All of the TDS 300 scopes sample at five times their bandwidth, assuring users of accurate real-time acquisition up to the full bandwidth of the scope, even for single-shot events. This is well beyond the theoretical two samples per period necessary for a DSO to acquire a true signal. If a DSO cannot sample at least twice as fast as the highest frequency component, aliasing occurs and the scope displays a waveform with a lower frequency than that of the actual input signal. The TDS 300 Series' high degree of oversampling not only minimizes aliasing, it also provides a higher resolution waveform.
