Resumen
This paper shows that very high precision ratio measurements (uncertainty of 3 parts in 10⁶) can be performed, also at frequencies of 1 kHz, using the multimeter HP 3458A. It is proposed to slightly change known algorithms to control the instrument, and a new uncertainty calculation is presented.
