The MA24218A power sensor is designed to provide fast, accurate average power measurements from 10 MHz to 18 GHz over 80 dB of dynamic range. The sensor employs a patented "triple path" architecture that provides True-RMS measurements (similar to thermal sensors) over the entire frequency and dynamic range, enabling users to make highly accurate average power measurements for CW, multi-tone, and digitally modulated signal up to 18 GHz.The sensor employs high-performance digital processing that enables best-in-class measurements speeds, including >1,600 continuous power readings/s continuous and >11,000 buffered readings/s.

A unique, low noise design eliminates the need to zero the sensor before taking measurements for most applications.

The sensors have internal and external triggering capability that facilitates individual slot power measurements of TDMA waveforms as well as burst power measurements of periodic and non-periodic waveforms.

The sensor can be controlled with a PC via remote programming commands or with PowerXpert, a free of charge software application. These sensors are also compatible with most Anritsu RF and microwave handheld instruments. The high accuracy power meter software option (e.g., Option 19) may be required.

The best-in-class damage protection combined with the silicone protective covering give the sensor increased ruggedness and enable users to protect their investment.

*1 Expanded uncertainty with K=2 for CW measurements after zero operation. Includes calibration factor and linearity over temperature uncertainties, but not the effects of mismatch, zero set and drift, or noise. Specifications apply over a temperature range of 0 °C 50 °C and a 60 minute warm up period.
