From Zenith's data sheet, the tunnel diode is a 152-0099-00, which is a 50mA/6pF device. Calculated switching time for this would be faster than 60ps - but it all depends on the layout. Any

Hello Miro Best deal is to use an activated flux (acid) you need so little flux on the tip of the solder that you can't even see it. Just tin the nickel plate or stainless of the cell and finish the

Do not forget lubricant, it is amazing what a little bit of grease can do for sliding. I am not sure what would be the best or recommended grease for those switches, but I would try (thick) silicon

I picked up a Tek 017-086 TD pulser a while back. It is self contained and about twice the size of its GR connector. Power is from 2 internal coin cells. Risetime printed on it is <.2ns (200ps). It

Hello Ed, Here is what I have on TU-5, a data sheet that I got on this list. I have a hulk of a TU-5 and it does have BNC connectors; perhaps in earlier version this unit had UHF connectors. Be

Hi, gang, With thanks to Guido Kueppers, the following additional file(s) is/are now available on the Blue Feather FTP archive at ftp.bluefeathertech.com. File name: 12RC11_U140.bin Path:

Didn't realize this stuff was so valuable. I have a few items I could probably be bribed out of. Self contained 30ps pulser works http://nm7u.tripod.com/homepage/td1.jpg http://nm7u

That's interesting - thanks! I'll put that one on the list. The 152-0154-00 is used in a number of things, including the TU-5. The diode is 10mA/9pF, giving a switching speed of about 450ps, which

Well, I'd like to say that I had the answer to that, having compiled lists cross referencing TD's to Instruments to Specifications - but I draw a blank on that one. I *think* that a later version

Brilliant, Nice job, especially providing an index. If I ask really nicely can you crop the bottom of the pages so it all fills the full space? Cheers Robin In message <c3cd97+kveb@...>,

Hi, Gang I picked up a Tek 067-0554-00 tunnel diode pulser. (There's one for sale on eBay now, it you'd like to see a photo). It is a little box that goes between a 100 volt square wave generator
