The performance of a low distortion analog source and the precision of direct digital synthesis (DDS) is combined in the DS360 from Stanford Research Systems. With less than 0.001% total harmonic distortion (THD), 25ppm frequency accuracy, and a broad range of features including sweeps and bursts, the DS360 is the ideal source for audio frequency applications.
Features:
- 10mHz to 200kHz frequency range
- <-100dBc distortion (to 20kHz)
- Sine, square, white and pink noise
- 20μVpp to 40Vpp output range
- Linear and log frequency sweeps
- 25ppm frequency accuracy
- Balanced and unbalanced outputs
- RS232 and GPIB interfaces
Unlike conventional RC oscillators, the DS360 uses digital signal processing and a precision 20-bit D/A converter to provide better than -100dB distortion over the audio frequency range. With its DDS architecture the DS360 has the features and flexibility of a contemporary synthesised 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 boards 6-digit frequency resolution from 1mHz to 200kHz, and a steady 25ppm frequency stability.
The DS360 generates clean sine waves and square waves, as well as a two-tone signal for IMD testing. The two-tone signal is defined as either two sine waves, or a sine wave and a square wave. Both frequency and amplitude are independently set for the two waves allowing standard two-tone formats like SMPTE, DIM and CCIF to be generated. In addition to standard waveforms, the DS360 outputs white noise, pink noise and band-limited white noise.
