I'm looking at one of the Picoscope 2200 series as a hobby 'scope but am confused by the references to the amount of data that the scopes can store.
If I've understood correctly, there are two approaches: to stream the 'raw' data in real time directly to the PC for storage. The data can be acquired at a rate between "1 and 9.6MS/s". The second is to use the on-board storage. Depending on model this ranges from "8kS to 48kS". There is also the waveform buffer which can store up to "10,000 waveforms." So far, so good.
The starting point for what I don't understand is what is the the "S" in kS/s and MS/s? Is it a single data point, i.e. one data point reading at one instant in time? In which case, even 48kS isn't going to last the blink of an eye. And how big (i.e. over how long a period) is one 'waveform'?
To put it in practical terms, say I wanted to capture say 5 seconds of a trace from an output of an Arduino board, how much storage is that going to take up in the above terms? Is it within the capacities?
Basically I'd be grateful for a primer on the scope storage.
