Ahhh... got it. I thought you wrote 'is' instead of 'if'. ;)
Wim13:
See pictures, ALIAS OFF on FFT, it is totaly useless
The picture with alias ON, that is how it looks on a spectrum analyser...
also added 3 kc picture, you can see that the other spikes are below the
level , as on alias off. Thats why they are not visible on alias off
For comparision, added a 3kc from an analog signal generatior
Wim13:
@ Teneyes, dont use rectangle, use a window, as Hanning or Blackman

@Wim Thanks Wim , that is Wonderful

Better FFT of 3KHZ
and 3K with FM modulated with 50 Hz
Hoping Rigol changes FW so Center frequency stays at Center, for Aliasing Also
