Abstract :
A synthesizer of precision AC waveforms based on a binary SINIS Josephson junction array has been developed. The array segments are individually biased using a high-speed bias source with a 250 ns switching time between voltage steps. The accuracy limitations of the system will be discussed and various measurements between the synthesizer and thermal converters presented
