Dear all hello,
I was using my oscilloscope, measuring the output of a power supply (switch mode), and since I am not familiar with oscilloscope measurements yet, I was changing the volts (vertical section) from 5V to 20V when the input was 9V.
The result was changing completely and for example the scope showed me in these two measurements different results.
At 5V /division it showed me a Vp-p (probably noise I am not sure of what it is) of 600mV, but at 20V/division a 2,4V Vp-p showed up.
The same happens with a 9V battery, and every measurement.
So when I make a measurement the where I should put the V/division? very near to what I measure? Propably I am missing something here.
Thank you very much for your help
