说明

Stanford Research DS360 Ultra-low Distortion Function Generator Features: -10 mHz to 200 kHz range -< -100 dBc distortion (to 20 kHz) -Sine, square, white & pink noise -20 µVpp to 40 Vpp output range -Linear and log sweeps -25 ppm frequency accuracy -10 MHz reference input with option 3 - this unit does not have this option but I believe it can be added from Stanford Research. -Balanced & unbalanced outputs -RS-232 and GPIB Description: The performance of a low distortion analog source and the precision of direct digital synthesis (DDS) is combined in the DS360. With less than 0.001 % total harmonic distortion (THD), 25 ppm frequency accuracy, and a broad range of features including sweeps and bursts, the DS360 is the ideal source for audio frequency applications.
