Abstract :
A Measurement system for very week radiation such as from Ultra Wide Band(UWB) devices or ZigBee, PLC, and so on. This system covers from 0.8GHz to nearly 30GHz with three individual receivers with 32MHz or 512MHz I/Q IF output to 8bit samplers, K5/VSSP32 or ADS3000+, controlled by PC. Receivers are equipped two Dicke switches operated by the PC, one for dummy load in room temperature and another for noise diode for gain calibration in signal integration time, which are aimed for so weak level of noise as -90dBm/MHz.
