The Keysight (Agilent) E4432B is a synthesized signal generator delivering precise RF signal generation from 250 kHz to 3 GHz. It combines low phase noise, excellent spectral purity, and flexible modulation capabilities—making it suited for R&D, manufacturing, and quality assurance environments where signal accuracy and stability are non-negotiable. The instrument features 1 Hz frequency resolution, output power spanning −130 dBm to +13 dBm, and internal modulation waveforms across AM, FM, and pulse modes. Fast switching (<10 ms) and sub-millisecond settling times enable rapid test sequences without sacrificing measurement confidence.
