Abstract
The system for four-terminal pair intercomparison of unlike impedances of IEN has now been provided with a new direct-digital synthesis generator, having multiple outputs, isolation among the channels, and high amplitude and frequency stability. Experimental results in the new and old configuration are shown and compared.
