Using S-Parameters with R&S®NRP-Z Power Sensors

Using S-parameters instead of a fixed offset makes measurements more accurate by accounting for the interaction between the sensor and a component. This shifts the sensor's reference plane from the sensor's RF connector to the input of the device that is being applied externally. This application note explains the fundamentals of using S-parameters and discusses some common applications in which S-parameter correction is useful. It also introduces a command line tool for updating S-parameter data in custom applications or in automated test setups.
