I'm electronics teacher and I'm wondering if it's possible to find some oscilloscope (and why not spectrum analyser) for recommending my students to be able to work at home.
I'm thinking on something near $50-$70. The question is may be something that is not crap for these price?
Two or three years ago I'm sure the answer was no, but nowadays?
I've seen to cheap
It is 200Khz oscilloscope and 75Khz spectrum analyzer... very cheap but in Khz
It aims to be capable of 20Mhz, 2 channel.
What do you think?"
