i always hated memorizing alot of math "forms" and grinding out long equations. im still into making the final adjustments on the test bench. before personal com,puters. unless you had a way of

We used the Standard Amplitude Calibrator on the bench in Test-Final to cal the instruments after being cycled. There was no proceedure known to me that used the amplifier section of the SAC and I

I think there was more to it than simply omitting the amp. Stan has several -00's in which it was deliberately removed. This has always mystified me. Perhaps it failed to meet spec so egregiously that

Hi Does anyone know what the primary resistance is for T620 is. The power supply in mine doesn't work right. I have 500 volts at the plate of the 6dq6 and the thing is oscillating after I replaced

012-0649-00: CABLE ASSY,RF; 50 OHM COAX,28.5 L SMA BOTH ENDS "MEETS REQUIREMENTS FOR TYPE RG-223/U CABLE AS SPECIFIED IN MIL-C-17D AND MIL-C-17/84." This is a purchased cable, so the _exact_ cable is

The guy has a point that this is all pretty basic stuff. But then "pretty basic" means a lot of things to a lot of people -- so it's then a social issue to filter one's own mutterings :) I'm guilty as

If x^2=y, then sqrt(y)=x -1^2 is definitely not -1, so it makes no sense for sqrt(-1) being -1. To support negative y's, you need a special factor for x: x then becomes a product of this special

I remember Feynman talking about this lesson, that his father taught him as a small boy. Feynman was distressed while walking one day with his father that one of his friends had made him feel dumb

Or, putting it another way, dimensions aren't vectors: they have no direction. Cheers, Kuba

Methinks that once you get the underlying concepts straght, you'll see it the other way. Nope, and I'm bewildered as to why you'd think that way. You get a very ordinary square with positive

I doubt that. They know how to use it, but they likely have no more understanding than anyone else. There's a difference between knowing how to apply something, and understanding it. I'd hazard a

Todd, Go to ftp://bama.sbc.edu/downloads/tek/464/ Download the manual. If you don't have the viewer, Go to Lizardtech. Check the power supply voltages. Look in the manual for troubleshooting

I think their frequency response is somewhat limited (kHz), and of course they are nonlinear and lack sensitivity at the beginning of the travel, but otherwise they are great. I keep several for

iron vane meters are still being manufactured for panel meter applications. "simpson electric and other manufactures" they are genuine true rms responding. a simpson 260 multimeter is not true rms

Hi Arthur, It isn't really what I believe that counts here. I was just repeating what Tektronix has written in the service manual for 555 required equipment. I think they specify an Iron vane movement

check to see if it will work in x/y mode "don t burn the tube"

Well, To make a long story short, I"ve been trying to get a newly aquired 464 up and running which now has no sweep. I recieved the scope last month and seemed to function perfectly until last week

That's a bit surprising; do you have an operator's manual for it? I'll look around on my shelf and see what I have in the way of 2750-series docs, but I'm not immediately optimistic. 200 Hz. This is
