Digital Scope Specs: wfms/s vs. GSa/s vs. Mpts/s vs. bandwidth? Answered
Question say's it all. I understand the concept of analog bandwidth, being that the signal amplitude will be attenuated about 70% at the rated frequency, or something along those lines. I also think I understand the concept of sampling rate, being that the ADC inside the digital scope samples the input voltage level periodically (possibly billions of times per second), and then this gets stored in memory, and displayed.
However, then what does the "Mpts/s" figure mean? Is this telling me how many points of the signal can be stored in the memory to be plotted on the screen? how much of this is 'good' and 'good enough'? Also, what about Waveform Capture Rate (wfms/s) I really have no idea for what might be, How it 'waveform' defined? a single period of a repetitive signal, like a ramp wave or triangular wave? Perhaps also a arbitrary wave? What would this tell me? Again, how much of this is 'good' and 'good enough'?
