Bird is a puffin. Black and white with a coloured beak, and not common in Australia outside of a zoo. And fast flying so a fast colour device. 50R termination going to be well cooked if you put more than 2V into it, going to say you will have a call for inputs to have a warning on that mode, or you will be cooking input resistors within a week if you have anything over naff all input power.
@@EEVblog I can see the one accessory being sold will be a 50R inline termination that can handle 5W, probably with 6dB attenuation or more, so that you can actually use the 50R input.

The RK3399's big value proposition is probably that x4 PCI-Express port, which makes for a very convenient way to talk to logic on FPGAs. They might even map the waveform store RAM directly into the SoC's address space.
Thanks for letting us know, the interface between the SoC and FPGA was one of the things I was wondering about, PCIe is a really nice fit for this application indeed!
@@aDaWaN Makes sense, after all a single spin cast mould that integrates it all is going to be cheaper in the assembly line, and you can get great dimensional stability in that single part as well so minimal machining work to get good results. You need a heat sink, so makes sense to have a single part then for the entire range, and it definitely cuts the cost down in assembly. Spin cast, run through a single CNC mill to level the critical paths, and drill the holes and tap them, and be done. One fixturing clamp only needed, and perhaps 3 minutes of machining time total. 400 per machine per day is probably faster than the rest of the production line.

Rockchip 3399 is commonly used for android boards. I think Linux will run on a wide range due to the large community but I always see the rockchip 3399 and the older 3288 on android devices- it’s probably because there is well validated software to run on it. The two buttons populated are recover and reset and I always see them populated regardless of if it’s intended to be worked on. Somehow it must be required. I’m working on a 3288 now trying to hack an old advertising display with touch screen on it. It’s supposed be to be “pretty powerful” for android because it’s also found commonly in Chromebooks
Looked at using a 4053 for a sample+hold circuit once. The worst-case ratio between on-current and off-current wasn’t extreme enough. Ended up making a large spreadsheet, and settled on using a DG444.
excited for hdo1000 with12bit at $999. would be very nice to check for whether it actually has that 50 ohm input not mention in datasheets but stated in ui and the front panel.
@@EEVblog Oddly enough hdo1000 user manual 5.4 says: When the input impedance is set to "50 Ω", the channel coupling is set to DC coupling by force. Am confused.
@@bakagaijin7452 Probably used with external 50R terminator, and software sets the input to DC coupled when you select the 50R termination for the display unit.
an interesting note with the closer look around 24:25. the micron memory there (and likely for the SoC as well) is 4Gb/512MB x16 width DDR3L 1866MT/s memory, so there is 2GB total RAM there, which makes sense with the ongoings under the hood. the 3399 ARM SoC has a PCIe 3.0x4 link which also makes it easier for coms to the FPGA with low latency, as a few people in the comments here have mentioned. this is fitting given it's 2Gs/s would be too much for serial unlike lower sample rate and bandwidth scopes.
Very clean construction; interesting choice to put the R&D into the front end with a bespoke chip and ADC, and shell out for the Artix7. Crazy amount of heat and noise, but I think a lot of people will find the trade-off acceptable! Would be super cool to see somebody unify the front end & ADC; you'd end up with a very modular front end that you could feed into an FPGA and go from there. I can imagine a lot of possibilities for that combo.
I think the large spanned heatsink is to cool the chips and keep all of the chips running at the same temperature, running a virtual differential low noise system..with the wafer fabrication of the ASICS, maybe
Really interesting that they are using Linux on the Rockchip and there is a JTAG, 4 pin port and 2 switches. That thing is probably easily hackable. I'll bet you can ssh into the OS from the 4 pin port.
Not a Tek 2 but still a very nicely built scope. I like the shielding and the way the PCB is designed.

