Step 1. Measure calibration data.
In this example, 3-port TRL/LRM calibration for test ports 1, 2, and 3 (1 in Figure A-8) is
performed by using the Match, Line 1, and Line 2 standards.

Step 2. Press the Thru button (2 in Figure A-8).
Step 3. Make the through condition for test ports 1 and 2 and press the [ ]Thru 1-2 button (1 in
Figure A-9). The through measurement is performed, and an asterisk appears at the [ ]Thru
1-2 button.
Step 4. Make the through condition for test ports 1 and 3, and press the [ ]Thru 1-3 button (2 in
Figure A-9). The through measurement is performed, and an asterisk appears at the [ ]Thru
1-3 button and then a check mark [v] (3 in Figure A-9) also appears on the Thru button.
