RF Power meter signals must be precise and of good quality in order to replicate and measure the output of the equipment to be tested. Types of equipment that can be tested with the RF Power Meter include; cellular telephones, radar system equipment and communication base station transmitters. As technology continues to improve and new design methods are created, signals become more complicated. They are more complicated to test and precise power measurements are required. Todays Power Meters must be of good quality, be able to produce a variety of clear and precise frequencies, and offer a wide range of power.
