Anritsu have introduced the MA24104A inline high power sensor that can conduct accurate measurements on the transmitter output power of wireless base stations.
The MA24104A inline high power sensor employs a unidirectional coupler at the front end of a diode sensor with dual path architecture that provides True-RMS measurements over a broad frequency range of 600MHz to 4GHz and a dynamic range of 2mW to 150W (+3dBm to +51.76dBm), allowing users to conduct average power measurements on CW, multi-tone and digitally modulated signals during base station installation, maintenance and troubleshooting.
Precise average power measurements of high power signals up to 150W (~52dBm) are achieved as a result of the sensor design, which stores calibration data directly in the sensor, enabling the necessary corrections, such as frequency and temperature to be done inside the microprocessor of the sensor. The return loss and directivity of the instrument are optimised to maintain high accuracy. All standards used to calibrate the MA24104A inline high power sensor are directly traceable to NIST.
The MA24104A inline high power sensor has a good match of >29dB and a low insertion loss of <0.2dB, making it suitable for continuous power monitoring of transmitter systems and antenna. A data logging function in the Anritsu power meter software application allows users to record measured power overtime data on external media, so that long-term drift measurement analysis, environmental testing and trend analysis can be conducted.
The MA24104A inline high power sensor adds high power inline measurement capability to Anritsu’s handheld analysers, including the Site Master, BTS Master, Cell Master, Spectrum Master and VNA Master. It is compatible with the MS271xB Economy Microwave spectrum analysers and can be used as a standalone test solution when connected to a Windows-based PC. The MA24104A inline high power sensor operates using USB power, external wall adapter or AA batteries when RS232 is used to connect it to a Site Master or Cell Master analyser.
