The Anritsu 69097B is a synthesized CW generator delivering ultra-low phase noise across 0.01 GHz to 65 GHz. Purpose-built for radar, communication systems, and precision laboratory testing, it combines exceptional SSB phase noise performance with spurious signal suppression required for sensitive measurements. The instrument features fast phase-locked step switching, leveled output down to –120 dBm in 0.01 dB resolution, and optional frequency stability to 5 × 10⁻¹⁰/day with aging. Its compact 13.3 cm height fits A.T.E. rack configurations while maintaining full frequency and power sweep capabilities across the entire band.
