Fnirsi -TC3
spanakop:
Whilst looking for a component tester, and I really couldn't be arsed to look through 342 pages of the form post, I came across this

Fnirsi has released a new version of the their combi tool. It has a component tester, Oscilloscope and Signal generator all on the same package for around £40 including a 10x probe.
I'm interested in the component tester side of things rather than the Oscilloscope tbh. I see the other additions as a bonus feature.
has anyone had a play with this? They state the specs of the oscilloscope are upgraded from their last one.

There's a few reviews on youtube:

If you do not need the oscilloscope function, why spend such a large sum for it.
Fnirsi sell a component tester alone. It has a fake chip on it marked Atmel328, but it is not even a clone, it is a completely different chip, so you can not as of yet customise the firmware. However it is a reasonably accurate device, or mine is. https://www.aliexpress.com/item/32795518755.html
Plenty of others out there as well.

I bought the TC3 expecting it to be a toy, that was maybe better than the TC1. It's a toy compared to a real bench scope, but the thing actually works.
I used it today to test caps for the outside foil, and it actually worked. Results consistent with the SDS2504XP.
The biggest downside of trying to use this as a scope + AWG (besides the obvious) is that the AWG only functions as a square wave generator (typical for probe compensation) when the DSO is active. You can't use it to send a sinewave to the DSO.

I have a TC3 as well. I think it strikes a good balance between the $7 component testers and the $50-$100 pocket scopes. Of course I'm not using it for serious bench measurements or signal generation, but as a portable tool for simple field work that I'm not going to lose much sleep over if it gets lost or destroyed, it's great.
