I was thinking the same thing! It looks so organic and natural. From a VFX standpoint, it's like a cross-fade applied to vector coordinates instead of pixel values. Or something. I think it's something that is fundamentally very simple, but it's something we pretty much never, ever get to see.
You probably dont give a shit but does anyone know of a way to log back into an Instagram account? I was stupid lost my account password. I would appreciate any tips you can give me!
Great info that I again I did not know: digital scope xy mode issues and work arounds. I notice products are not normally promoted for sale and this video channel. So I looked up VintageTEK on ebay and their website realizing that the promotion might be important. I see that the group is doing our electronics community such a useful service so I bought one of the logo display boards with Pong simulation partly just as a donation to the cause. But I am sure using the board will teach me even more detail and practical lab procedure.
Very cool, brings me back to my college days (early 90s), 3rd year cpu digital design course, we were assigned a year end class project to display and animate the schools name (SVSU) the Class name (EE 355 I think) and our initials on an oscilloscope using a 8086 training board and an interface circuit that we had to design. As I recall it was a pretty straight forward project with respect to the interface but a real challenge to program because it was all done via 8086 assembly straight into the training board. If I only knew then what I know now it would have been much easier.
That must be Bob Haas.. I worked alongside him for many years at his previous workplace prior to him retiring and devoting his time to the Tek Museum, right down the street inside the Tek Campus. Small world.
Follow-up since I've just received my little demo board from the guys at VintageTEK, and even though I didn't really need it, they were thoughtful enough to include a french version of the instructions (nice touch). I'm powering it with a soldered on cable that plugs into a small USB PSU at the other end (inexpensive and practical way to easily get a +5VDC supply when not on my bench). And on my Rigol DS-1054Z it looks better than I expected, although a tiny bit noisy (because the scope itself is that way, an expensive Tektronix MDO4104C this is definitely not). I couldn't get the averaging morphing, sadly. But it makes for a nice exhibit when tech friends come over...
Fun and informative little video ! The averaging morphing is a neat effect. Thanks for sharing ! My scope is a Rigol DS1054 and it is digital, but I'm curious to see how it's going to display this. Ordered one. It'll be my small contribution to the museum.
Thanks w2aew! Was going to build the octopus device in order to visualize lissajous patterns on my Rigol DS1054z, now I know one reason that the waveform might look weird.
Another gadget I just had to have! I tried Alan's Arduino experiment about this same topic a couple of years ago and it was cool...couldn't resist getting the Tek group's version to compare my Tek 2440 and Rigol displays in the XY mode. Actually both are tricky to use in the XY mode, not like my old basic analog scope I used for years with a spectrum analyzer attachment; luckily I still had my old notes on how to set up the 2440 to use the analyzer or I probably never would have figured it out again! Thanks Alan, another great video! 73 - Dino KL0S
Vintage Tek doesn't seem to have the display board anymore or the update either. Someone used to make a gadget that could display a clock on the screen too.
Nice one, as always, Alan! I ordered one of the nifty little circuits more to give my scopes (and me) a bit of X-Y exercise (a function I seldom use) than to show off what I can do with them. Can it be modified into displaying different images, do you know?
I am not sure where I saw this, but I worked with a scope (rather expensive one) with xy mode that did not only points, but lines and had a velocity control for the lines, so the longer the line, the fainter it was. This one together with some enabled view persistence looked really analogue like. I think it even supported a third channel as Z...
hello from the other side of the earth no words will show my thankfulness i have watched and learned a lot from most of your videos i need a video also about MOSFET false turn on due to the dv/dt i will repeat this comment in videos i have seen this morning in my country so you can them also this is the only support i have for you for now
This is a few years after you posted this. I bought the demo board and have used it for demo only. However I didn't realize it might have the game and menu. I have searched pretty extensively and can not find any info on hooking up any switched or potentiometers. Do you have any information on that. Also I enjoy your videos a lot, but you have cost me some money. I have bought a few items because of your videos, I also enjoy when you appear W5KUB. On another note my DS1102 E does really poor on displaying this. I is interesting that of course the time base has no effect on my analog scope the "Time" control shows the effect of memory greatly in the number of points displayed on the Rigol DS 1102E. Thanks Garry
I think that only the later-produced boards had the game implemented. At the time this video was produced, the module didn't have the game. And yes, digital scopes do a poor job of XY, and the dependence on the waveform memory is one of the main reasons why.
Hi, I have a question that may seem strange can we see not repeatitive high frequency signals in low frequency oscilloscopes is there any idea or device?
I guess that playing with the brightness control and the beam speed you can do this kind of drawings without using the Z channel on an analog scope but in the digital scope, why the drawing is not shown as a single continous stroke?
One of the things I really like with analog scopes is buttons. Good old mechanical buttons with nice feedback and build quality. These newer rubber buttons are meh.
The waveforms don't instantaeously change voltage, so you will get samples showing up where the "trace" is moving quickly from one point to another. These are the parts of the figure that don't show up in an analog scope because the beam moves too quickly to light up the phosphor (unless you tune the brightness way up), but you will see samples that land on these fast edges with the digital scope.
Scope porn. Love it! Six left on eBay -- I got mine. I will make an offering of this novel circuit to my TEK 2467BHD, the warden of the lab. A fun way to demo analog to newcomers. Thanks for a fun video.
w2aew Less recently, traced portion of the image is fading out and freshly traced portion is brighter. Probably, that's why that moving gradient. Infinite persistence might make full x y area bright without any image. Persistance with Z input modulation will form proper image.
Yes, infinite persistance would definitely help, but since this board generates two XY images, you'd wind up with overlapping images on the display. And, this older scope does not have Z-axis modulation.
Hello good sir. In an unrelated subject, I just received a very much abused by inexpert hands Tektronix 2336 100 MHz scope. Is this particular model worth an attempted restoration? It is in very rough shape.....
I guess XY mode isn't as important anymore nowadays. Aren't there any digital scopes that can do a time based intensity grading (making the point or connecting line to it darker the "older" it is)? That is essentially what the phosphor does on analog scopes.
Many scopes have intensity grading of the waveforms to emulate the phosphor on the analog CRTs. There are even a few that have a some Z axis control...
Carl Davis - I’m an old-timer with some “vintage Tek gear” so I feel your mood. But what, exactly, is better about a 400 series than say, a 6 GHz modern ‘scope? Seriously, what is better? I have every curve tracer Tek ever made beginning with the 575. Frankly, the VT stuff is hideous. The 577 has some nice IV extreme performance. However, I can’t buy parts today that make those beefy front porches worth a damn. You do young people a disservice speaking in absolute terms when all your doing is showing off your nostalgia. Pony up on “better” or fade away where you can’t hurt anyone’s future.
You need to read between the lines. Notice where I said I tried this a year ago. I am talking about putting the device covered in this video on a 465 a TDS784C and a TDS2024B. It took seconds to get the logo on the 465 and minutes of fiddling to get it on the other two. In this case for me the 465 was superior. Seconds to minutes of fiddling. That is why the 465 is better in this case, and I wrote this based on this specific case. What can I say. I hate having to write more than just a post like I am writing this deluge now. But I guess it is necessary for some folks who can't understand what is being implied based on the video just watched.
That transition was awesome!
I was thinking the same thing! It looks so organic and natural. From a VFX standpoint, it's like a cross-fade applied to vector coordinates instead of pixel values. Or something. I think it's something that is fundamentally very simple, but it's something we pretty much never, ever get to see.

