Hello all! I'm grzegorz (you can call me greg) and i'm electronic hobbyist.
Some time ago i saw video from eevblog channel:
Dave was talking that rigol 1054z have terrible fft function.
Because I brought that 1054z oscilloscope few weeks ago I wanted to test it.
I used signal generator from my phone.
And test results can be seen in attachments.
Now I'm learning about RF signals so I need spectrum analyzer to see if my VCO or other radio circuit work.
Unfortunately i don't have that money to buy extra lab equipment.
But i think that FFT from rigol is good for me. I didn't have super ultra precision but it can do it job in my case
(I only need to know what harmonics, carrier waves and modulation waves are present in waveform)
I think that Dave exaggerated quality of FFT function in rigol 1054z.
Tell me what are you thinking!
