This chapter describes the setup and use of the model MA24105A Inline Peak Power Sensor for high accuracy power meter measurements.

The MA24105A is an in‑line type of power sensor module that can acquire forward and reverse measurements when connected to an Anritsu Handheld instrument with High Accuracy Power Meter (Option 19) installed. Forward measurements include Average Power, Crest Factor, Peak Envelope Power (PEP), Burst Average Power, and CCDF. Reverse measurements include Average Power, Reflection Coefficient, Return Loss, and VSWR. The frequency range is 350 MHz to 4000 MHz, and the power range is from 2 mW to 300 W, depending upon measurement function.

In the analog meter view, as shown in Figure: Forward and Reverse Average Power, forward measurements are displayed in the dial portion of the meter. The reverse measurement is displayed below the dial in a rectangular box. To view all of the forward and reverse measurements in table format, use the Summary display (as shown in Figure: Power Meter Summary Display). Figures showing measurement screens may differ from any actual screen on your instrument.
