DIY active probe construction

[gnihgnahgnap]

Hello,

I was looking for information on the DIY construction of probes. I already
noticed another thread on this board that listed this url:

https://emcesd.com/1ghzprob.htm

Good stuff
Now, while 1 GHz passive is very nice, does anyone know of any sites that
explain the construcion of say an active 2.5 GHz probe? Yes, I know that's
more complicated. But on the other hand, that's all part of the fun, eh
It's a hobby thing.

thanks,
gnih, gnah, Gnap!
