If I were to try that, I'd first look at flash a/d converters, at least 8 bits if not more.? That gives you a digital output of the X and Y channels (scale input first!).? For an FPGA, I'd suggest

That's PIC17C42A 33MHz PLCC in Industrial or Extended Temperature range Must be unused as they are OTP parts. Thanks David

hi Walter, I have been thinking about a possible replacement video display panel for the Tek 576 CRT : It would require some cpu or processor ( A/D, logic, etc.) to translate, format and communicate

Okay - I see that in the parts list now. It isn't shown on the pictorial diagram and I don't see it on at least one of the boards I have either. It's listed as "NOMINAL, INSTALLED, TEST SELECTED" so,

it is a ferrite core which prevents high frequency oscillations, I believe. G?ran

In the manual for the 7B53A/7B53AN, the #2 schematic for the Main Trigger Generator (for SN B209999 & Below on page 124 of the version of that manual I'm viewing) shows a small rotated rectangle

You linked to the black one which only goes up to 16mm. It doesn't matter. It proves nothing. The fact that some fly by night corner shop in China doesn't have a specific screw doesn't mean someone

The usual rule for fault finding is 'first check all low voltage DC supplies for correct voltage and ripple'. Particularly relevant in this case! It is not clear why you have two spots. Are you

Mark, Thanks for the rundown. I have not tried again to address the TIME/DIV issues on the new 7B92, concentrating instead on diagnosing the old 7B92 by swapping boards (I will get to the new 7B92 in

Roy, I will have to respectfully disagree with the statement that the 57X units have been replaced and usurped. However to establish my personal bias I will have to admin that I have more than one of

Albert, I had been looking at it with the side cover removed; however, I just went out and turned the scope on its left side and that gave me a slightly better view. While it's a bit hard to see, I

Barry, H?kan already mentioned that the protruding part with the 4 holes plays no role at all (in positioning of the rear of the plugin). When you push the plugin into the scope the rear of the

Keith, I don't have access to the 531 CRTs specs, so hard to say how good a fit it might be into the 575, BUT I suspect the vertical deflection will be clipped by the physical plates, and that it will

Interesting video. I'd say, they are sure putting lipstick on the pig with that fancy GUI they have coded up. I'd reckon 90% of the fiddly work went into knocking the bugs out of that. The rest of it

well the replacement transistors are fitted,i now hove the trace for want of a better word adjustable but now have no sweep,did i mention i put the scope down on a pice of coiled solder wire,it

Well... given the prices that some people pay for these... and unless its on one end of a chain... and sometimes on the bottom of the pond (just cause you can afford it)... I just don't see why, if it

Albert, I looked again at two of my plugins - this badly broken one and an intact one. The one without that upper protrusion is quite difficult to push into the back socket due to it being slightly

Barry, As an example of what H?kan says you might look here: https://w140.com/tekwiki/wiki/067-0587-10#/media/File:067-0587-10_11k_mod_rear.jpg The rear part is translucent plastic now (at least in

If I'm not mistaken, that protruding part provides an initial "lift" so that the rest of the aligning surfaces can start correctly. I'm pretty sure this one wasn't purposefully cut off but was more

That doesn't has any purpose in most 7k plugins. Chances are that it was deliberately cut off since that's what had to be done for the plugin to fit and work in an 11000 mainframe. /H?kan
