Anritsu MA24104A

The MA24104A Inline High Power sensor is designed to provide accurate average power measurements from 600 MHz to 4 GHz for power levels as low as 2 mW to as high as 150 W. The sensor employs a single directional coupler at the front end of a diode sensor with "dual path" architecture that provides (similar to thermal sensor) True-RMS measurements over the entire frequency and dynamic range enabling users to make highly accurate average power measurements for both CW, multi-tone and digitally modulated signals such as GSM/EDGE, CDMA/EV-DO,WCDMA/HSDPA, WiMAX, and TD-SCDMA. The presence of a micro-controller along with signal conditioning circuitry, ADC, and power supply in the sensor makes it a complete miniature power meter.
