There are two fundamental problems that may prevent [V.sub.m] from being acceptably close to [V.sub.s] First, the source of the voltage is not an ideal voltage source; second, the voltmeter is not an ideal voltmeter.
Simulations made for a sampling voltmeter showed that the errors in the measured rms amplitude have a non-normal probability distribution, such that the probability of large errors is much greater than would be expected from the usual quantization noise model.
