Tablet DSO <= $500 for the recording of sub ms duration DC voltage spike events

Silver_Is_Money:
So for clarity, even the budget Hanek TO1112 tablet DSO that goes for about $189 would suffice here?

Yes.

I did a couple of quick tests so you can roughly see what the signal might look like in your case in specific cases.
Two images were taken with the Owon HDS272S, which has a memory of 8K, sampling 250MSa, but reduced it to 5MSa due to low memory.

The other is a Micsig TO1104 with 28M memory and 1GSa sampling.

I take a few pictures with Micsig, the name of the picture shows how much sampling and how much memory it was made with.
I made them all with 100us.

If the pictures are not clear, ask, I'll try to explain.

The FNIRSI 1013D digital tablet is on sale for $120 US.  Do you think it would suffice in this application?  Here are the specs:

The specs of the FNIRSI-1013D are a big lie. The original Altera FPGA has 270Kbits of available embedded memory and the newer ones with Anlogic FPGA's have more. (496Kbits or 700Kbits) But what counts is how many of these bits they used, and that is only 32768 bits per channel. So 4KByte per channel of which only about 3500 bytes are usable.

The sampling rate is only max 200MSa/s per channel instead of the 1GSa/s marking on the front and the bandwidth is 30MHz at best.

No. Fnirsi should be forgotten, because either they lie and do not provide the performance they claim, or they do not know what you want.

As far as I know, it is not possible to save the results only as an image, you cannot later load them into an Excel table.

I couldn't find anything better than the Hantek TO1112 in this price category.

IF I didn't have the two Owon HDS, I would have bought the Hantek TO1112 instead.

But I wouldn't buy the 1GSa/s version from the Hantek TO1000 series, because the Owon TAO series offers more and is only a little more expensive.

In other words, it's not worth it.
Under $200, I think the HANTEK TO1112 is the winner.
You don't need C, D edition, because if I think correctly, you are not in the electrical business.
