MA24104A power sensor

From Anritsu Co. comes the MA24104A inline high power sensor that can conduct highly accurate measurements on the transmitter output power of wireless base stations.

The 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 best-in-class 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 very high power signals to 150W (~52dBm) are assured due to the sensor design, which stores all calibration data directly in the sensor so all necessary corrections, such as frequency and temperature, are done inside the microprocessor of the sensor. Also, the return loss and directivity of the instrument are optimized to maintain high accuracy. All standards used to calibrate the sensor are directly traceable to NIST.

The MA24104A has a good match of >29dB and low insertion loss of Versatile, the MA24104A adds high power inline measurement capability to Anritsu's handheld analyzers, including the Site Master, BTS Master, Cell Master, Spectrum Master and VNA Master. It also is compatible with the MS271xB Economy Microwave Spectrum Analyzers, and can be used as a standalone test solution when connected to a Windows-based PC. The MA24104A operates using USB power, external wall adapter, or AA batteries when RS232 is used to connect it to a Site Master or Cell Master analyzer.

Field technicians can use the MA24104A with a Site Master or BTS Master analyzer to verify base station transmitter output power without the need for a bulky attenuator. LAN connections can be established for remote monitoring of output power. Its high performance also allows the MA24104A to be a cost-effective alternative in production environments. Base station manufacturers and high-power component suppliers can conduct power measurements on amplifiers, couplers, diplexers, and antennas during manufacturing with the MA24104A.

Delivery is two to four weeks ARO.