@Jase Jesse Instablaster :)
A wonderful mix of teaching, technologies, and nostalgia! Thank you!
Agree
You have showed me something I have not done my whole electronics life with oscilloscopes and never expected to see like this. Great thanks...
Great info that I again I did not know: digital scope xy mode issues and work arounds. I notice products are not normally promoted for sale and this video channel.

My tektronix 2232 has the wizard and Tex bug in the hidden menu. That’s so cool they put it in there.
Very cool, brings me back to my college days (early 90s), 3rd year cpu digital design course, we were assigned a year end class project to display and animate the schools name (SVSU) the Class name (EE 355 I think) and our initials on an oscilloscope using a 8086 training board and an interface circuit that we had to design.

I have purchased from Vintage Tek, great plug. Those guys are fantastic.
Thank you for this Alan. Very cool transition effect. I am glad to put the first comment in, my advantage being where I live
That must be Bob Haas.. I worked alongside him for many years at his previous workplace prior to him retiring and devoting his time to the Tek Museum, right down the street inside the Tek Campus. Small world.
Yes, you're right.

I'm actually doing fundamental labs with my first year electronic students and will be looking at XY in few weeks
My Tek 2221A has the wizard and Tek logo built in as an Easter egg.
Interesting and fun video Alan. Thumbs up!

Could be fun to see the morph on more than 8 samples in the average mode, but very nice video.
As always absolutely excellent explanations without the "umm's, ah's etc. Thank you for the elucidation you provide on each & every video.
Neat stuff Alan! Thanks for sharing!
that average mode on the last scope looks very cool! it's like a picture morph.
I hope the board becomes available again some day.
Vintage Tek doesn't seem to have the display board anymore or the update either. Someone used to make a gadget that could display a clock on the screen too.
Nice video .. just might order one. Keep up your fantastic work!
I did!
Very cool. I saw this in one of your earlier videos so I jumped at getting one of these from eBay!
not available for now, any idea where I can get one of these?
@@alt0v14 Try emailing contactus@vintagetek.org to see if they are planning to make these available again.
Hi Alan,
Enjoyed the video, especially when you showed the morphing using the averaging mode. :-) 73 WB3BJU
Nice one, as always, Alan! I ordered one of the nifty little circuits more to give my scopes (and me) a bit of X-Y exercise (a function I seldom use) than to show off what I can do with them. Can it be modified into displaying different images, do you know?
Thanks Alan.
"Digital Etch-a-sketch"....love it..
Great video Alan as always. Someday I will have enough to buy a MDO series tektronik .
You need not buy any digital but buy Analog with cursor readout feature will be enough.
That averaging on the MDO looks like a Scanimate transition.
My Tektronix scope has both the wizard and tek bug. The wizard actually skates around.
I am not sure where I saw this, but I worked with a scope (rather expensive one) with xy mode that did not only points, but lines and had a velocity control for the lines, so the longer the line, the fainter it was. This one together with some enabled view persistence looked really analogue like. I think it even supported a third channel as Z...
hello from the other side of the earth
no words will show my thankfulness
i have watched and learned a lot from most of your videos
i need a video also about MOSFET false turn on due to the dv/dt
i will repeat this comment in videos i have seen this morning in my country so you can them also this is the only support i have for you for now
Great Circuit!
The Average feature is neat. Advantage of digital multimeters is the smaller size, like the pocket Velleman ones.
awesome video
This is genius. I now understand xy mode.
Thanks Alan! I learned a lot! 👌
The same is true for emulating old vector arcade games, it's pretty difficult to get a decent emulation.
This is a few years after you posted this. I bought the demo board and have used it for demo only. However I didn't realize it might have the game and menu. I have searched pretty
extensively and can not find any info on hooking up any switched or potentiometers.
Do you have any information on that. Also I enjoy your videos a lot, but you have cost me some money. I have bought a few items because of your videos, I also enjoy when you appear

