Abstract :
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 synthesised signals and synchronised precision dc measurements showed less than 30 ppm change in the ac-dc difference of the standard in the frequency range 0.01-100 Hz.<>
