Abstract
A digitally synthesized source designed to provide two sinewave outputs with an accurately known adjustable phase shift in the second channel is described. A brief description is given of the bridge with which it will be used. The source requirements and design are discussed. A testbed wire-wrapped version demonstrates stability and noise of 0.5 p.p.m. (r.m.s.) over a 1-h period.<>
