Execution Procedure Of Characterization For Test Fixture Using Probe - Agilent Technologies ENA Series User Manual

Execution procedure of characterization for test fixture using probe

The adapter characterization function also lets you obtain the characteristics of a test
fixture that is inserted between the instrument and a DUT that cannot be connected directly
to the instrument. In this case, a probe is used, and the obtained characteristics are saved to
a 2-port Touchstone file. The obtained result can be eliminated by using the network
de-embedding of the fixture simulator function, which permits measurement by
eliminating the effect of the test fixture.
NOTE For more information on test fixture characterization using a probe, see Product Note
E5070/71-4.
1. Setting Stimulus Conditions
Set the stimulus condition of the channel for which you will execute the test fixture
characterization.
2. Performing Calibration
Perform 1-port calibration for the probe in the channel for which the stimulus condition has
been set.
3. Starting VBA Macro
Start the VBA macro to display the Adapter Characterization screen (Figure 4-41).
4. Selecting Channel
Select the channel for which calibration has been performed (2 in Figure 4-41).
5. Setting Characterization
Step 1. Press
Step 2. Make the setting of the calibration kit used in Cal Kit 1 (1 in Figure 4-42).
Step 3. Enter the Delay of the test fixture (3 in Figure 4-42).
Step 4. Enter a comment about the test fixture (4 in Figure 4-42). This comment is added to the
comment line at the beginning of the Touchstone file.
Step 5. Check the box to the left of Swap ports while saving (5 in Figure 4-42) to align the
direction when specifying a file in the network de-embedding function.
Step 6. Check the box to the left of One-sided measurement Only (6 in Figure 4-42).
Step 7. Press
