As a PC enthusiast, love seeing the NB eLoop there! Until the Noctua A12X25 came out, the eLoop and Nidec GT were top dog. I don't really know electronics, but enjoy these teardowns.
@@pauldenisowski I am a pcb designer myself but mostly for an academic research group and I always wondered how many people work on projects this bit and polishes. It's really impressive.
You‘re absolutely right about the fan noise. If you have ever been the last person in the lab and switch off all the gear in the evening and everything is quiet, you notice how loud some test equipment is.
You've trained me .... I can't call something "A thing of beauty!" without following with ... "A joy forever!" I'm going to have to launch a class-action suit :-)
i got to build the PCBA, safety, performance and calibration testers for the production line for these units. some my job is building PCBA testing fixtures and platforms. and let me tell u, these where the biggest challenge jet to build. the amount of testing and level of performance of every detail is amazing. like all USB outs get a over-current event, the trigger time and recovery time are both tested and log'd. and ges who has a few of these pre-production models just floating around different work spaces. we do.
yeah the 3000 series has loads of issues, like frontends dying randomly, knobs falling off, that kind of thing. My uni had to send all 10 of them we have in the lab back to get the fixes installed.
The most action is happening in the software, like VHDL and also in the ASIC. So not so an impressive schematics I suppose. Old skool top line Tek scopes scopes would have much larger schematics.
Dave, thanks for the tear down. Wouldn’t dare attempt with the MXO4 on my bench. Not enough can be said about the fan and lack of noise from this scope. It really is a thing of beauty.
12:06 These 6 identical Micron memory chips (D9WFH) could form a single 12-bit word memory array for samplings storage. 20:22 There's another Micron 8Gb DRAM chip (D9TBK) near by which could be dedicated for MSO sampling. This is my guess. )
Those are (probably x8) DDR4 memory chips. 48bit memory bus, each transfer operation taking 4 cycles, 48 bytes total (32×12bit samples) per transfer. Extra single DRAM chip - probably RAM for ARM cores
D9WFH is for the MT40A512M16LY-075:E which has a 512M16 configuration (4 pieces -> 64bit) Who knows how they arranged the memory ... could be 12bits for the sample with 4bits input state -> 16bits x 4 channels -> 64bits We can only have a pure guess at it. But the max memory depth of the scope is 400Mpoints and those 4 memory chips are 512M16x4 which is certainly enough.
Ah 😀so there *are still* companies making quality designed and well-put-together pieces of equipment. Albeit in the somewhat high price-segment 😅 Beautiful instrument to see the internals and construction of, my compliments to the design-team of the R&S MXO4 🥇. And thank you for the cool video Dave ! 🌠
@@pauldenisowski Paul, from one engineer to another. One of the many things that sets R&S apart from lots of others is your companies true desire to be a part of the maker and hobby community. Even though a fraction of a percent of us can even begin to afford your kit, you still are in the trenches and seeing what we all think. As you are very keenly aware, that the makers and hobbyists have technical day jobs and a portion of us use high end kit at work and/or have influence on the kit that our companies invest in. Its smart from a marketing and business POV, but it always seems far more genuine than business. It always seems driven by engineers and technicians, for engineers and technicians. I think that is what makes your company really special. Siglent seems to also do this and it always seemed that's the way HP was run.

"Dave nuts over an oscilloscope for 27 minutes" Wait holy shit they have a noiseblocker eloop fan? I had two of those on my PC, those are seriously expensive fans!!
At 13:43, ch 4 (from the left), does the pcb have leftover flux from some rework? I wasn't going to be too picky, but since you talked about contaminents on the pcb.. Don't get me wrong, the board layout is extremely beautiful.
@@tommihommi1 yeah, its already been 8 years ? it seem like it was last 2 years . I'm still rocking a 14nm desktop here , wait, that thing survived for 6 years already ? wow.
At 25:14, it's bothering me that the two differential pairs coming out of the DAC are different lengths before they go to the output amps. They could have placed the DAC in the middle of the two.
21:22 That might be why there are 6 memory chips, to store 12 bits, you divide the address space in 2 and store 12 bits in 6 chips. But I still think they're storing 12 bits in 4 chips by dividing the address space in 3, and the other two are double-parity, You don't want the data getting corrupted do you ? or one of them is parity and the other is ASIC configuration RAM.
Do the outlines that allow for rf cans provide rf shielding by themselves? With the tiny smd components being close to the pcb, they are almost in a box without a lid.
Romanian electronics engineer here! Thanks Dave for pointing it out! I will research exactly where (at what plant in Romania) was made and make it public!
Beauty.😍 I haven't seen the main review and was trying to do the BOM price in my head, but in all the excitment I kindo lost track of myself... Please can you do an update on the PSU, and what they're doing to that ground plane (I'm a little surprised they airn't using a cleaner internal one). If they're taking it straight from the wall they might as well pour vomit on the thing. As for the DRAM it looks as though they're them for input buffers and RAM, with some switching to cope with the bandwidth (RAID0). It would be interesting to know how they're storing the input data, I'm guessing storing 2 values in a single 3-byte pointer (that would help with bandwidth), otherwise they would be wasting a lot of nibbles (Gen-Z probably wondering wtf is a nibble?😅). Little surprised the DRAM doesn't get a little privacy with its own can as a lot of laptops sheild the DRAM, amd ECC is probably a luxury at such speeds. Also, I've never sceen those fans before. Noise Blocker is a fairly well known brand and PC enthusiates will pay a pretty penny for decent fans. I have 6x140mm cooling my CPU as I like silence (German too!)
