Abstract : The patent relates to an oscillator which provides an (f sub 1)(V sub 1) analog signal to a summing amplifier. The same oscillator signal is conducted through a frequency multiplier and voltage attenuator to produce an (f sub 2(V sub 2) signal also applied to the summing amplifier. The amplifier output is converted to digital signal samples by the analog to digital (A/D) converter to be tested and a computer counts the number of (f sub 2) samples in an (f sub 1) sample. By comparing received (f sub 2) samples with the expected (f sub 2) samples, resolution is determined.
