Abstract
This article examines the non-linearity and gain error of a commercial digitizer on the 100 mV range with a Josephson Arbitrary Waveform Synthesizer (JAWS) as a reference. Different digitizer input filter settings were studied, and the shortest aperture of the digitization window was chosen to maximize the processing speed. The results revealed a maximum non-linearity of 0.09 µV on the 100 mV range, over a 10 mV (rms) spread, at a filter frequency of 1 kHz. A gain stability over 12 hours was determined to be 0.92 µV/V.Proceedings Title
