Calibration
OPEN/SHORT Response Calibration (reflection test)
Step 4. Select OPEN or SHORT response calibration.
Softkey Function
Response (Open) Displays softkeys for performing an OPEN response calibration
(response calibration with an OPEN standard)
Response (Short) Displays softkeys for performing a SHORT response calibration
(response calibration with a SHORT standard)
Step 5. Press Select Port.
Step 6. Select the test port upon which you will perform OPEN/SHORT response calibration.
Softkey Function
1 Selects port 1
2 Selects port 2
3 Selects port 3
4 Selects port 4
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 the acquisition of the
calibration coefficient (pressing Done).
Step 7. Depending on the selection made in Step 4, connect an OPEN or SHORT calibration
standard to the test port (connector to which the DUT is to be connected) selected in Step 6.
