I was looking at oscilloscope specs (it's a bad habit I should learn to break
), and I was trying to figure out how long it would take to fill up the memory of the scope. I've tried doing the math myself, but I'm pretty sure I didn't get math correct, so I'm turning to the community.
Please note, I don't really *need* the answer. I'm just really curious.
If I have a scope that samples at 5GS/s, does 64K wfm/s, and has 80Mpts of memory, how long would it take to fill the memory up?
Thanks
You are missing one important parameter: at what time base?
Timebase defines how long (in time) will be every individual capture.
If we have 10div horizontally, and 100ns/div, every trigger event will initiate a capture of 1µs in length.
At 5GS/s that is 5000 points captured. Per every trigger.
If you have a 1MPTs scope that means you can have 200 such captures in a memory total.
ON a 10MPTs scope you can have 2000 such segments.
If your timebase is longer, there will be more memory used per trigger. So less segments available total.
Up to the point where you use up whole memory for single capture..
But this is one of those questions that are discussing a detail without explaining whole picture.
What is a problem you are trying to solve?
