The Anritsu MA24105A Inline Peak Power Sensor is designed to take accurate average power measurements over 2 mW to 150 W, from 350 MHz to 4 GHz. The sensor employs a "dual path" architecture that provides accurate bidirectional measurements and eliminates the need for additional low-level power sensors.
The MA24105A Inline Peak Power Sensor provides highly accurate average and peak power measurements for RF applications. It operates from 350 MHz to 4 GHz, supports True‑RMS measurements from 2 mW up to 150 W (300 W pulse), and offers forward and reverse power, reflection, SWR and crest‑factor calculations in a single inline unit.
The sensor connects via USB 2.0 to a PC running PowerXpert software or directly to compatible Anritsu handheld instruments such as Site Master, Spectrum Master, Cell Master, BTS Master, VNA Master and Economy Benchtop Spectrum Analyzers. Optional USB‑to‑LAN converters enable remote monitoring, and the device meets environmental and safety standards for field and production use.
