My opinion is you should buy it if you have any interest in owning a curve tracer, as that is a very good deal! tom jobe...

I believe I may have an opportunity to acquire a 577 D2 for $200 if anyone has an opinion on that. Thanks all. David

The one 7K CRT that does not ship well inside it frame is the 7104. I've bought two that the rear was hit hard enough to shatter the CRT. Got full credit but still sucks [email protected]> wrote:

I had been working on this 465 (SN B175976) for a few days. I had replaced a burned out input resistor on one channel and tightened a shaft coupling. After that it was more or less working, but I was

If the signal isn't the right amplitude to fit on the dotted line markers, the temptation is to change the vertical gain using the VAR gain control. Unfortunately in many scopes that will also change

Hi 160-9569 is the whole processor, including OTP ROM. I was able to read mine, i posted the bin on www.ko4bb.com. You can find it as Tektronix_AM503B_current_probe_amplifier_EPROM.zip The processor

Hi?I would like to help you out in this scope project you have there , but i do not have the time to part out scope as you would like me to . In addition shipping the crt like that can be

Thanks lop pol for correcting me. I didn't think about the link to the video. It's not one of Alan's best videos I have to say: You can see the edge shape change (causing rise time to change with it)

I'm not going to spend 13 minutes off my remaining life to see exactly what was done in that video, but there is a trap in this area. I think he was referring to to video siggi linked. Which indeed

Hi Oliver What do you think if i buy the scope, and you part out it? My friends are outside of US now for work reasons. The equipment is very big and very heavy for delivery. So, if you accept, i will

Tom, They are photographs, not video. From what I can see in the picture, lop pol used a fixed attenuator and reduced the amplitude further with the variable output level adjustment of the PG506. That

Hello, The 165-2456-00 is also used in the AM503A, and is described as "based on M377" in the service manual, http://w140.com/am503a_service.pdf The M377 derivatives are used in several 11Axx plugins

Hi lop pol (and Siggi), I decided to repeat your experiments as best I could. I used one of my PG506'es. I know it to have a rise time of about 750 ps. I used an S-52 pulse generator head as a pulser.

Dennis, The instruction manual says the 160-9569 is a prom. The manufacturer is listed as Tek. The manual is on the Tek website. Bob.  

Hey Lol, Your nice old 485s come equipped with graticule markers specifically for rise time measurement. See this video <https://youtu.be/eRA1Mx506fw> for how to use them to get repeatable and

Hi lop pol, Thanks for doing the tests. I don't understand the outcome, however. Just looking at your images: In the TD (tunneldiode pulser) image, assuming a TD rt of 100ps (<=125ps specified), I see
