I tried that for month last year. Tektronix will reach more than a hundred easily. I just can't find a scope that I can trust that it works and that fits the price.
That's why I asked for those small scopes, if they increased in usability.
You mean those 100kHz kit "scopes" and the cheap versions of DSO Nano? Nope, they didn't. For 60 bucks you can't expect a usable scope unless you buy a used analog one. Also for 60 bucks or so you need to accept that you may not be able to have a 100% as-new working instrument. It will be used and may have some warts that you will need to fix. That's normal - you are shopping in the bargain basement here!
FYI, there are other brands than Tektronix. Old Tek scopes are being sold for ridiculous prices, often more than a brand new and orders of magnitude more capable digital scope from Rigol or Siglent costs. It is kinda like with Apple products - you often pay more for the brand, logo and nostalgia value than the actual product ... Forget Tektronix. Dave did some videos on how to find a bargain scope on eBay in the past, check those out - he lists also brands to look for, e.g. Phillips/Fluke, Kikusui, Hameg, HP ...
Also, if you don't have more than 60 euro, then don't eat out for a month and you can easily save another 60 to be able to afford e.g. that Picoscope. Or a decent analog scope. Jeeze, dude, you are in Germany, what should people in places like India or some South America countries say?
