The Anritsu MA24106A is a highly accurate, standalone USB power sensor designed to measure the true RMS average power of CW and modulated signals over a wide dynamic range of 63 dB. Operating from 50 MHz to 6 GHz, this sensor functions as a complete miniature power meter by incorporating internal microcontroller processing, analog-to-digital converters, and signal conditioning. It connects directly to a PC or compatible Anritsu handheld instruments, eliminating the need for a traditional external power meter benchtop unit.
