4. Calibration
NOTE An asterisk (*) in the upper right of the softkey indicates that the existing calibration
coefficient will be cleared if you select the test port and execute acquisition of the
calibration coefficient (pressing Done).
Step 7. Make a THRU connection between the test ports (between the connectors to which the
DUT will be connected) selected in Step 6.
