The Model 3363 resonant-modulator driver is a user-friendly single-frequency RF driver for operation with our electro-optic modulators (EOMs). It consists of a single-frequency source and RF power ampli?er in a compact package and is ideal for use with New Focus™ EOMs operating from 50 kHz to 2.0 GHz. (It can also be used with our broadband EOMs, but results in lower modulation depth).
