[Noisebridge-discuss] Fwd: RF probe

[Jake]

what are they making?  what frequency is it at?

I have a 900MHz FET probe for tektronix scopes, and i have a tek 485 scope 
that goes to about 500 MHz, and we have a spectrum analyzer here at 
noisenbrige that goes to 1300 MHz.

they can build an RF probe from a couple of 1N5711 diodes and a couple 
capacitors and a resistor.  But it depends what frequency you're dealing 
with.  It gets tricky at high frequencies and if you need accuracy it does 
make sense to get a proper probe like the one in the link.

Hey people,

Do we have one of these about?

Hey Kurtis,

Can you check with Range or hacker space, if they have an RF probe. I
am sure some RF lab, on campus, must
have this.

Something like:

I need this to test our board, to see at which point the RF signal breaks 
down.

Thanks :)
