DC voltage up to ±10 V
Typical calibration accuracy (direct comparison to a second Josephson voltage standard)
±1 nV @10 V
ΔV/V10V=1×10-10
Typical calibration accuracy of DC voltage standards, e.g. Fluke 732B (limited by the noise of the DC voltage standard)
±100 nV @ 10 V
ΔV/V10V = 1×10-8
AC voltage up to 1 kHz frequencies
Typical calibration accuracy (direct comparison of two 4-sample Josephson waveforms)
±200 nV @ 20 VPP, 1 kHz
ΔV/V = 2×10-8
Typical calibration accuracy of calibrators, e.g.
Fluke 5720A (limited by the noise of the calibrator)
ΔV/V = 5×10-7 @ V ≤ 7.1 V(rms), f ≤ 1 kHz, 1 min measuring time
