Evaluation of low-frequency characteristic of a thermal converter using a programmable josephson voltage standard

A new dual-heater thermal voltage converter (DH- TVC) with improved low-frequency performance has been developed at the AIST. Frequency characteristic of the DH-TVC was evaluated using a dual-output programmable Josephson voltage standard(DO-PJVS), and was confirmed to have low-frequency flatness better than 10

down to 1 Hz.
