Abstract:
1. A signal measurement system adapted for use with an electromagnetic receiver or transceiver system, comprising: a case; an electromagnetic (EM) receiver or transceiver system contained within the case adapted to receive at least one calibrated EM signal from at least one reference EM source, wherein said EM receiver or transceiver system contains and to perform signal processing on said calibrated EM signals; an at least one system antenna having an output coupled connected to said EM receiver or transceiver system's input circuitry adapted to have a first antenna pattern field; at least one signal measurement probe contained within the case, said at least one signal measurement probe is also coupled to a point within a signal path in said EM receiver or transceiver system and is adapted so as to minimize altering the at least one system antenna's first antenna field and the system's receiver performance, wherein said at least one signal measurement probe is adapted to sample output signals from said point within said signal path and produce antenna pattern measurement outputs comprising a system antenna pattern field or link budget measurements; and an output section adapted to send said antenna pattern measurement outputs to a remote location away from said receiver or transceiver for recording and analysis using a non-electrically conductive medium or a different EM spectrum than is received by said at least one system antenna.
