RF Power Basics
Understanding what RF power measurements tell you.
The basics
An RF wattmeter helps characterize power in a radio-frequency system. How a measurement should be interpreted depends on the signal, measurement method and instrument capabilities.
What to keep in mind
A power indication is useful only in context. Consider the frequency and signal type, confirm the instrument is suitable for the application, and consult its documentation for accuracy and safe operating limits.
