Abstract: A radio frequency power generation and power measurement system includes power sensors to measure both the radio frequency (RF) power transmitted by radio equipment under test, and the RF power received by the radio equipment under test. Power sensors are mounted in a separate assembly remote from the main power measurement and generation. The RF power sensors and other components in the remote assembly are interconnected to allow measurement of both received and transmitted RF power at the RF connector or connectors of the radio equipment under test. The main assembly and the remote assembly are connected by a flexible link.

Abstract: An unknown RF power is converted to a voltage by a detector (11). The voltage is converted to a number by a digitiser (12). A separate and fixed RF power reference (14) drives a second detector (15), whose voltage output is also converted to a number by the digitiser (12). The RF detectors are thermally coupled. Temperature variations in the RF power to voltage characteristic of the detector (11) are corrected by measuring the RF power reference (14) via the detector (15).
