Oh, forgot to mention. I did use the scope again quite recently, to actually *measure* the velocity factor for some RG-59 coaxial cable.

I'm making coax-loop baluns for some TV antennas, and it's very important to know how fast signals pass through the coax.

The nice thing about a scope this quick (1gs/sec) is that it only takes a few metres of coax to have sufficient delay that it can be measured on the scope!

The coax I had on hand here measured as a VF of 0.80c, which is quite close to the oft posted ballpark figures for RG-59 on the web (which range around 0.78 to 0.82 or so), for foam-core stuff.

Cheers
