Those cheap 1GSa/sec 100MHz Chinese scopes are fine for HF radios. I designed my SDR using one. Maybe get some better probes than what it'll come with.
Just stay away from USB scopes which all seem to exaggerate their bandwidth by a factor of 4 or 5. 73 David AE9RB On Thu, Jul 31, 2014 at 2:20 PM, Sova <[email protected]> wrote: > I’m looking at getting a scope to setup a basic test bench at my place. > Mainly I’ll be using it to repair amateur radios, amplifiers, and maybe > some debugging of digital circuits later. > > > > There is a guy on CL that is offering me an older Tektronix 2252 100Mhz > analog scope with digital storage and integrated volt-meter for $350.
