The HP/Agilent 3336C is a synthesized signal and level generator delivering precise frequency and amplitude control across R&D, production testing, and calibration applications. Built on single-loop, fractional-N synthesis architecture, it provides 11 digits of frequency resolution with phase continuity across its entire range. The instrument combines low-noise signal generation with flexible modulation and sweep capabilities, supported by HP-IB control and optional high-stability frequency reference for demanding metrology work.
