@@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.

@EEVblog 11 місяців тому

@volodumurkalunyak4651 11 місяців тому

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

@ppdan 11 місяців тому

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.

@garethevans9789 11 місяців тому

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!)

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.

@EEVblog 11 місяців тому

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.

@danmenes3143 11 місяців тому

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

@TomLeg 11 місяців тому

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
