Agilent/Keysight Z2403A

The Agilent/Keysight Z2403A is a signal simulation component engineered for high-performance electronic test applications requiring accurate waveform generation and RF modulation. Operating within configurable system architectures, the Z2403A integrates with arbitrary waveform generators and RF signal sources to produce complex modulated signals across broad frequency and bandwidth ranges. It supports phase-coherent multi-channel outputs suitable for radar, communications, and distortion analysis test scenarios.
