5. Setting Adapter Characterization
Step 1. Press
Setup
(3 in Figure 4-41). The Setup dialog box shown in Figure 4-42 appears.
Figure 4-42 Setup dialog box
Step 2. Make the setting of the calibration kit for the adapter that is connected to test port 1 of the
E5070B/E5071B in Cal Kit 1 (1 in Figure 4-42).
Step 3. Make the setting of the calibration kit for the adapter that is connected to test port 2 of the
E5070B/E5071B in Cal Kit 2 (2 in Figure 4-42).
When you calculate the S-parameters using measurement data in one direction only, you do
not have to make the setting in Cal Kit 2. In this case, check the box to the left of One-sided
measurement Only (6 in Figure 4-42).
Step 4. Enter the Delay of the adapter (3 in Figure 4-42) within an error of
1
4 f
×
----------
±
[s], where f is
the maximum measurement frequency [Hz]. For example, when the maximum value is 1
GHz, enter a value within an error of
±
250 ps.
Step 5. Enter a comment about the adapter (4 in Figure 4-42). The comment entered here is
displayed in the comment field in the Specify Cal Kit dialog box (4 in Figure 4-37).
Step 6. By default, the S-parameters are saved so that the port of the adapter connected to test port
1 of the E5070B/E5071B corresponds to port 1 of the 2-port Touchstone file. To save the
S-parameters in reverse order, which means that the port of the adapter connected to test
port 1 of the E5070B/E5071B corresponds to port 2 of the 2-port Touchstone file, check
the box to the left of Swap ports while saving (5 in Figure 4-42).
Step 7. Press
Close
(7 in Figure 4-42) to finish setting the adapter characterization.
