• Aliasing
When the sample rate is low compared to the frequency of the input signal, the high
frequency components of the signal are lost. In accordance with the Nyquist sampling
theorem, the high frequency components in the signal are misread as low frequency
components. This is called aliasing.

• Sampling of waveform display data
The WT500 samples waveform display data and stores it to memory at a rate of
approximately 100 kS/s. The WT500 can accurately display the waveforms of signals with
frequencies up to approximately 5 kHz.
