Abstract
A tester including a source and measuring device and a TX port connected to the source and measuring device is configured to determine a source reflection coefficient using an extension circuit. The extension circuit includes a calibration device having a power sensor. The calibration device is configured to provide a plurality of different terminations at the TX port. The tester is configured to calibrate a source power of the source and measuring device using the determined source reflection coefficient and the power sensor.
