Sample Rate
The maximum sample rate of the T3DSO2000 is 2GSa/s. The actual sample rate of
the oscilloscope is determined by the horizontal scale and acquisition depth. Turn
the Horizontal Scale Knob to adjust the sample rate.
The current sample rate is displayed in the information area at the upper-right corner of
the screen.
The influence on the waveform when the sample rate is too low:
1. Waveform Distortion: when the sample rate is too low, some waveform details are
lost and the waveform displayed is rather different from the actual signal.
2. Waveform Aliasing: when the sample rate is lower than twice the actual signal
frequency (Nyquist Frequency), the frequency of the waveform rebuilt from the sample
data is lower than the actual signal frequency. The most common aliasing the jitter on
fast edges.
3. Waveform Leakage: when the sample rate is too low, the waveform rebuilt from the
sample data does not reflect all the actual signal information.
