Radio frequency (RF) power meters are calibrated broad band measurement devices. The radio frequency power can be displayed in watts or dBm (decibel-milliwatts). Applications are boundless, RF power meters are an important tool for testing any microwave device. There are many applications involving power measurement including manufacturing test of consumer, industrial and military communications equipment. The applications can have a substantial variation in modulation and power level. When choosing a USB power sensor, you must consider factors such as frequency and dynamic range to fit your requirement. This post discusses the factors you should consider to be able to select the right RF power meters based on your application.
