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.
Ultra-Low Distortion and Noise
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.
Frequency Stability
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 has 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!
