Abstract
The inherent sensitivity of an rf measuring system and the effect of the system transmission characteristics on the detectability of the rf source noise are examined. The results are applied to resonant reflection and transmission systems and to a nonresonant transmission system. The conventional reflection cavity paramagnetic resonance system is discussed in detail, and the conclusion is that this configuration will be source noise limited at power levels above 1 mW. Unconventional configurations, such as a dual mode induction cavity or a dual cavity transmission system, would have to be used to achieve higher sensitivity.Keywords
