Title: ET310A Handheld 10MHz 50MS/s Oscilloscope & True RMS Multimeter
Post by: pascal_sweden on May 06, 2015, 10:56:14 pm
Is there anybody here who has used this handheld scope? Is it usable? What are your findings?

The first thing I noticed when I saw this is that it doesn't have a BNC connector and no probe. So to use it with a scope probe you need an adapter. 10MHz? Not with any fidelity without a proper input. I would avoid it.

Get a second hand tek scope meter or a pocket sized hps140. If you just want to do quick checks.

DC accuracy is specified as 0.75% +- 10 counts. With only 4000 counts full scale, this amounts to +/- 1% with a full scale reading and +/- 3.25% with a 0.1 of full scale reading (i.e. lowest reading before switching to next lower range). That is awful. The accuracy for other functions is even worse. Granted, it might be more accurate than specified, but that is a $150 risk.

You can also measure a c64 with a hantek 6022be? That's only a 60,- risk? And it's 20 MHz ?

Maybe you can turn this unit in a Gameboy Advance :)
