Ok. Let’s try this again…RCA 9TC240 Alignment

OK, well inhibit isn't going to work with your scope and you have nothing on the vertical so all you will see is a horizontal line. Meaning that, so far, it looks like it should.

But I don't see markers...Penthode showed this setup without a vertical input and he had 5 markers on the horizontal trace. That's what I'm trying to reproduce but there are no markers.

Correct. You will NOT see markers using the setup he outlined using a digital scope. You cannot reproduce it using the HP digital scope using the inhibit technique.

I suggest you try connecting the Z-axis output to the z-axis input on the digital scope. If that doesn't work, you will have to use an analog scope.

Yes, a 465 or 2213 will work. Rotate the timebase on the 2213 to XY

Z axis input on the scope? Where is that? I have 3 BNC inputs on the scope…X Y and external trigger
