RF power meters measure the strength of an RF signal in dBm or watts and may also be called an RF Wattmeter. Typically RF power meters are used to measure the output of a transmitter. An RF Power meter makes measurements of RF power from a transmitting device. Different meters work at different frequency ranges and different power levels. Different measurement methods may also be used depending on the meter. For more information on power meters, visit the power meters information page on GlobalSpec.
