I'm trying to measure rise times using 3206 from 5V digital signals.
The best rise time (10% to 90%) i get is about 35ns. My problem is that i'm measuring devices that should perform at about 10ns.
Is this a limitation of 3206?
Theoretically an analog oscilloscope should have about 0.35/BW, which would be 1.75ns for the 3206, wouldn't it? And a digital oscilloscope is supposed to perform better here....
Please give me a solution.
My goal is to check if a signal has lower rise time than 18ns... how can i measure that?
Thanks very much