Somehow this looks a bit like out of the Cyberpunk 2077 game. I like the look.
Seems FPGA memory bandwidth limited then, since 2x ADC and only 4GS/s in single channel mode. With dual ADC, 1ADC for 2 channels, 4GS/s should be possible in 2Channel mode, but FPGA interface/memory bandwidth likely sucks too much, for that ;-/
@@EEVblog They sent it knowing it was doomed to be dissected, so know the sticker is going to be sacrificed. They gave the strongest one they had though.
12:00 "Just a differential pair output buggering off there." That's the second usage of "buggering off" differential pairs used by Daiyve. Is the destination of the "buggering off pairs" the flying albatross on the PCB? Place your bets.
It says "QR code" on the silkscreen, but it's actually a Datamatrix code. It reads "ZRSPYHDO12209050003" w̶h̶i̶c̶h̶ ̶i̶s̶ ̶p̶r̶o̶b̶a̶b̶l̶y̶ ̶t̶h̶e̶ ̶s̶e̶r̶i̶a̶l̶. (2022-09-05? Third one off the line?) EDIT: My assumption above is wrong. The serial can be seen at 0:28 and is "HDO4A243700085"
That's because the hardware is an 800MHz scope, only the firmware limits it to 200MHz. You can buy a license code from Rigol and unlock the higher bandwidths.
It's using custom Rigol chips - what if they need to be replaced one day? it has BGA chips - so hard to fix if not impossible. The multitude of tiny switch mode power supply chips doesn't look durable to me. I've seen chips like that cooked on PCBs. As Dave says at 16:00 those tracks and parts look very whimpy for 50 ohm mode. Are they 5 thou tracks and tiny resistors? So could they burn out in some situations?
BGAs actually aren't too bad anymore; even if you're not comfortable with or don't have a good hot air gun they have a broad hoof attachment for most irons that let you take them off in seconds. Then you can stencil on some solder paste (stencils are optional, but cheap and helpful), heat it again to create the ball, and then plop it back down and zap it again quick with some heat and you're done!
I think the hardest part for me with custom chips is the supply. Dries up quickly after production and then you're dead in the water if you need one down the road.
@@Chilangosta - in theory that is OK but in practice it's hard to get a reliable repair. You can't see if your solder connections are all OK. Did you know that they check BGA connections with an X-Ray system in the factories?
@@Chilangosta - yes - they make only a certain number of chips and that's it. Factories will often order an extra 10% to keep as spare stock so they can do repairs and that's all there is. They use too many custom chips to cut down the cost of mass production. In the good old days design engineers would try their best to use chips that were available from at least 3 different sources but not anymore. Some chips now even need factory firmware to operate them too. You'd never be give that. The repair game is a thing of the past in many cases.
Just I thought but I bet the IQ at the end of the front end IC probably means its an IQ demodulator which explains the dual differential pair from each channel.

It's at the heart of a few single board computers too.
I wonder if the heatsinking could be more about minimising temperature for stability than having to dissipate a lot of heat
Maybe even have all inputs at the same temp, to reduce differences between the inputs on the same signal.
I also like the way they integrated heatsinking, temperature equalization and shielding into a single die-cast part.
@@aDaWaN Makes sense, after all a single spin cast mould that integrates it all is going to be cheaper in the assembly line, and you can get great dimensional stability in that single part as well so minimal machining work to get good results. You need a heat sink, so makes sense to have a single part then for the entire range, and it definitely cuts the cost down in assembly.

