RF test equipment generates test signals or analyzes transmitted signals from RF components or RF equipment. Typically, RF testing equipment is used in conjunction with RF transmitters, electronic devices that create continuously varying electric current, encode sine waves, and broadcast radio waves. Modulation techniques are used to encode the sign wives for subsequent broadcast as radio signals. There are several basic modulation methods. Examples include amplitude modulation (AM), frequency modulation (FM), and on-off key (OOK). To verify the success of a modulation technique, RF test equipment is used to analyze the quality of the transmitted radio signal.
There are many different types of RF testing equipment. Most RF test equipment incorporates one or more RF meters. Examples of RF meters include RF power meters, RF field strength meters, and RF volt meters. An RF power meter measures the power of the transmitted RF signal, normally within a range of 10 kHz to 40 GHz. Hertz (Hz) is a measurement of frequency in cycles per second. Gigahertz (GHz) is a unit of frequency equal to one billion cycles per second. An RF field strength meter measures the strength of the transmitted electromagnetic wave, usually at frequency between 1 MHz and 14 GHz. Megahertz (MHz) is equal to one million Hertz (Hz). An RF volt meter is used to test voltage signals ranging from 200 uV to 300 V, and with RF test equipment operating between 10 kHz to 1.2 GHz. A volt (V) is the electrical potential difference between two points in a circuit. Kilohertz (kHz) is a unit of frequency equal to 1,000 Hz.

RF test equipment is used in a variety of applications and industries. Some RF test systems are used with integrated circuits (ICs) that incorporate surface mount technology (SMT), through-hole technology (THT), or flat pack (FPAK) packaging. Other RF testing equipment is used to test cell phones or telecommunications equipment. Portable RF test equipment may include an RF power meter, RF field strength meter, or RF volt meter.
