For details about aperture step width, refer to descriptions in "Aperture Step
Width" for S11.
Align
In S21 measurement, the calibration coefficients are measured by connecting the
Through to the two test ports. This calibration effectively eliminates the transmission
tracking error resulting from the transmission test set using that port.
Through
Performs the Through calibration measurement.
Abort
Aborts the current calibration measurement
Done
Saves the calibration coefficients.
Remarks:
The calibration is only valid for the S21 measurement item. When switching to S11 or
DTF, you need to recalibrate.
Clear
Clears the saved calibration coefficients.
Port Extension
Extends the calibrated plane by setting the delay and loss of the test signal resulting
from the electrical length and compensation fixture of the connector. In this way, you
do not need to perform extra calibration any more.
Port Extension
Enables or disables the port extension function.
