In-Line Peak Power Sensor: MA24105A

The Anritsu MA24105A Inline Peak Power Sensor is designed to take accurate average power measurements from 2 mW to 150 W and peak power measurements from 2 W  to 300 W over the frequency range of  350 MHz to 4 GHz. The sensor employs a “dual path” architecture that enables True-RMS measurements over the entire frequency and dynamic range allowing users to measure CW, multi-tone and digitally modulated signals such as LTE, LTE-TDD, GSM/EDGE, CDMA, W-CDMA, WiMAX, TD-SCDMA, WLAN, and LTE. The forward direction path also include a 4 MHz bandwidth channel that has peak and comparator/integrator circuits that add measurement functions such as PEP power, crest factor, CCDF, and burst average power. Another detection circuit on the reverse direction adds reverse power measurement capabilities including reverse power, reflection coefficient (magnitude), return-loss, and SWR. The presence of a micro-controller along with signal conditioning circuitry, ADC, and power supply in the sensor makes it a complete miniature power meter.

These highly accurate, standalone instruments communicate with a PC via USB or with many of the Anritsu handheld products (often requiring Option 19). The USB sensor comes standard with application software (PowerXpert™) for use with PC that mimics the user interface of a power meter.
