Make a thru connection between test ports x and y (between the connectors to which the
DUT is connected) selected in Step 6.
Step 9.
Press
Port x-y Thru

x
and

are the thru-connected port numbers) to start the
re-measurement of the calibration standard.

Overwrite
to finish the re-calibration for the full 2-port calibration.At this point, the
calibration coefficients are re-calculated and saved.
Improving accuracy of measurement using partial overwrite (thru
calibration) along with ECal
Inaccuracy caused by the ECal thru calibration standard can be reduced by performing thru
measurement with the calibration kit and partial overwrite after the execution of full N-port
calibration with ECal.
For example, follow these steps for full 2-port calibration.
Step 1.
Execute full 2-port calibration according to the procedure of “Full 3-Port and Full 4-Port
Calibration using 2-Port ECal” on page 132 and save the calibration coefficients.
Step 2.
Execute steps from Step 2 to Step 11 of “Partial overwrite” with the thru standard of the
calibration kit.