Maybe the extra 'scope' for shielding (I'm here all week) is future-proofing for the line? They must be planning on using the same board for even higher bandwidths.
Hi Dave, Long time viewer. I really like your content. I observed that on your two videos for the R&S MX04 Oscilloscope it was two different serial numbers. Was the one on your first video a press sample(SN 200176-Cr) to be returned to R&S and the one on this second video is yours to keep/teardown(SN 200183-Bm - Show Room white tag on top)? Thanks!
Pornographic nuthin', that board is Playmate of the Year material! Just plain gorgeous. I gotta say though I was pretty surprised at the price tag. I was expecting more like $20k than $7-8k. Of course I'm sure those options will jam the price right through the ceiling but still, that level of capability for a price like that is a damn good deal.
Hi Dave, really great video, thank's for that. I have oportunity to buy R&S MX04 in base version with 200MHz (wo options) for EUR 4800, is that good deal and do you think that "patching" options in the future woulb be somehow possible ?
The MXO 4 has at least 4 GB for temporary information storage for operating system and instrument firmware and >= 7 GB for waveform data and measurement data. Such information can be found in the "R&S®MXO 4 Series Oscilloscope Instrument Security Procedures"
The OnlyFans comment made me actually giggle. Also, Noiseblocker. That's a name I haven't heard in a long time. Besides, kinda surprised to see a NB fan in an OEM product like that. Usually you have your Delta fans for that
The reason there are six ddr chips is because the adc's acquire width is 12bit,usually ddr chips used four chip in a group, It's corresponds to a 8bit adc.
Also interesting to see that the parts they use also cost thousands of dollars a piece. But then again, they are not paying the retail price, but still.
You know how the razor / razorblade game goes for the "options" for these scopes. And how with the Siglent and Hantek and Rigol - we got the hacks. The cost of this option stack = a nice new car. Hack? I know. Anyone that's buying even the base model of this series wouldn't dare mess around.
Question out of left field, is there a reason pcb traces cannot be made out of different materials that act the same as ic's, caps, transistors, inductors etc, so you don't actually need to put anything on top of the pcb?
PCB traces ARE resistors, inductors and capacitors. But usually only at higher frequencies. Look up "Distributed element filters". You can't do semiconductors like diodes and transistors with PCB traces.
I've certainly seen hybrid modules with resistors silk-screened directly onto the substrate. And of course in the microwave and millimeter wave spectrum, inductors and capacitors are often made with specially shaped pcb traces. As for active devices, I think what you just described is an IC
You can make resistors and caps out of PCB traces, and certainly high-frequency antennas. But transistors require doping tiny regions in certain ways with high precision. You get thousands or millions of transistors or ICs on an 8" or 14" radius wafer, but if you built a large PCB at that resolution, and only placed a few ICs on it, it would cost thousands or millions, rather than the cost being amortised over thousands of ICs
That 12V is similar to how Intel wants it for the new ATX12V standard. Under that standard, the PSU only has to concern itself with 12V, it's up to the motherboard to provide all other power rails that a computer requires (5V, 3.3V, etc...). Which would make PSUs for computers much simpler.
Most of them look like tented vias yes, especially since some traces run to and terminate at them, and others have copper clearance around them (obviously the via is not connected to the same net that the copper fill is, and they wanted to avoid the extra cost and complexity of a blind/buried via where possible).
@@sabamacx When slowly rotating dials, for example, I want to zoom in on the vertical scale, but sometimes it zooms out-probably an encoder de-bouncing issue. Unable to enter the built-in demo mode, can't see any waveform there. And I can't get out unless I press the auto-set button. The LCD brightness behaves wired. It changes to the default percentage (I don't know what's that) while the value in the menu is unchanged. Sometimes this happens after a reboot, and sometimes it just drops after powering on the device for a while. The device will freeze after powering on for long periods (a few hours?) No response for the touch screen, dials, buttons, mouse or even the power button. I must disconnect the power cord or switch off the main physical switch next to the fuse to restart it.
ADC chip alone is worth more than my entire scope.

@@sabamacx When slowly rotating dials, for example, I want to zoom in on the vertical scale, but sometimes it zooms out-probably an encoder de-bouncing issue.
Unable to enter the built-in demo mode, can't see any waveform there. And I can't get out unless I press the auto-set button.
The LCD brightness behaves wired. It changes to the default percentage (I don't know what's that) while the value in the menu is unchanged. Sometimes this happens after a reboot, and sometimes it just drops after powering on the device for a while.
The device will freeze after powering on for long periods (a few hours?) No response for the touch screen, dials, buttons, mouse or even the power button. I must disconnect the power cord or switch off the main physical switch next to the fuse to restart it.
Try to download the new firmware which was release around march 2023.
@@tristentan It is running the latest firmware since I got the scope.
I'm sorry to say but the most beautiful osciloscope "teardown" was the Tektronix Mr. Carlson's Lab showed.
I won't argue.
