As an overview, the PSN50 sensor provides true RMS measurements from -30 dBm to +20 dBm over the frequency range 50 MHz to 6 GHz enabling users to make highly accurate power measurements for both CW and digitally modulated signals such as GSM/EDGE, CDMA/EV-DO,WCDMA/HSDPA, WiMAX, and TD-SCDMA. Accurate power measurements in the field are important for verifying that transmitter outputs are operating at specified levels. For example, service technicians need to verify base station output power because lower output power can quickly translate into large coverage differences that can cause dropped calls.

It is a highly accurate instrument that communicates with many of the Anritsu handheld products (often requiring Option 19) through USB or RS-232 serial interface. In contrast, the instruments with an RS-232 serial interface require an external DC supply in addition to the RS-232 serial cable.
