ABSTRACT:
Apparatus and method for measuring the radio signal (RF) transmission statistics of a communication channel. The apparatus is arranged to receive and process a wide bandwidth signal from which signal power is measured and from which fading or other such transmission problems can be measured for the wide bandwidth. In parallel with the wide bandwidth receiver there is a narrow bandwidth receiver arranged to receive the same RF signal but to process only a single tone or narrow bandwidth portion of the RF signal. From this narrow bandwidth processing the narrow bandwidth transmission statistical characteristics of the RF transmission channel can be measured simultaneously with the wide bandwidth statistical characteristics. The outputs of the spectrum analyzer are digitized and fed to a computer for storage and for other analysis.
