tautech, could you do me one more favor? Would you please run the first 5 second test again and after it stops, change the secs/div to 10 usecs? I want to see if the sine wave looks as good as the 5th screen shot when it does a 5 second capture. Looking at the 1st screen shot it appears that the wave will still be clean.
Sorry, I should have mentioned that in the beginning. If the scope will capture 5 seconds @ 60 kHz and I can then change secs/div and see the individual sine waves, I will be ordering the scope tomorrow.
Thank you.
It won't be, period. Captures fix the available sample points to that moment in time.
The 5th image was a free running trace so the samples are continually overlaid on the display whereas a Stopped and magnified capture has far lesser data points, only those at time of capture.
The 4 first images are from Roll mode then Stopped and magnified and dedicated Roll mode offers way less mem depth in which as the magnified trace shows a limit to the magnification.
I didn't explore the limits to magnification in auto Roll mode however with far more memory available I suspect you can go all the way to their
fastest setting, 500ps/div. Nope, 500ns see below.
I'll check but not for a bit as it's dinner time here so gimme an hour or 2.
Anyways, all this certainly demonstrates the advantages of a deep memory DSO.
