Hi,
I have a measurement of voltages(time). I measured a voltage signal of 10-29,9 kHz generated by an AWG on my scope. When I take this data into origin and do a FFT. I get frequencies between -1,16e-8 and +1,16e-8 with "Frequency [1/6]".

- What does "Frequency [1/6]" mean?
- I expected my frequency range given above but the calculated frequencies are far away from the reality. Since there is no noise generator in between. I should get what I put in.
