ABSTRACT:
A system for measuring the bulk resistivity or sheet resistance of a sample of material includes a source of r.f. signals, a transmitting device and receiving device. The sample is placed between the transmitter and the receiver. A display is used to monitor the amplitude characteristic of the received r.f. signal at a particular frequency. The amplitude characteristic at the particular frequency is a measure of the bulk resistivity of the sample of the material.
