New handheld touch DSO, Fnirsi 2C53P, claimed 50MHz/250MSps (April 2024)

[csuhi17]

I played with it a bit, but I couldn't find the 64K memory, compared to the HDS272s, which only has 8k...

"kByte" is not the same unit as "kpts".

Confusing, but at least they named it correctly this time.
Others write 64k, so you can only guess.

I'm a bit confused by this.

Is 1ps not 1 byte for an 8-bit oscilloscope?
So 64kbyte is not equal to 64k samples?

I no longer know for which scope it was written as 128kBit, I knew that it was only necessary to divide by 8 for that type.

You're probably right, I confused it with kBit myself. 
But of course it's still true that it's not the same unit in principle.
You can see that if the scope has more or less than 8bit vertical resolution (or ADC? There is a trap everywhere...)

For the 1013D and 1014D it specs 240Kbit which is not even correct since it uses only 4KByte per channel of which only 3Kbyte is effectively used. So of the available 240Kbit in the original FPGA (The Altera one) only 8192 bits are used for storing the samples.

MTX2088 ADC

This is Dual Channel 8-bit, 100Msps ADC... (analog AD9288)
datasheet

but can't see the processor. Is it hidden under the shield?

MCU is on bottom side, and it is Synwit SWM34SRET6

How did you find the MCU make and model? On csuhi17 his pictures the marks on the chip are removed.

The ADC is most likely the same as used in the 1013D, 1014D and some of the other scopes FNIRSI makes. They can be overclocked but have not tried it myself, because it would require reprogramming the FPGA in the scopes I have. There we assumed it to be the AD9288 or a clone of it, but the markings have been removed, until now in this one where it is still there.

I wonder why they choose the bigger FPGA for this scope, instead of the most likely cheaper ones used in the other scopes.

Yes, the marks was removed but not complete (not deep enough), and still can see the mark.

Roger that     thx.

Looks to be quite a span between the offerings, from around 16 to 60 bucks € (incl. EUVAT) with more or less identical hardware  https://www.aliexpress.com/item/1005006741973129.html?
// perhaps there are hardware differences, as some do claim 100x while others 50x - but these x-magnifying ratings on cheap Chinese gadgets are usually as informative as putting your tongue out the window, in the hope of landing the daily news.
Though, It could be handy, such a small self-contained handheld-magnifying lup, if it doesn't drain its battery too fast while in limbo.
- time will tell.. took the plunge on one as it could also be a gift for my elderly mom, who often have issues reading small text.
