RF Digital Wattmeter Basics

RF wattmeters are devices that measure power (watts) into a circuit or system such as a transmission tower. Bi-directional wattmeters allow the user to take data on a system while it is operating. In addition to delivered power, they also measure reflected power.

Understanding Antenna Gain

Antenna gain indicates how strong a signal an antenna can send or receive in a specified direction. Gain is calculated by comparing the measured power transmitted or received by the antenna in a specific direction to the power transmitted or received by a hypothetical ideal antenna in the same situation.

RF Analog Wattmeter Basics

Wattmeters are used in a variety of electrical circuit measurement and debugging applications. For example, they can check the power consumption of electrical appliances. RF wattmeters are devices that measures power (watts) into a circuit or system such as a transmission tower.
