Picosecond pulse labs used to sell NLTL's for pulse sharpening amonst other applications. NLTLs are still commercially available. Bruce

Reg, There might be a more elegant solution possible. The problem of battery ram was discussed at length in the pinball forums, and people made other solutions for it. Permanent ones. No battery to

To prevent that ground ring short, always practice safe probing; use a probe condom.? One of those plastic SMA connector caps works well, or just tape in a pinch.Jim Ford?Sent from my Verizon,

Nick, I have a 2246A that I had to get the ripple on the various DC busses knocked down. Replacing the ZS diodes was done, most of the secondary DC busses caps, a number of those were bad, I could not

I have one of Leo's 100 pS impulse units as a source for initial experiments. If I can narrow that to 10 -20 pS with discrete SMD parts I may be able to get the idea to work. There's a close

Nick, That is the way some of these threads go. You don't need a variac at this stage. A while ago you mentioned you had an isolation transformer, as I recommended and you asked whether to connect the

In my experience, the main transformer either works, or it doesn't... and yours works. Having an internal short to ground is what killed the few T2204's I know about. There are about 17 one amp ultra

It was suggested earlier this this thread that I should find 160-170VDC across C2202. I tested across R2256 as they appear to share the same connections, and got 156VDC. Next I checked for ripple

Chris, I think you refer here to the so-called "nose-to-nose" method of characterizing sampling scopes (Rush e.a.). Albert

Reginald, To obtain significant NLT compression, you need lots of stages, and a fast and big enough signal to start with - not easily done with conventional electronic and transmission line

OP here. Variacs weren’t mentioned until today so perhaps you are confusing me with another user. But you are correct that this is starting to feel overwhelming and I am losing confidence :( This is

Got it from the Telogy auctions years ago and have no use for it.? No part number, but comes with v.35 cable and internal ribbon cable.? Can provide photos to interested parties (please contact me

LOL With *great* difficulty. That's a large part of the appeal of the project. It's not very expensive and if I succeed serious bragging rights. It would be great fun to take to a Keysight trade show

I have a Danica SV03 which is an isolated 3A variable source with V & A meters, but when you look inside it is simply a standard variable transformer with a separate isolation transformer so wouldn't

There are variacs with an isolation transformer built in. But very rare. I own one made by Philips a dutch company.

All variacs that I know of are auto-tranformers, so no isolation. David

Hi Brian, I found your post very informative but wanted to keep things as simple and clear as possible for the OP. I had recommended a Variac and he wasn't sure what to do. In his case he can either
