Anritsu MA24118A – Microwave USB Power Sensor

The Anritsu MA24118A is a microwave USB power sensor engineered for accurate average power measurements across microwave frequencies. It delivers True-RMS measurements for CW, multi-tone, and digitally modulated signals, with dual-path architecture supporting both internal and external triggering for precise TDMA and burst power analysis. The sensor connects via USB to a PC running PowerXpert software or integrates directly with select Anritsu handheld instruments for field-based measurements.
