We describe the design and procedures for use of a simple experimental platform that enables the measurement of the electric permittivity and magnetic permeability of samples over the frequency range of 1 MHz to 3 GHz and at temperatures between 300 to 4.2 K. The platform makes use of an economically designed experimental cryogenic probe capable of utilizing interchangeable probe heads for separate measurements of electric permittivity and magnetic permeability. The system is designed for general use by researchers carrying out research and development and science and technology efforts at SPAWAR Systems Center Pacific SSC Pacific that involve the use of materials in radio-frequency responsive applications.
