Abstract :
The pulse-driven ac Josephson voltage standard (ACJVS) system has been operated stably in Korea Research Institute of Standards and Science(KRISS). We have improved the system operation so that the distortion has been reduced compared to our previous report [1]. Since this system can generate arbitrary waveform with quantum-mechanically precise voltages, it can be applied to precision ac electrical measurements. We will present single-tone waveform synthesis results at different amplitudes and frequencies for ac metrology purpose, and will describe our preliminary result on ac-dc difference measurement using ACJVS and a commercial thermal transfer standard.
