New, simpler, and mNEW METHODS FOR MEASURING SPURIOUS EMISSIONS. Quarterly progress rept. no. 1, by J. Goldberg, O. Hinckelmann and others. Aug 61, 73p. incl. illus. tables, 10 refs. Rept. no. 1112-I-1 Contract AF 306022511, Proj. 1112 RADC TDR 62-97Unclassified report DESCRIPTORS Microwaves, Radio transmit ters, Measurement, Dipole antennas, Circuits, Electric fields, Waveguides, Transmission lines, Microwave networks. ore accurate methods of measuring the spurious-emission power of microwave transmitters are being investigated. Two of the methods--movable-probe and fixed-probe-measure tllus. tables, 10 refs.

In all of the methods, the probes are connected to circuits that frequency-filter, detect, and sum the amplitudes of the voltages induced on the probes at various points in the electric fields and indicate the spurious po er of the transmitter at the frequencies of interest.
