Anritsu MA24340A – Microwave CW USB Power Sensor

The Anritsu MA24340A is a microwave continuous wave (CW) USB power sensor engineered for accurate RF and microwave power measurements across field, manufacturing, and laboratory environments. Operating from 10 MHz to 40 GHz with a 90 dB dynamic range, this compact sensor delivers measurement speeds exceeding 2,100 readings/s in continuous mode and 5,600 readings/s in buffered operation. The K(m) connector interface and direct USB connectivity to PC or laptop streamline data acquisition and enable real-time analysis via PowerXpert™ software or remote programming commands.
