The female-male THROUGH is only a connector, but not a calibration standard.
You have to connect the cable directly to Port 1.
However, the definition of the calibration standard in the calibration kit is decisive. By default, the length of a male-female THROUGH connection is defined to be zero, which supports the direct connection of the male-female connectors at the end of the test cables or test ports. Of course, the male-female adapter could be used, but this would make it necessary to enter its length in the calibration kit definitions. For most calibrations, however, the direct male-female connection is recommended because it avoids the use of an additional component and thus eliminates an additional potential error source. |
