UNI-T MSO2304X Complete Teardown - Inside UNI-T's 300 MHz Mixed Signal Oscilloscope

[@_S13_]

I appreciate these teardowns of scopes. Low to mid-end is where most hobbyists will be purchasing their equipment, and getting a basic understanding of what quality and architecture you are buying is very valuable! The architecture alone can reveal so much about the strengths and weaknesses of a device. So keep the teardowns coming!

Just as a correction, that Kintex 7 FPGA is actually around $100 in single quantity from LCSC (a reputable Chinese electronics supplier equivalent to Digikey/Mouser). The price for UNI-T is likely lower than that $100 as they may be buying direct from Xilinx and in larger than single quantities.

Huge thanks! This has been so far our best 2025 tech thriller. Or as Dave would say: Contains endless Bobby Dazzelers!

[@seancurry2863]

Thanks Kerry, interesting teardown, especially the chip prices!

[@AndrewJones-tj6et]

Great teardown Kerry. A lot of effort was put into that design.

[@wtmayhew]

Thank you Kerry for the teardown tour. I am amazed at how much capability is packed into a test instrument that is not inexpensive, but within reach of an average person. The equipment I used when I started working is absolutely primitive compared to this MSO. It is tough to believe this MSO can be sold at this price given the cost of the components alone. Even Uni-T probably procures these parts in thousands quantity, which makes the parts still pretty expensive.

The FPGA at 4:05 alone costs $1000 and the complete scope costs over $2000 + tax. That is not within reach of the average person.

@@simontay4851 If you need the kind of analytical power of the oscilloscope shown in this video as a tool in a small business, it would be certainly be within reach. That is what I mean by ‘average.’ I’ve seen car enthusiasts drop way more money than the cost of this oscilloscope on outfitting drift cars. This Uni-T oscilloscope is too much tool for the job for a beginning electronics hobbyist. A more affordable option would be something like one of the Digilent Analog Discovery 3 which starts at $379 US (Amazon) snd possibly less with educational pricing. The Digilent also provides MSO capability and can decode even more protocols than this Uni-T oscilloscope. The Digilent requires an accompanying PC.

Note that the main ADC footprints have higher number of pads than pins on the actual ADCs. 4 more on each side. Could this this be reserved for the more powerful ADCs used on 3000 series?

[@stevetodd7383]

I’m a little confused as to why they need a Spartan 6 along side the Kintex 7 FPGA. The Kintex dwarfs the Spartan in terms of its capabilities, so unless they have run out of IO pins (and the base 325T model has 400) then the Kintex has literally 20 time more of everything.

UNT-T did a good job.

[@stephenwhite506]

The high price of the FPGA you are quoting includes the development software as this FPGA is not supported by the free version of Vivado.

[@MrMaguuuuuuuuu]

They have 30day free evaluation licenses. Just keep renewing 😉

[@onurates9311]

love it !!! Thank you 🙂

[@Techeletrônica-2024]

Very Good - 😊

[@MrMaguuuuuuuuu]

Maybe you can generate a BOM, schematics and layout for purchase. I’m sure there’s a market for this information. 😉

It's fft is significant faster than rigol，which is soft implemented

[@ChipGuy]

Nice teardown, really well done. I already don't like the soldered in battery and in fact it is forbidden in the EU since 2024 to do that according to EU directive 2023/1542 Article 11. So Rohde & Schwarz for instance would not have any problems to take legal action and get EU customs to prevent these from entering the EU. I am curious if something is going to happen there or nobody is going to take action.

[@stephanbode548]

Thanks! What makes me thinking is the capability of the ADC's: only 1GB/s 8 Bit. There are 12Bit ADC's from TI/Analog Devices. The used ADC is form 2019. ... Uni-T only has 8 Bit Osci's. So not comparable to Siglent, Rohde etc. The Fan is a pitty. Sorry Uni-T this is crazy.

[@thegame4027]

The real price they pay for like FPGA is likely 350-450 USD. We purchase a similar intel FPGA with MSRP above 2200$ for 400$@1000pcs. Lowest we ever payed before covid was 290$.

[@douro20]

I see a few chips with legacy logos...the one which stands out the most is the Kintex-7 FPGA which still says Xilinx on it. They must have acquired a huge batch of NOS chips.

[@MrMaguuuuuuuuu]

Do a video on prices in China for these components vs US or EU. Curious how badly we westerners are getting screwed by these chip companies.
