1Ghz Keysight Pro-Gaming Oscilloscope with Liquid Cooling

Everyone in this thread is so angry, just let him do his thing lol

He can do whatever idiotic thing he can with his own money...

Problem is that Keysight donated fully functional 1 GHZ oscilloscope to this retard to destroy it....
Instead give it to the kid that won 1 st award on a local physic or electronics high school competition.

Morale of the story, let's be idiots...

[2N3055]

Quit whining ya'll. You are just jealous you didn't come up with it.  There are lots of equipment uphacking threads on this forum.

The watercooling system is an interesting idea. There is quite a bit of equipment out there with heatsinks and screeming fans just to cool a few devices. I can do without the LEDs for sure but it could be an interesting idea to get cooling directed at devices which need it the most.

I'd say A for effort. Pity that the RGB lit encoder knobs didn't work out. But the guy needs a financial donation to get his glasses fixed.

Some people just like to mod stuff. This car probably cost more than $20k and look what someone with a sick mind did to it:

Well, that's also an idiot..
Except Mercedes didn't donate this car to be destroyed. Some weirdo doing this to his own car is different from Mercedes sponsoring it...

No.  I'm stupefied by the uselessification of a wonderful tool.

Did they mod the scope to fit in a passively-cooled silent chassis, for anechoic chamber testing?  No.
Did they mod the scope to reduce its EMI and EMI sensitivity, for EMI chamber testing?  No.
Not even seeing if adding a grounded ITO layer in front of the display could remove the (little) EMI from the display (although that makes touch screens inoperable)?  No.
Did they mod the scope to sit nicely in a standard 19" rack, which everybody uses to build transportable test setups and even scientific experiments?  No.
Did they use the scope as a tool? No, they just wanted eye candy.

I just left academia, because while I am a pretty darn good simulator and research software tool developer, at least here nobody is interested in that: it is much easier to just buy more hardware (typically top-tier Nvidia gear for GPU computation), and use the same inefficient software we've had for the last two or three decades.  Talk about using a hammer to drive screws in... Like Keysight here, nobody is interested in actually modifying the tools so that they'd be better suited for the task, since it is easier to get funding for more new hardware instead.  Everything is measured using oddball metrics (like "views on Youtube", or the number of published papers per employee ignoring whether those papers are correct or need to be retracted later – those are Somebody Elses Problems).  Like with the blinged-out scope, it's easy to get attention by doing whatever everyone else is also already doing; at least then you're swimming with the flow, not against it.

And it's stupid: waste of an expensive tool, and a tool that many hobbyists like myself cannot afford.

(My current "scope" is an Analog Discovery 2 board.  I only do low voltage stuff, but I do need differential input in the 0..5 VDC range, for example for measuring gadgets' 5VDC current draw over a shunt resistor; typically the exact value isn't that interesting, as I'm more looking at the spikiness and fluctuation instead. Glitches in the current flow in the 10 Hz - 1 MHz frequency range, really.  A proper scope and a differential probe is > 1k€.  And if I save up to that, I better save up for a better model, so I can do rough EMI testing – at least comparative testing, to see if the device I'm working on produces less EMI than a known acceptable device.  And then I might be ready to get a reflow oven, and consider moving to 4/6-layer boards and BGA components.  So yeah, I am jealous of those who get free expensive tools, because I know how useful good tools are.  Seeing them converted to a Raspberry Pi Light Show is, frankly, pretty damn offensive.)

Well, if you listened carefully to the intro of the video then there are 2 things you should have picked up:
1) It is not a new oscilloscope from Keysight but one they use(d) as a prop for their videos. IOW: it is likely faulty/ broken in one or more ways and no longer suitable as lab equipment or even a prop. Note that later on in the video the guy mentions it shuts down every now and then.

2) Keysight has sponsored the video to attract more attention & contestants to their annual contest; that is how the project serves their purpose.

It might attract entrants, but does it attract buyers? I'm not sure people want to spend big bucks on exotic instruments sold with the "clown car" vibe.

At some point most people grow up and they will remember the brand. Mercedes has a whole bunch of merchandise for kids:

At some point they may want the real thing.

If you look more carefull you'll see a lot of brands will try to imprint on people at a young age because that is a cost effective thing to do. Tobacco manufacturers are notorious for this method of advertising.

I once did a practice poster on nanorheometers used in biophysics to study fluid/suspension flows in response to applied forces at the nanometer scale.  These are usually commercial atomic force microscopes converted to the purpose; sometimes just a matter of using different software, sometimes rather interesting hacks.  (IIRC, my poster had just a couple of examples of use, and focused on the modifications to AFM needed.)

I can imagine tons of different ways an expensive scope could be modified to work even better in a particular situation/environment, from clean room (say, hard drive recovery or similar) needs and acoustic/EMI measurement setups onwards.

