• Aliasing
When the sampling rate is comparatively low with respect to the input signal frequency, the
harmonics contained in the signal are lost. In this case, some of the harmonics will appear at
low frequencies due to the effects described by the Nyquist sampling theorem. This
phenomenon is called aliasing.

• Retrieval of waveform display data
The WT3000 retrieves waveform display data to the memory at a sampling rate of
approximately 200 kS/s. The frequency that allows displaying of waveforms that are close to
the input signal is up to approximately 10 kHz.
