In single port calibration, the calibration coefficients are measured by connecting the
OPEN, SHORT, and LOAD to the test port (Port 1). This calibration effectively
eliminates the frequency response reflection tracking error, directivity error, and
source match error from the test set in a reflection test using that port.
In S11 and DTF measurement, single port calibration is adopted.
Open
Performs the Open calibration measurement.
Short
Performs the Short calibration measurement.
Load
Performs the Load calibration measurement.
Abort
Aborts the current calibration measurement
Done
Saves the calibration coefficients.
Remarks:
The calibration is only valid for the S11 measurement item. When switching to S21 or
DTF, you need to recalibrate.
