Leader 3222 Overview
The Model 3222 synthesized signal generator covers 100 kHz to 2.7 GHz. It provides 10-Hz resolution to 1.35 GHz and, thereafter, 20 Hz resolution to 2.7 GHz. Frequency accuracy is better than 0.05 ppm standard, and a 0.002 ppm time base is available as an option. A standby mode maintains reference timebase oven stability to eliminate warmup time when powering up. Operating choices include up to 100 setup programs in which carrier frequency, modulation modes and parameters, and output attenuation are preset. A precision output attenuator controls output from +13 to -133 dBm with 0.1-dBm settability. The output attenuator has mercury-wetted relay contacts to eliminate switching transients.
Modulation capabilities include seven modes with 14 simultaneous combinations to choose from. Included are pulse (GaAs FET), logic dc FM, and internal or external AM and FM. GPIB control is standard.
