Abstract

Embodiments of the present invention provide a radio frequency power time domain measurement method and a calibration method. The radio frequency power time domain measurement method includes: placing a power probe and a microstrip line of a board under test opposite to each other, so that the power probe is located above the microstrip line of the board under test And perpendicular to the microstrip line of the board under test, and the center of the power probe coil is projected on the microstrip line of the board under test; connect the power probe and the oscilloscope to the first channel and the second channel of the oscilloscope through transmission lines that meet the test requirements; When a measurement signal that meets the test requirements is input to the microstrip line of the board under test, the oscilloscope collects the power output signal of the power probe; the computer obtains the RF power of the board under test according to the power output signal of the power probe. This non-contact measurement method can perform time domain measurement of RF power without modifying or stopping the system, which is convenient for testing.

Description

technical field [0001] The invention relates to the technical field of radio frequency power frequency domain measurement, in particular to a radio frequency power time domain measurement method and calibration method. Background technique [0002] Power time-domain measurement refers to measuring the change data of power parameters with time. At present, the contact measurement system is mostly used for power time domain measurement, but the inventor found that the traditional technology has at least the following defects during the implementation process: the traditional test system needs to directly contact the measured point, so it should be fully considered not to interfere with the measured point system, it is often necessary to modify the system or stop the system for power time domain testing, which is inconvenient to test. With the increasing complexity of the test object, it is hoped that the time-domain measurement of RF power can be performed without modifying t...
