HP E1434A 4-Channel 65kSa/s Arbitrary Source

The HP E1434A 4-channel Arbitrary Source is a C-size, one-slot, VXI module that provides stimulus for mechanical, acoustical, and electrical testing. Its versatile waveform types, performance, and tight integration with the HP E1432A and E1433A digitizers make it the ideal source for multi-channel measurements. Built-in sine and random noise waveforms save development time and offload computation and data movement chores from the host computer.

A single-channel version of the HP E1434A is available as an internal option (1D4) to the HP E1432A and E1433A digitizers.
