The Anritsu 69269A is a synthesized signal generator delivering phase-locked RF output across 0.01 to 40 GHz with output power spanning –125 dBm to +17 dBm in 0.01 dB steps. Built for defense electronics, microwave link testing, and RF design verification, it combines ultra-low phase noise (–100 dBc/Hz @ 10 kHz offset from 10 GHz) with flexible modulation and sweep architectures.
