[PVRCNC] Question: RF probe

[Kent Winrich]

The best way is with a spectrum analyzer and sweep the circuit.
(Y'all have sweeping Spectrum Analyzers and Network
analyzers....right??? LOL)

I would say if you are working with filters, it may be suspect, as you
dont know what is going on.  And at what is going on at what
frequency.

I would try an RF amp meter.  You ****MAY**** get a little more accurate.

My 1.5 cents worth.
