The Stanford Research Systems DS360 is a low-distortion synthesized function generator that combines the low-distortion performance of an analog source with the precision of direct digital synthesis (DDS). With less than 0.001% total harmonic distortion, 25 ppm frequency accuracy, and a broad feature set that includes sweeps and bursts, it is designed as a source for audio frequency applications.
A function generator produces known, controllable test signals used to stimulate a device under test so its response can be measured. The DS360 is built for audio research and development, manufacturing, and automated testing. Its two-tone signal supports intermodulation distortion (IMD) testing, generating standard two-tone formats including SMPTE, DIM, and CCIF.
ValueTronics stocks and holds its own inventory in a 20,000 square foot secure warehouse at 1675 Cambridge Drive, Elgin, Illinois. Every pre-owned unit is inspected and functionally verified in-house before it ships, while new units ship factory-sealed exactly as received from the manufacturer.
