Yes indeed. All those are available cheaply at hamfests ;)

if you are a beginner what oscilloscope you'll buy ?  conditions :

- for hobby (ham utility)
- enough monney (1000 pounds)
- new/used
-or maybe a spectrum analyzer

 thanks

Every few days someone comes and asks “I’m a beginner. Which scope should I get?”

It’s been discussed a thousand times. We don’t need to answer it again, and you could already have your answer if you simply went and searched.

Replying with annoyance and 3-word answers isn’t going to make people help you, it’s just going to piss them off.

For anyone wondering .... that is a joke.  Literally.  Have a laugh and think nothing more of it.


For a serious answer to the OP, this is the best I have seen here:

Sorry, that's absolute nonsense.

If he is going to play with DIY kit on HF, any old 20-50MHz scope would be plenty already - most likely the first attempts would be some crystal driven radios for 80 or 40 meters or some BitX kit anyway. A 100MHz Rigol is a luxury for many hams I know. Spectrum analyzers even more so, given the prices. Very few hams have one (or can afford one). And people get by just fine.

You may just have to improvise a little, for example using that FFT in Matlab/Python. Or use an SDR radio ($20 dongle) and some free software with a nice waterfall display to check for splatter (or, more likely you will be told rather quickly on band if your signal isn't clean!). Which is pretty much all most hams would need a spectrum analyzer for - the remaining ones that know how to use it for other things also know whether or not they really need it (and can afford it).

He didn't say what exactly he wants to do but beginners are not likely to start homebrewing gear for the 2m band or higher, that requires both some experience and equipment. So why exactly would one need a 500MHz scope for getting started in ham radio?

(btw, even 2m is doable with the 100MHz Rigol - the frontend is usable to some 150MHz, even higher if you can put up with some attenuation. Certainly not ideal, but possible if you just want a quick check of the signal).
