Anritsu MA24126A – Microwave USB Power Sensor

The Anritsu MA24126A is a microwave USB power sensor engineered for precise average power measurements spanning 10 MHz to 26 GHz. It delivers True-RMS measurements across a 60 dB dynamic range, with accuracy comparable to thermal sensors for CW, multi-tone, and digitally modulated signals. The dual-path architecture maintains measurement linearity <3% across the full frequency and power range, supported by NIST-traceable calibration. Connection via USB to a PC enables operation through the free PowerXpert™ software or optional High-Accuracy Power Meter software, making it suitable for aerospace, defense, satellite, and cellular applications.
