SRS DS360 — Ultra-low distortion output to 200 kHz

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.

Unlike conventional RC oscillators, the DS360 uses digital signal processing and a precision 20-bit D/A converter to provide better than -100 dB distortion over the audio frequency range.

With its DDS architecture the DS360 has the features and flexibility of a contemporary synthesized function generator.

Careful shielding and board layout keep the output noise to a minimum, making the DS360 the instrument of choice for audio research and development, manufacturing, and automated testing.

Low-distortion analog sources have impressive THD specifications but suffer with poor frequency accuracy and resolution. The DS360 delivers 0.0025 % frequency accuracy over its entire frequency range. It also boasts 6-digit frequency resolution from 1 mHz to 200 kHz, and a steady 25 ppm frequency stability. You can actually dial in 123,456 Hz from the front panel and have it mean something!
