Re: Strange Tek part Numbers in an AM503B. Can anyone identify them
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

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. If the signal isn't the right amplitude to fit on the dotted line

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.

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

Re: Questions on impedance matching
Richard has nailed it. We still use power transmission when connecting a radio transmitter to an antenna, but we use voltage transmission for audio lines in studios. Dale H. Cook, Radio Contract

I don't want to trim this long thread because the context may be helpful to future readers. Its important to differentiate between voltage or current transmission and power transmission. Impedance

Re: Wanted 067-0681-01 Tunnel Diode Pulser by new member
It is quite possible to do that adjustment with your PG506's fast edge (maybe until you get a faster edge-generator). Make sure you have the appropriate attenuator(s) to be able and use the right
