Overview
This chapter provides an overview of power meter measurements and how to set up the instrument to use an external USB Sensor in the High Accuracy Power Meter mode. Actual power is measured at the USB sensor connector in dBm and Watts or relative power in dB and percentage. The frequency span and dynamic range for measurements is determined by the USB external sensor.
Note 
Check the graph title in the top right of the display to confirm that the instrument is in High Accuracy Power Meter mode. If necessary, press the Menu key to change modes.
In this mode and with an appropriate sensor, the instrument can be used to make high accuracy power measurements including true RMS measurements for both CW and complex digitally modulated signals.
A general overview of USB sensors including connection and measurements setup beginsIntroduction.
With the MA24105A in-line sensor, additional functions are available including: forward and reverse measurements.
Forward Measurements: Average Power, Crest Factor, Burst Average Power, Peak Envelope Power (PEP), and CCDF.
Reverse Measurements: Average Power, Reflection Coefficient, Return Loss, and VSWR.
Refer to MA24105A Inline Power Sensor for information specific to this in-line sensor.
Note 
Sensors are not included with the Site Master and must be purchased separately. The S331L Site Master data sheet lists compatible sensors.
