with 16-bit resolution. A 33 MHz Motorola 96002 DSP processor handles real-time signal processing, while up to 32 MB of DRAM and dual 128K word static RAM banks support high-speed computation and data storage. The module conforms to VXI revision 1.4 standards and integrates transducer signal conditioning, anti-alias filtering, and measurement computation. With Option 1D4, a 16-bit arbitrary source adds sine, random, and arbitrary waveform generation capability with output amplitude of 10 Vp nominal and 50Ω output impedance.
