    摘要: A power sensor for measuring the average power of modulated or non-modulated high-frequency or microwave signals across a wide dynamic range is disclosed, in which a combination of the following features are used: a) the signal power to be measured is delivered to a first sensor branch for measuring said signal power in a lower power measuring range (−70 to −16 dBm), b) the sensor branch has several spatially separate measuring points on a connecting line between the input and a power splitter connected downstream; and, c) at the same time, the signal power to be measured is delivered to at least two other sensor branches by means of the power splitter with a largely load-independent synchronous output, via attenuators, in order to measure the signal power in at least two other power measuring ranges (−22 to +4 dBm or −2 to +20 dBm).
