Product Overview
The Agilent E1418A is a configurable 8 or 16-channel 16-bit D/A converter module optimized for VXI-based modular test systems. It supports fully independent channel configuration, with each channel switchable between precision voltage and current output modes via terminal block jumpers. The module features software-controlled calibration to maintain long-term measurement accuracy and low signal noise below 2 mV rms across the full bandwidth. It supports both individual single-channel updates and synchronous full-channel simultaneous output, eliminating timing deviation in multi-channel analog signal simulation. Available in isolated and non-isolated output variants, it adapts to diverse test environment requirements. Its register-level programming enables fast backplane data access, delivering reliable, repeatable analog output for precision automated testing and industrial analog control simulation scenarios.
