Title: Using a Hacker RF one as an oscilloscope
Post by: daslolo on April 24, 2018, 09:58:59 pm

I don't know if it makes much sense but I saw clean signal from 1 to 6000 Mhz and wondered if anyone was using this cheap gear as oscilloscope and spectrum analyzer.

It has 20 MSPS ADC, so the actual bandwidth of the signal will be pretty low.  You can do a spectrum analyzer, but it is impossible to make an oscilloscope out if it.

And that is not to mention that a scope that can't see blow 1 MHz is sort of useless.

That's right, now I see why it's no good for oscillo. Weird that Ossmann said in 2014 that it's doable...

even if you can tolerate > 1MHz signal, i suspect there is no phase information for the displayed FFT from HackRF, (RSSI or magnitude info only), meaning if you want to generate time domain signal through inverse FFT, then you have to guess the spectrals' phases, so the t-domain shape can be anything.
