Hi, Jim. I used many resources and tutorials - YouTube has many good tutorials for beginners. There is Python and there is PYQT5. PYQT5 allows you to build a Graphical User Interface (GUI) easily. -

Hello Michael and the Group, there is a review of this ZD-985 on youtube. https://www.youtube.com/watch?v=Ft50m8UU5WQ An old workmate of mine bought one and he is delighted with the performance of

Dennis, Thanks for weighing in on this one. I was thinking the same thing, that it is easy to talk about it, but much more difficult to make it work, as you have already stated. They have added a

Hi mosaicmerc: I'm interested. I have a couple of them that I need to fix. Best regards and wishes. Roy

I've thought of making an LCD replacement for the 576 CRT. It would be pretty neat, you could add a touch screen interface and calculate the parameters on the fly (quite possible since you could get

Hello Jean-Paul, Not to dissuade you from getting a good desoldering tool, but before you do that, get yourself some Chip Quik. Chip Quik is very low temperature solder that readily alloys with

Hi Rick, Thanks for pointing out this video. It is interesting for many reasons. * How many people would tack on an additional $2,000 on top of $2,000 that this company sells a used 576 for. There is

Hi, John.With your experience writing Python code, maybe you could point me in the right direction.  I'm trying to learn Python so I can control my test equipment over GPIB and USB.  I downloaded a

I bought the fr301 new on the bay for around 250. Works great, tons of vids on youtube too showing operation & disassembly (fr300 is similar to 301) The best part about the 301 compared to the

I think the voltages need to be picked off before they get to the deflection plates. If you digitize the signals and send them across the serial interface using an Arduino, all you need to do on the

regarding the 2235 secondary psu rectifiers: YES, it is possible to see leaky, shorted or open secondary supply rectifiers, which results in big ripple.  this is FAR less common than bad caps (over

and sorry, but i dont have access to a VTVM :( surely if my meter cant measure across it, then there at least isnt a catastrophic short? gmail.com@groups.io> wrote:

Lin, Would it not be a simple matter to somehow convert the 576 deflection plate voltage signals to X-Y Data? Just thinking out loud here. I would guess that you are 100% correct in your thinking

also anyone know where B1473-75 are? looks like tek added some neon bulbs there to make sure the grid didnt go above K, but i dont know what theyre doing now... gmail.com@groups.io> wrote:

You don't really need to worry a lot about it. Use the arduino serial write to get the data to the PC. Then in whatever program you use, be it pascal, visual basic, or what, open a com port for the

I am fairly certain its the HV by this point, mike, since my -1960v is only around 1800v. I meant the front panel intensity control with the touchy wiper. I'm currently trying to ascertain the best

I find it very surprising that the 576 doesn't have an X-Y output for a plotter. These were common in the 60s-70s and I guess even in the 80s, before GPIB became common place. For instance, my HP3580A

The big advantage of the 576 is that it is solid state and the logic is TTL, so it may be easier to work directly with the ARDUINO than it might prove with the 575, just taking a guess on that . The

Jack, in response to your email of 1:33 pm: I think it's possible that your "excessive trace brightness" problem could be an issue with HV circuit component failure (as others have suggested), and/or

I am cheap, so I took a chance on a CCC (Cheap Chinese Crap) ZD-985 Vacuum desolder station @ about $119.00 (about 2 years ago) delivered in 2 days. Amazon has a great return policy, so when I got
