Is it worth buying a Tektronix 7834 (vs. a UNI-T UPO1204) ?

<< < (3/3)

coromonadalix:
for the given uni-t prices  i would go on siglent sds1000x series plus bw hacks and new probes to fit the updated bw

Dannyx:
Thanks for the info. The gist of it seems to be the Tektronix is a poor choice in my particular case - not that it's a bad tool in itself, but not suitable for my use case. That's for tech buffs who know their stuff. It'd be like buying a classic car as my ONLY daily-driver car - bad idea.

like a $70-100 handheld scope

Are those any good and worth my time ? I wouldn't mind spending a "considerable" amount upfront to get an instrument that's still relevant after many years, instead of buying several cheaper gadgets over time because they proved insufficient in the long run, which would eventually only add up to the price of the "proper" one. As an added issue, I'd then be stuck with all this obsolete gear I'd have a hard time selling because nobody would buy it...

I would not recomend to buy these cheap toy scopes. Usually this makes your life painful. And you spend more time to understand the drawbacks of the instrument than learn about to work with an oscilloscope. As tv84 already stated, buy something like the cheaper Siglents. They are more expensive but you even can use these scopes when you are already an expert.

I had much success with a cheap 120€ tiny digital scope and an old analog one. But i did not repair that much. For example: i found a malfunctioning positioning sensor of a car with a DSO nano.

Those better scopes would only make sense, if you would look for EMI problems, are designing some switching circuit ,some filters or similiar stuff.

I wouldn't say that, because a small portable scope and a benchtop scope are not the same thing and have different advantages.
You can buy a bike first and later a car and continue to use the bike where it has advantages.
I don't see a problem there at all.
