| http://www.w3.org/ns/prov#value | - It has been observed that at relatively high frequencies, such as 40 GHz or above, that the loading of a 20:1 probe (950 ohm tip resistor) tends to be dominated by the capacitance of the tip structure, which may be for example 10 fF (1/2PI/10 fF/40 GHz=400 ohms).
