Aliasing or "digitisation error"

[regmech]

Professor is seeing "clipping" of voltage signal. The actual signal is a much lower frequency than the visible noise. However, I suspect that this "clipping" will disappear if the sample interval is decreased enough. What is the minimum interval of a 6034e?

Greetings,

The PCI-6034E has a 200 kS/s maximum sampling rate. Thus, the minimum sampling interval is 1/200k = 5 us. Below, I have included a link to this device's product page:

NI PCI-6034E

When you refer to clipping, what exactly are you seeing?
