Abstract : The report describes a cathode-follower impedance-matching device for use with piezoelectric gages. Six individual plug-in modules, one for each channel, are contained in a single chassis. Each module contains its own calibration voltage source. Power for operation is supplied by self-contained batteries. Control and calibration may be accomplished from the front panel or remotely by means of self-contained and self-powered relays. Input resistance is on the order of 470 megohms, and cable-terminating elements consisting of 450 ohms series resistance of 0.05 microfarad shunt capacitance are included. Although the system was designed for a specific field application, it should also prove useful in the laboratory. (Author)
