The Keysight (formerly Agilent) U2002A is a high-performance USB average power sensor covering a frequency range from 50 MHz to 24 GHz and a wide dynamic range from -60 to +20 dBm. Operating as a standalone test instrument without the need for a separate power meter, it connects directly to a PC or compatible Keysight instrument via USB. The sensor features an internal triggering mechanism and provides fast measurement speeds and excellent SWR performance, making it highly suitable for RF and microwave power measurements in manufacturing, R&D, and field service.
