Personally for a one case, I would take normal coax,
pull the center conductor out,
and insert thinner resistance wire.
Should work for length of 1m or there about.
Not sure if that helps for your case.
It has been a loooong time; Tektronix made two high voltage probes -
one with a significantly higher voltage rating.
The one i have _did_ have the liquid inside but that has slowly
leaked out over the ages; it is the P6015 rated at 20KV, 40KV peak.
I think that is the top end in voltage.
Perhaps, but us mortals with a limited budget cannot order umpteen
thousand feet of coax with a resistive center.
The P6015 used ten feet of coax with resistive center (direct quote
from manual).
Cannot say what its resistance is..i read 657 ohms end-to-end on the
cable, and the schematic states 150 ohms 10% at probe end, implying the
coax center is about 500 ohms (~5 ohms per foot).
Since you specified 75 ohm cable, the R should then be 75 ohms
instead of 60 ohms (pickie).
Not any more. It has derated itself to about 12kV. It won't do 40kV
anymore without the fluorocarbon.
If you can get the 114 from somewhere, you can recharge it. See the manual.
It's not nice to needle people like that.
Do you think we should just leaf them alone?
Yew guys conifer control yourselves.
Don't be such a conehead.
That stems from our basic need for humor.
Sorry...mistype... cable is about 50 ohms per foot.Robert said:Perhaps, but us mortals with a limited budget cannot order umpteen

Resistance is about an order of magnitude higher than desired.Sjouke said:CUT

Reason why center conductors are virtually impossible to pull out,isSum said:Yeah, like dragging the center conductor out of a meter long piece of
coax is an easy task, much less feeding another back through.
Standard RG-8 center conductor dielectric strength is 1.5kV.and they
are not easy to get out. Fairly tightly bound to the core media.
Probably cheaper to find and get the right stuff.

Excellent!! You are on a roll!John said:It's not nice to needle people like that.