Thanks for this vedio.wawhat is x-y mode of an oscilloscope
i used to have an electronic etch-a-sketch ;)
I guess that playing with the brightness control and the beam speed you can do this kind of drawings without using the Z channel on an analog scope but in the digital scope, why the drawing is not shown as a single continous stroke?
Excellent
You should try jerobeam fenderson's scope music on these!
Thanks for the reality check.
There's still a bunch of folks in denial but hopefully this clears things up.
Over 4,000 views and 600 likes in 24 hours .. impressive at multiple levels!
Great vid.... but link for that item says "is no longer available"..
Yeah, looks like they sold out. Check back in the future, they'll probably build another lot of them soon.
Thanks my friend...!!
One of the things I really like with analog scopes is buttons. Good old mechanical buttons with nice feedback and build quality. These newer rubber buttons are meh.
All sold out on Ebay. That was quick . Great video. Thanks.
Yeah, looks like they sold out. Check back in the future, they'll probably build another lot of them soon.
Interesting and informative video...Thank You! What causes the small, faint dots roaming around when you switched to the MDO scope?
The waveforms don't instantaeously change voltage, so you will get samples showing up where the "trace" is moving quickly from one point to another. These are the parts of the figure that don't show up in an analog scope because the beam moves too quickly to light up the phosphor (unless you tune the brightness way up), but you will see samples that land on these fast edges with the digital scope.
Understood! Thank you very much for your reply!
Scope porn. Love it! Six left on eBay -- I got mine. I will make an offering of this novel circuit to my TEK 2467BHD, the warden of the lab. A fun way to demo analog to newcomers. Thanks for a fun video.
Is the link to the video generator board right?
Unfortunately, I believe they sold out. More info available in my video #164 (see the notes).
Intresting..., Did you try turning ON persistence on digital scope ?
I did on the TDS2000. Wasn't necessary on the 4000.
w2aew Less recently, traced portion of the image is fading out and freshly traced portion is brighter. Probably, that's why that moving gradient. Infinite persistence might make full x y area bright without any image. Persistance with Z input modulation will form proper image.
Yes, infinite persistance would definitely help, but since this board generates two XY images, you'd wind up with overlapping images on the display. And, this older scope does not have Z-axis modulation.
Are those boards still available?
I think they've sold out, but it couldn't hurt contacting VintageTek to see if they have any more of them.
very nice
I'm sorry for asking such a basic question but what is this thing and what does it do?
It's called an oscilloscope. It is used by engineers, technicians and even hobbyists to examine voltage changes vs. time in electronic circuits.
Hello good sir. In an unrelated subject, I just received a very much abused by inexpert hands Tektronix 2336 100 MHz scope. Is this particular model worth an attempted restoration? It is in very rough shape.....
It's a nice portable, I would think it would be worth fixing up.
i have seen some guy which put in AV video into an analog scope, can you do that too?
(he didnt reply how he did it)
Glad I have my 2247A. Does a better job with X-Y. The morphing is a nice affect though.
Let me know if oscilloscope is a black and white CRT TV sir ????????????????
old CRT based oscilloscopes use similar technology as a CRT TV, but the deflection system and phosphor type is very different.
Unfortunately, neither link showed the board you mentioned. OOPS! I gave you a thumbs-Up anyway.
They sold out already.
It’s a hard thing to explain. Especially to people born after analog ‘scopes were out of production. Thank you.
this is like ILDA laser display😁👍😎
Cool.
interesting!
@2:30 This scope is 15 beers older .. hehe :)
I guess XY mode isn't as important anymore nowadays. Aren't there any digital scopes that can do a time based intensity grading (making the point or connecting line to it darker the "older" it is)? That is essentially what the phosphor does on analog scopes.

My 465 was better than any of the newer digital I own. I tried this a year ago. I also built your analog video piece. You should tout that again.
