Stepwise waveform generation using Josephson voltage standards for joule balance

The Flux linkage difference measurement is one of the key techniques in the joule balance with an electromagnet using ferromagnetic material. An arbitrary stepwise compensation waveform is needed to offset the induced voltage of the suspended coil with the finite rise/fall times. In this paper, the transitions of the induced voltage are respectively divided into 12 and 120 steps, and then processed to the PJVS with the purpose of synthesizing the desired transition for the compensation voltage. The result confirms that the PJVS has the capability to generate an arbitrary stepwise compensation voltage to offset the induced voltage.
