HI,
sorry but my English is not good.
I'm acquiring data from serial port, but my available data have just the amplitude (Y-axis).
I know the delta t is 2 miliseconds.
How to arbitrate de delta t to a Chart?
Can anyone help me?

Which property should I set?

Can I do something similar to calculate the power spectrum?
05-10-2011 12:04 PM
Because my input signal is 500 Hz and the power spectrum is not showing the right value!

why not use "build waveform"?
since you'd have the array of data, and knowing the dt, one could just re-build the signal?
and for the FFT i usually use the express FFT...

If you:
Then you can wire the output directly to a Waveform Graph and the delta frequency and frequency range will be automatically correct!!

I don't use "build waveform" because I acquire the data one point at a time.