Most manufacturers I've dealt with are horrified about anyone opening their enclosures (the warranty void stickers), and talking about adapting one of their high end devices to fit a specific need even better probably causes heart palpitations to their marketing teams.  I can see huge marketing value in doing that sort of a video, based on the interest my practice poster garnered in my fellow students at the time, and because it would be so different to the current industry marketing practices.  I still remember that practice poster session, because despite being about as interesting as dirt, the possibilities such a tool has made for a surprisingly lively discussion among various physics students, with lots of other "outside the box" ideas on modifying existing equipment voiced out loud.

Anyone who is interested in garnering publicity by adding Raspberry Pi RGB lights to a tool is a tool in my opinion.  That sort of stuff just clogs my bullshit filter.

Then again, I could be wrong.  Perhaps billions of flies are right, and dung actually does taste excellent.

Yeah well what else would you do with a DSO with only 4 Mpts of memory depth.

Probably but you'd have to start with a scope which isn't broken.

A couple of years ago there was a thread about an Ebay listing showing a Tektronix scope on which all the front panel controls where extended using long plastic rods. Probably the oscilloscope was at danger of carrying high voltages so someone choose to increase the isolation barrier to make it safe for the operator.

How quickly people forget scope on the bbq.

Thanks @newbrain for the PM

My thoughts & admissions of guilt:

1. I am 100% and solely the one that is behind this @Keysight

2. My personal opinion is that Zack does a great job with his channel and does some spectacular builds. The channel overall is not for everybody, and that's fine. If you don't like it, it's not for you. It has a very clear brand. I also do things with electroBOOM (and Dave, for that matter), and people have the same woes with all these channels.

3. I really like the build & the video.
- Is the scope as precise as before? Probably not (it's untested). Also he's not going to need the full bandwidth so it's ok if his is a bit detuned.
- Do I love it? Yes.
- Is 1 GHz overkill? 100% yes, but that's kind of the point. Also, it's what I had lying around so it's what he got.

4. Even though Zack may not be doing bleeding edge circuit work, I enjoy the channel for what it is. I know not everyone feels that way, so go support the channels you DO appreciate!

Keysight has sponsored the video to attract more attention & contestants to their annual contest; that is how the project serves their purpose.

Yes. I'm always looking for new channels / options, and want to support the community overall. Part of doing this type of thing is that it also allows me to spend budget to get equipment into the hands of the content creators in the community. From a "teach & build up the global community" standpoint, one scope in the hands of Dave is worth 20 scopes in the hands of non-video makers. Channels are working hard to both educate and entertain, and I love that I can use events like this to support those efforts. Of course there's a business perk as well, but that's what pays the bills. I'm here typing this at 12:30 AM because I want the community to be supported and grow, not because I want to push more scopes. That's a 9-5 thing.

Is Carly Fiorina back, now as head of marketing?

Yeah well what else would you do with a DSO with only 4 Mpts of memory depth. 

Somebody call the fire department

How quickly people forget scope on the bbq.

OG. I learned a lot from that! It was not a functional/usable scope so there was no real loss, but I still wouldn't do that again after the community response.

Edit: I've gotten more emails from Keysight folks about this video than every other promo video I've worked out, combined. Everyone that reached out to me loved it.

[Ice-Tea]

Cudos to Daniel for replying to what is not a sympathetic crowd 

That said, maybe next time give him a 100MHz scope or something. Might hurt a bit less

[2N3055]

I don't mind crazy and over the top. For instance I like watching Electroboom. And I am really happy Keysight sponsored him with instruments. He is respectful towards what is expensive and good quality stuff...And he shows respect towards Keysight every time he speaks about it..

And in addition to that, I wouldn't even speak up about it if this guy made some really cool looking steampunk or something artistic, with real and proper artistic and manufacturing skills. What he did is cheap, below average 3D printing, cheesy colours...etc. It literally looks like it was done by 5 year old. The rest of his projects are also 

This video of his starts with sentence: "I had one weekend to build professional quality video controller..."



Nuff said... In my mind he was not worthy...  That's all... I realize it wasn't my choice to make, but, hey free speech and such..

Somebody like Bad Dog Designs would make an awesome job of a 'scope but it wouldn't be a weekend's work.

Kudos to Daniel for replying and explaining as you say but it still burns that $18K of scope was given away to be ruined for clicks when most people and many businesses will *never* be able to afford something like that.

I love his stuff! I've been eyeing it on Twitter for a while, that would be a super cool collab.

I vote for modding a PSU 

[electr_peter]

I would point out that Dave from EEBblog may have started visual scope modification theme with custom front panel graphics and boot screen image.

Everyone has different taste for aesthetics. Personally I am not huge fan of RGB in everything, but modifications attracts attention from broader community.
I would say that person forgot to change boot screen image (at least I did not see that)

[NiHaoMike]

I vote for modding a PSU 

Already commonly done, but apart from the (relatively) small percentage who do power electronics, that stuff just isn't that interesting. It's usually looked at as part of something more interesting, such as modifying a cheap HP server PSU to use on a CR-10 3D printer, then replacing the heated bed with one of a higher power rating so it doesn't take as long to warm up.

Is pineapple fried rice also an abomination?

My favorite kinds of pizza have pineapple on them. I'm not sure why some people find that so vile, or care. Lots of Polynesian foods combine pineapple with meat too.
