someone just released a really cool "oscilloscope music" album on youtube. it's audio that is music AND vector graphics at the same time. it'd look pretty great on that large XY monitor.
That is really working well, good OLD HP quality. Yes, vector to raster comparisons are hard, but what has been measured on the Tek 4000 series of storage vector graphics terminals and computers was roughly 1280x1024 on a 12" 1600x1200 14" 4800x3840 19" 25" (Who knows never made but prototyped). The high resolution is why you would see the terminals on CAD systems into the early 90s if you see footage on say the 737-500 design, but not on the 777 which used an updated CAD system (Catia) that ran on IBM RS-6000 machines. which had high end trinitron raster displays.
A few drops of Fader 5 along the plastic guides to CB eases the removal and saves the plastic. Its works like a champ. Excellent content. You help fill in some gaps for me when explaining the operation.
Great..... JUST GREAT!!! Now I'll be forever looking for one of these......... My previous ignorance of this HP display was a blessing! 😁 90% of my test equipment is fully restored HP/Agilent. I LOVE their original design philosophy, and while I do own Tektronix scopes as well, I do believe HP was just designed and built better. At least from a servicing point of view. I was happy, Bob! I was fine..... until you had to post THIS!!! 🤣
Fascinating! This is vaguely reminiscent of some of the videos I've seen of techs working on vintage arcade game vector CRT circuits in consoles from the late 1970's/early 1980's. They didn't seem quite as complex as this, though.
28.5 kV is correct for the accelerating potential. +24kV on the second anode, -4.5kV on the cathode. Use of a bipolar accelerating supply is common on electrostatic CRTs, so that the deflection plates can operate near ground potential at zero deflection. I believe this tube uses a scan expansion mesh at the front of the gun to allow wide deflection with the high accelerating potential.
Wow Bob, I'm glad that was such an easy fix! I'm not exactly sure of the actual problem was, those edge connectors are gold plated, which are used to keep the connection alive with microamp currents flowing. Hopefully it doesn't fail at some point. I was greatly surprised at the circuitry; it's all discrete transistors and very repairable. HP was famous for manufacturing custom modules in their clean rooms, foiling repair attempts if replacement parts were not available. All the sinewaves on the monitor reminded me of the Outer Limits show from the early 1960's. That show always gave me nightmares as a kid.
Looking at the picture, the case would have snapped into the woodgrain covered rails, leaving them on the outside, so my guess is that at some point it would have had a case.
Look at 4:42 in the video. With the right circuitry to drive it, they could draw precise graphs, and draw text labels, all with X-Y vector graphics. In that picture it's simply displaying a larger version of what's on the instrument below, but in other applications it might be the only display. It's not really meant to be a standalone instrument. It's used as a monitor, and some external device is needed to provide signals to draw whatever is needed for whatever application you use it for.

From your deepest shed, to the Outer Limits!
Cliff Robertson in the Galaxy Being episode would be proud!
@@chetpomeroy1399 Just don't turn up the power all the way, it would be... BAD! :o
First thing I always do with Tek and HP equipment is to reseat all the connectors and cards. It has fixed many problems for me.
We control the vertical, we control the horizontal... Very cool, Bob!! Makes me think of a Tempest or Asteroids cabinet...
Don't forget Battlezone and Red Baron.
I used to love it when whatever I dragged home actually worked without doing anything😀 Watching now.
Cool Piece of gear !!

Beautiful! Please put some oscilloscope music on it! Ideally, you need a DC coupled DAC to show it properly (and a disabled screen protector).

Vector arcade games are usually magnetic deflection and presumably run at much lower frequencies.
28.5 kV is correct for the accelerating potential. +24kV on the second anode, -4.5kV on the cathode. Use of a bipolar accelerating supply is common on electrostatic CRTs, so that the deflection plates can operate near ground potential at zero deflection. I believe this tube uses a scan expansion mesh at the front of the gun to allow wide deflection with the high accelerating potential.
Right, that explains the 8,000 volt cap on the z-axis input.

Yes, it is odd. Perhaps the problem was with the push on connectors going to the BNC jack.

I should've bought it when I saw it :) Nah, just joking... nice score Bob... A spectrum analyzer would look great on this screen, or an XY clock ;)
Hey Bob, a little slow here. Was this essentially an aux monitor for scopes in general? Or is this a proper xy scope?
XY monitor. You wouldn't use it with a scope. Specialized imaging like electron microscope.
@@bandersentv Ah makes sense. I saw that photo and of course starting thinking oooh that would be a nice addition to my 3582A. Big monitor=better
