Dear All
I have plotted waveform graph frequency vs amplitude of real time signal. I am using measurement computing USB1208FS. I used fft.vi to plot the graph and get the waveform which is attached. On X-axis frequency is form 0 to 0.49HZ. But I want to increase that from 50 to 500 hz. When X-axis scale is in auto select mode then it automatically adjust to 0 to 0.499 hz. When I deselect autoselect mode and edit x-axis from 50hz to 500hz then no waveform comes on display. I have set the sapling rate of 1024 and count of 500. Please guide me how can i get the desired waveform graph. The waveform which i plot is shown in attch1 and my desired waveform is shown in attach2. waiting for response
Kind Regards
Urfee
