| Zusammenfassung | Pulse-driven Josephson junction arrays are quantum based voltage sources that can generate arbitrary waveforms with exceptional accuracy. However, wiring this perfect voltage sourcetoadeviceundertestdrasticallydecreasethesestateofthe art performances and causes deviations which scale quadratically with frequency and cable length. A load compensation bridge will be described in this paper that fully compensates the load of the Josephson arrays which is caused by the input impedance of the device under test. With this setup the frequency dependence up to a frequency of 80 kHz can be suppressed with an overall uncertainty of 2.8 μV/V. |
