A very low frequency ac-dc transfer standard

A low frequency ac-dc transfer standard has been developed to satisfy the NML demand for very low frequency ac-dc transfer calibrations. Tests performed using digitally synthesized signals and synchronised dc measurements showed less than 13 parts per million variation in the ac-dc difference of the standard within the frequency range 0.01 to 100 Hz. >
