Abstract : A study was made leading to a design plan for accessory equipment to be used with radio interference measuring sets and signal generators. The frequency range of interest is 0.014 to 40,000 Mc. Two items of equipment were investigated: a receiver input coupler and an audio susceptibility tester. Consolidation of as many of the various test setups for performing the various measurements into as few basic setups as possible is considered. Some differences applying to waveguide systems are noted. Work on a thin dummy load in a coaxial configuration was started. A taper section for this load was electroformed. Work on the audio susceptibility tester continued with consideration given to both the amplifier and transformer. A receiver input coupler was constructed and preliminary results are shown. A discussion of the various techniques presented in the literature for the measurement of spurious and harmonic emissions in waveguide systems is presented. A method for determining the maximum VSWR that can be expected from the connection of a group of components with given VSWR's is described. (Author)
