Abstract
A test and/or measurement instrument includes at least three ports and at least three measurement circuits connected to the at least three ports, respectively. The test and/or measurement instrument further includes at least one signal generator circuit and a control circuit. The control circuit is configured to set a first calibration mode and carry out a first test of the instrument by measuring the calibration signal travelling from the signal generator circuit to the respective port as well as a signal traveling from the respective port to the signal generator circuit. The control circuit is configured to set a second calibration mode and carry out a second test of the instrument by measuring the calibration signal forwarded only to the main port in the first sub-mode and the calibration signal received by the respective port from the signal generator circuit via the main port in the first sub-mode.
