10MHz to 3GHz frequency range. -40 to +5 dBm dynamic range, true RMS measurements at 45 dB dynamic range. Performs full frequency range, dynamic range calibration using Agilent instruments before leaving the factory, with all 576 calibration points calibrated at 100MHz intervals (10MHz and 50MHz for calibration points below 100MHz) at 2.5dBm intervals. Manual selection of test frequency (calibration factor) to improve overall accuracy. Four selectable sampling rates of 10/40/640/1280Hz. Synopsis: The Upper Unit RF Power Meter is designed to provide near benchtop instrument accuracy for portable RF power testing in the field, providing you with a practical power sensor solution for use in graphic and digital transmission, communication base stations, power amplifiers, etc. The RPM3GS 0.01-3GHz RF Power Meter provides a dynamic range of -40-+5dBm, enabling users to make accurate measurements of CW and digitally modulated signals. The sensor connects to the RF Power Meter host computer software via a USB port. Offset compensation function to manually compensate for external attenuators. Connects to a computer via USB Type-C port, no additional power supply required.
