The Agilent 3336C is designed for traditional synthesizer applications as well as R&D and production testing of systems or components. It features precision level control, high spectral purity, optional frequency stability of ±5 x 10-8/week, internal frequency sweep and numerous other user conceniences.

A single loop fractional-N synthesis technique allows synthesizer accuracy with 11 digits of resolution, with completely phase continuous frequency sweep over any of the instruments' frequency ranges.

Agilent attenuator technology coupled with custom designs in leveling loops and thermal converters produce amplitude accuracies of up to ±0.05dB. The fast leveling loop makes extremely flat sweeps possible at high sweep speeds.
