Anritsu Corp. has introduced a highly accurate power sensor that measures true-RMS power, regardless of the input signal or its bandwidth, over 63dB of dynamic range from 50MHz to 6GHz. MA24106A is suitable for measuring average power of CW, multi-tone and modulated RF waveforms such as those used in 3G, 4G and OFDM designs.

Anritsu says the MA24106A is a more cost-effective alternative to benchtop power meters because it easily communicates to a PC via a USB interface and it facilitates lab-quality measurements on the production floor for a fraction of the cost of traditional power meters. Sensor speed is optimized for best accuracy and noise performance, making it suitable for a variety of ATE applications.

The reference calibrator typically needed by power meters has been eliminated, which minimizes test station complexity and sensor handling as well as reduces test times. The standards used to calibrate the MA24106A are directly traceable to NIST. A high accuracy of 0.13dB typical is ensured because the calibration data is stored directly in the sensor, and all necessary frequency and temperature corrections are done internally, said Anritsu.

MA24106A offers 33dBm power handling and 3.3kV ESD protection, which make the sensor well suited for installation and maintenance of base stations, as well as for testing 3G and 4G products, cellphones and general-purpose RF devices.

Moreover, the MA24106A saves rack space because it is connected directly to a PC. Anritsu's power meter application software runs on Microsoft Windows and can be used to control and operate the sensor to provide the user with a familiar interface. It has advanced features such as average power vs. time display and data logging, plus a customizable offset table that enables flexible data capture and accurate measurements versus frequency. Its low current consumption of 100mA preserves laptop battery life in the field.

Starting list price is $2,400. Delivery is four weeks ARO.
