BOLOVAC systems for measuring electrical quantities from 0.5 MHz through microwaves
Myron C. Selby · 1972
A novel device-the BOLOVAC-is employed in measurement systems that furnish known voltages and currents up to 18 GHz, remove serious difficulties in power measurements, and are applicable in impedance, attenuation and other measurements.Typical of such measurements are the evaluation of rf power sources; calibration of power meters; measurement of net and incident power flow in a system; calibration of signal generators, voltmeters, current meters, picosecond-rise-time pulse-display oscilloscopes, spectrum analyzers; determination of insertion loss of components; and calibration of directional couplers.The Bolovac also serves as an accurately known resistive termination for match or mismatch applications from LF through microwaves.
