Abstract
An electron spin resonance spectrometer comprises a resonator arranged in a magnetic field of constant strength and high homogeneity and containing a sample. The resonator can be supplied, via a microwave bridge, with microwave energy in the form of a continuous-wave signal (CW) or in the form of an intermittent signal (P). Measuring signals emitted by the resonator can be supplied to a detector arrangement and a signal evaluation arrangement. In order to be able to carry out individual experiments with continuous-wave signals or intermittent signals of low power or with intermittent signals of high power in arbitrary combination and with an arbitrary succession of microwave pulses, the spectrometer comprises a first channel for supplying a continuous-wave signal or an intermittent signal of small power in the mW range and a second channel for supplying an intermittent signal of high power in the W range. The channels are connected by their inputs to a common microwave source and united at their outputs. So the said channels can be selectively operated either individually or jointly.
