N5ESE's Ballpoint RF Probe (1166 words)
Electrically, it's identical to the Classic RF Probe described elsewhere (where you can also find the theory discussion for this one).
Like the Classic RF Probe, this one is used in conjunction with a high-impedance-input Voltmeter or Digital Voltmeter (DVM).
She has the ground clip connected to a convenient place in the circuit's ground, and the probe touches the test point we want to measure.
FlashWebHost.com - Makinging RF Probes. (301 words)
An RF probe is used to directly measure the level of RF voltage present at a particular point and is one of the most useful test instrument in the hands of the home brewer.
It is normally used with a digital multi meter to indicate the voltage level as dc voltage which is equivalent to the RMS value of the RF voltage being measured.
The design of the RF probe is a function of the DC input resistance of the meter we intend to use with it.
