Abstract: Kits for assembling rackable gates are provided. The kits comprise a pair of gate uprights, each gate upright comprising a tubular elongate member and a bracket. The tubular elongate member comprises apertures configured to accept a fence panel rail therethrough and into an elongate channel situated on an interior surface therein and configured to securely receive an end of the fence panel rail such that lateral and torsional movement of said fence panel rail is restricted. The bracket comprises a pair of bracket arms attached to an exterior surface of the tubular elongate member, each situated directly opposite the other with an aperture situated therebetween and configured to accommodate a fastener for fastening a fence panel rail thereto. Also provided are methods for assembling gates from such kits and gates assembled from such kits and by such methods.

Abstract: A time-domain baseband measurement method measures modulated microwave signals typically used in communication systems by converting microwave signals to baseband before measurement for improved accuracy compared to direct measurement at the microwave frequency. A downconverting receiver is first characterized using a prior characterization method and then the modulated microwave signal is applied to the downconverting receiver and the response of the downconverting receiver is removed to provide an accurate characterization of the modulated microwave signal. Such an accurate measurement of the modulated microwave signal can be used for communications system performance verification as well as for characterizing communications devices and systems. One particular application is the measurement of input/output characteristics of nonlinear power amplifiers using such modulated microwave signals.

Abstract: A three-pair measurement method determines the amplitude and phase transmission response of frequency translating devices including a device under test and two test devices using a vector network analyzer and a controller where one of the devices has reciprocal frequency response characteristics. The characterization of single sideband and double sideband devices such as mixers, is preferably performed by combining data from analyzer two-port swept measurements. The measurement method provides a low-pass equivalent transmission response of the devices.