and you know what mate, at the age of 49 i can tell you this
DON'T WORRY ABOUT IT
Just keep being curious, Keep learning and Keep pulling shit apart, and sooner or later your brain will give you the answer
Truth is , at one point or another we are all geniuses
I get called a genius all the time, I'm not a genius , I just pay attention to shit
and just as you are now marvelling at me and dave and thinking that our knowledge surpasses your own
ONE DAY YOU WILL LEARN THIS SHIT AND SOMEONE WILL MARVEL AT YOU AS BEING A GENIUS AND HOW YOUR KNOWLEDGE SURPASSES THEIR OWN
and they will wonder "How can i ever be as smart as Omni Yambot"
See mate... it's all relative
We are not geniuses, it's just that people that have less knowledge than us see us and interpret THE DIFFERENCE IN KNOWLEDGE as "Genius"
LOL
The dictionary defines it as
EXCEPTIONAL INTELLECTUAL OR CREATIVE POWER
but what we have here is not EXCEPTIONAL KNOWLEDGE it's just
DIFFERENCE IN LEVEL OF KNOWLEDGE based on age and experience
therefore..... YOU TOO WILL ONE DAY BE A GENIUS
or... at least "Seem to be" LOL
don't worry about it mate, I'll happen, just do what you're doing and you'll get it
Somehow this looks a bit like out of the Cyberpunk 2077 game. I like the look.
There's even a third, nondescript, but populated button above the Rockchip. 👀
likely SAMSUNG or TSMC 7nm process given the size, and also the power it is outputting. likely a 10w part.
Puffin. The bird..
Aren’t they flightless like penguins? If so that might make it swimming rather than flying.
@@coryengel No, they fly. Very fast too - over 85 KPH.
Seems FPGA memory bandwidth limited then, since 2x ADC and only 4GS/s in single channel mode.
With dual ADC, 1ADC for 2 channels, 4GS/s should be possible in 2Channel mode, but FPGA interface/memory bandwidth likely sucks too much, for that ;-/
Battery pack is lithium ion and can last up to 4 hrs
I would be glad if you could digest a DSP car amplifier circuitry
0:38 On top, that is a nice Sharp boombox! Modelnumber?
Should have used a hairdryer on that security warrenty tab😂😂😂
Care factor ZERO!
@@EEVblog They sent it knowing it was doomed to be dissected, so know the sticker is going to be sacrificed. They gave the strongest one they had though.
12:00 "Just a differential pair output buggering off there." That's the second usage of "buggering off" differential pairs used by Daiyve. Is the destination of the "buggering off pairs" the flying albatross on the PCB? Place your bets.
24:25 is that QR code made with vias?
It says "QR code" on the silkscreen, but it's actually a Datamatrix code. It reads "ZRSPYHDO12209050003" w̶h̶i̶c̶h̶ ̶i̶s̶ ̶p̶r̶o̶b̶a̶b̶l̶y̶ ̶t̶h̶e̶ ̶s̶e̶r̶i̶a̶l̶. (2022-09-05? Third one off the line?)
EDIT: My assumption above is wrong. The serial can be seen at 0:28 and is "HDO4A243700085"
@@henninghoefer I don't know my 2D codes well enough to know the difference. I was just surprised by the way it was made, with vias.
I wander what's that component sitting between the main board cutout and the RJ-45 jack. Seems pretty isolated.
the lowest end HDO1000 Model will be 699. thats not bad,
"Floating Dave Head"...LMAO!
Why are there two differential pairs per front end channel?
Why would you want to add a DC bias to the frontend?
good for measuring low frequency noise/drift for power supply circuit?
I was also confused. Everything should be software controlled.
Maybe in a few years, fully hacked for cheap on ebay....
this bird ist a puffin
I'm confused Dave, you keep saying 800mhz scope, but it says 200mhz on the case?
That's because the hardware is an 800MHz scope, only the firmware limits it to 200MHz. You can buy a license code from Rigol and unlock the higher bandwidths.
It's using custom Rigol chips - what if they need to be replaced one day?
it has BGA chips - so hard to fix if not impossible.
The multitude of tiny switch mode power supply chips doesn't look durable to me.
I've seen chips like that cooked on PCBs.
As Dave says at 16:00 those tracks and parts look very whimpy for 50 ohm mode.
Are they 5 thou tracks and tiny resistors?
So could they burn out in some situations?
BGAs actually aren't too bad anymore; even if you're not comfortable with or don't have a good hot air gun they have a broad hoof attachment for most irons that let you take them off in seconds. Then you can stencil on some solder paste (stencils are optional, but cheap and helpful), heat it again to create the ball, and then plop it back down and zap it again quick with some heat and you're done!
I think the hardest part for me with custom chips is the supply. Dries up quickly after production and then you're dead in the water if you need one down the road.
@@Chilangosta - in theory that is OK but in practice it's hard to get a reliable repair.
You can't see if your solder connections are all OK.
Did you know that they check BGA connections with an X-Ray system in the factories?
@@Chilangosta - yes - they make only a certain number of chips and that's it.
Factories will often order an extra 10% to keep as spare stock
so they can do repairs and that's all there is.
They use too many custom chips to cut down the cost of mass production.
In the good old days design engineers would try their best to use chips
that were available from at least 3 different sources but not anymore.
Some chips now even need factory firmware to operate them too.
You'd never be give that.
The repair game is a thing of the past in many cases.
Dude, your SNR is like -42 dB
How do you test/prove 12 bit accuracy?
We where in, but not like flynn...
Just I thought but I bet the IQ at the end of the front end IC probably means its an IQ demodulator which explains the dual differential pair from each channel.
What? These things are using google's Android OS nowadays? Gee, guess I'm getting old
Hack it!! 🙏
You hack it by hand entering bits via the small pushbuttons on the board. This takes 12 hours, and if you make a mistake, the scope becomes bricked.
Didn't you JUST buy the thing?!
you mean to say you do not take apart new stuff immediately? its where all the cool stuff is
"Don't turn it on, take it apart!"
Each ADC four inputs!!!
Oh-oh .... my "Like" just put the count to 666
Dust?
wanna sell it. i just lost my house in sydney to a hurricane and need to buy a 121gw next week and you can send that with it. haha, funny, not funny. Sydney, Nova Scotia Canada. i had just bought a new siglent scope and needed a new dmm. if you do see this how long is shipping to canada from your store do ya know?
I'd love to see you hack this to run some Android apps on it.
seemly no serdes chips
I wonder how many osciloscope you have lol
Android? I would have bet they would use gnu/Linux..
Congratulations getting the Silicon manufactured I suppose.
Given that China is only interested in making
Yeah they cheaped out on the rock chip soc, it's a turd processor for bottom of the barrel tablets and cheap TVs, performance is horrible as well as software support
It may not be a high end SoC indeed but there was a time not so long ago when a scope did not need a 6 core 64-bit CPU running at 2 GHz 😉
@@MrJef06 and that's.how you get sluggish unresponsive UI as soon as you do anything than displaying a basic waveform. That manufacturers always cheaped out and put underperforming soc does not excuse them
SOO UNFORTUNATELY. THIERS ALWAYS AN UNFORTUNATE. THE RESON FOR THE HEAT SINKS AND FAN IS TO DRAW DIRT AND DUST IN AND OVER HEAT IT IN YEAR SO IT OVER HEATS AND YOU HAVE TO BUY NEXT YEARS MODEL. THAT'S THE REASON ALWAYS FOR THE FAN. ALWSYS. YOU CAN ALWAYS DESIGN ANY THING THAT RUNS COOLER OR HAS A FAN FILTER. THIS IS PURLEY TO KILL IT IN A YEARS TIME
when your osci is vulnerable to spectre....
