A low frequency Josephson impedance bridge

• We describe a low frequency Josephson impedance bridge and the measurement methods. The bridge is useable below 400 Hz and is based on two programmable Josephson voltage standards. Measurements of 1:1, 1:2 and 1:10 capacitance ratio have been performed and compared with ratio measurements of an inductive voltage divider bridge. © 2016 IEEE.
