Frequently Asked Question

What are the advantages of using a DDS?

DDS arcihtecture offers microhertz tuning resolution of an output frequency and subdegree phase tuning capability, all under complete digital control. They offer extremely fast “hopping speed” in tuning output requency (or phase), phase-continuous frequency hops with no over/undershoot or analog-related loop settling time anomalies. The DDS digital architecture eliminates the need for the manual system tuning and tweaking associated with component aging and temperature drift in analog synthesizer solutions. The digital control interface of the DDS architecture facilitates an environment where systems can be remotely controlled and minutely optimized, under processor control. When utilized as a quadrature synthesizer, a DDS affords unparalleled matching and control of I and Q synthesized outputs.
