Oversampling, particularly pronounced in the long-memory models, can be used to increase the displayed trace's effective resolution: the ability of the instrument to distinguish closely spaced voltage levels. This is done by filtering the digitized signal using Enhanced Resolution, available in the optional WP02 Advanced Math Package. Although similar to signal smoothing using a simple moving- average filter, enhanced resolution filtering is more efficient both in terms of bandwidth and the superior passband characteristics that result. And on waveforms with single-shot characteristics, it can be used instead of successive trace averaging. $GYDQWDJHV Enhanced resolution filtering improves two important characteristics of the oscilloscope. Resolution is improved by a fixed amount for each filter. This true increase in resolution occurs whether or not the signal is noisy, or whether a single-shot or repetitive signal. Signal
