You can not really measure reliably 400Mhz with a 70Mhz scope, so the peaks you are seeing must be way below the -3 dB point on a 70 Mhz bandwidth, and you may not see all the harmonics either, unless I am missing something?
Sorry to bother you . I have a quick question: on channel 1 what kind of antenna did you plug in? is this just a regular antenna with BNC or something special ? thanks. Andre
Hi just a silly question, sample rate is max 8gs/s, can the FFT span go up to 4GHz or is it software limited to 500 MHz? Yes at 4GHz it probably useless... but at maybe at 800 or 1.2 GHz (whit 460MHz BW) you can still do some Harmonic measurement/see if there is a signal?
You can comfortably resolve 1.9 GHz peaks with this scope FFT with a 200 kHz RBW. Search "RIGOL MSO5000 a 1.9GHz?" on youtube for an example (at 9:36 on that video)
Because "350Mhz Oscilloscope" means that the -3dB point is (approximately) at 350MHz. Higher frequencies are shown as well, but will be attenuated. The sampling rate of this scope is so much higher than (double of) these 350MHz, that there is also no issue with the Nyquist theorem.
Really nice. I just ordered myself a MSO5074 and will try out this as well when it arrives. Thanks for the video. Greetings from Thor in Norway.

@@OndrejPopp it is hackable to
@@anthon5504 Ok tx!
You can doom on it.

It’s just a normal BNC Antenna for Amateure Radios
Thanks

Works over 500mhz, have not tested it over 1Ghz though

Hmm, why you can measure with a max. 350Mhz Osiloscope frequencies above 400Mhz?
Because "350Mhz Oscilloscope" means that the -3dB point is (approximately) at 350MHz. Higher frequencies are shown as well, but will be attenuated. The sampling rate of this scope is so much higher than (double of) these 350MHz, that there is also no issue with the Nyquist theorem.
@@Gaston12345 Thank you very much! :)
Hi, it seems that you chanced the FFT color to White.
How did you do that? Default is Purple.

Camera was not that great, it's purple
Ok, thanks
Nice show. Thanks.
