Simple transmission line question

If you put current into it, it will store energy too.

That's not fat. Similar to RG213, or LDF4-50.

Andrew make much fatter cables than that.

Just get LMR400. Not exactly the same...

It's much more wonderful than 'any other capacitor'. The fault scenario had a cable as part of the tuned resonator on a spark-gap, just like old-time radio transmitters; that was because a transmission line terminated with too-low impedance is an inductor. An open line is a transmission line terminated with two-high impedance, and (as stated) is a capacitor. But in all cases, there's a time constant in addition to the inductance or capacitance, which is what makes gizmos like Blumlein pulsers possible.

One cannot dismiss as 'negligible' either the inductance, or the capacitance, of a transmission line. If you do, the characteristic impedance loses both its parents.

And both of them have issues when and how tightly you bend them. There are also spiral dielectric (still about 2/3 to 3/4 air) coaxes available with intermediate velocity and bending properties.

Maybe, i have seen plenty of pulse generators that were current mode and thus had 50 ohm shunt termination.

Nice. I really like the transhybrid aspect.

Another cool transhybrid.

There was an old wire bonding machine sitting on the loading dock at Cincinnati Electronics to be sold as scrap. After one look at it, I could see why it was scrap. It looked like Noah had brought it over on his Ark.

They had used it to build hybrids, in house.

I suppose there might have been some hybridisation on Noah's Ark - pairs of every species might have gone in for foursomes. I hadn't realised that Noa h's Ark had made it to the USA, but I suppose that it's no less improbable than the story about it ending up 12,000 feet high on Mount Ararat, survivi ng a few volcanic eruptions in the intervening millenia.

I may know the ASU students who built it.

It was junked in the early '70s. Mendelson's, in Dayton, Ohio got all of their scrap.

I remember rummaging around a junk yard in San Jose in the late '70's and managing to build a working probe station, with 16 joy-stick probes, from 3 scrapped units. Paid about $700 for the three :-) ...Jim Thompson

From the looks of this junk, they had taken all the usable parts to fox another old machine and the only good part was the frame. You should have seen the clapped out NC PC drill. They could only do single boards instead of a stack, because the runout was so bad in the spindles. This was in an old Crosley/AVCO plant where a lot of equipment had been acquired as Air Force surplus. It is where Cartrivision was developed.
