Abstract :
The following are described: Power measurements using the torque vane wattmeter, Hall effect, thermistor and bolometer, and calorimetry (vaporization of liquid gases); attenuation measurements using rotary attenuators, cut-off attenuators, resistive film attenuators; general considerations of accuracy of measurement of attenuation; impedance measurements using directional couplers, swept-frequency reflectometers, slotted waveguide standing wave meters, `three probe line¿ method, substitution methods; frequency measurements using resonant cavities; echo boxes for assessment of radar performance; noise source measurements; particle accelerator measurements using perturbation techniques; dielectric loss measurements; mechanical construction aspects including materials used, and choke coupling. A select bibliography of thirteen relevant papers published in the Brit.I.R.E Journal is appended and numerous other references are given.
