Abstract
Real and imaginary components of microwave reflection coefficient are observed simultaneously with a response time of 1 μsec for use in paramagnetic resonance experiments. At a signal strength of one μW and an i.f. bandwidth of 3 MHz a change in reflection coefficient of 5×10−4 is detectable. When the experiment permits a larger signal strength or a narrower system bandwidth, increased sensitivity is available. Adjustment procedures that use a sliding short and a matched load are described.Keywords
