Frequency-selective measurements with a spectrum analyzer are the most obvious means to accurately measure the power of a communication signal. This paper presents an experimental investigation conducted to determine optimal settings for the frequency-selective measurements used for exposure assessments in the vicinity of a wideband code division multiacces (W-CDMA) mobile phone base station. Spectrum analyzers from three different manufactures are used in this work, i.e., one handheld and two bench top spectrum analyzers. They are directly connected to a base station simulator using a coaxial cable. Based on these spectrum analyzers, a known W-CDMA signal from the base station simulator has been measured for the different detector modes (root mean square (RMS) and positive-peak detectors) and different resolution bandwidths (RBW). We discuss the dependence of the standard deviation of the measured signal on spectrum analyzer types, detector modes and RBWs.
