Hello Everyone ,
this is my first post on this forum. I'm a qwt beginner. I would like to plot some curve in real time , I've seen today the example of oscilocope . Its 60% what I want. I've ran this example and I find out that when the frequency bigger than 20Hz , its difficult to get a "good sine waveform" I've tried to change sample interval and time but waveform is still not good when the frequency bigger than 20Hz .
my question : what schould I do to get a "good waveform " the frequency are for example 1000Hz , 3000Hz?
Any help woulb be appreciated
