For example, when setting ports 2 to 4, if you want to connect port 1 of the adapter to test
port 4 of the E5070B/E5071B and port 2 of the adapter to test port 2 of the
E5070B/E5071B, select RVS as the port connection mode.
When you select Adapter File, the comment contained in the adapter file is displayed at 4
in Figure 4-38.
NOTE
If the system Z0 written in the adapter file is different from the system Z0 of the
E5070B/E5071B, "file error" is displayed at 4 in Figure 4-38. In this case, you cannot set
the E5070B/E5071B to the adapter calibration mode.
Saving and loading calibration kit settings
You can save the selection of the calibration kit and standard for each test port (the setting
in the Reflection tab) and that for each pair of test ports (the setting in the Thru tab), as well
as load them for restoring whenever needed.

5. Performing Calibration
Set the E5070B/E5071B to the special calibration mode in which you can use a different
calibration kit for each test port (adapter calibration mode), then perform the calibration.
Step 1. Press

NOTE Do not terminate the VBA macro by force.
In the adapter calibration mode, if you terminate the VBA macro forcefully, for example,
with the
button, normal calibration can no longer be performed and the label of calibration kit 10
remains altered. To return to the normal calibration mode, restart the firmware of the
E5070B/E5071B. In this case, you cannot restore the label of calibration kit 10.
