STEP 4. Calibration
Calibration is performed by using the 7-mm terminal of the test head as the calibration
reference plane (Figure 5-4). Unlike impedance measurement, fixture compensation after
calibration requires only SHORT compensation (see Table 5-3).

points for calibration/fixture compensation data," on page 61.
Step 4. Connect the 0 S (OPEN) standard to the 7-mm terminal of the test head (see Figure 3-31 on
page 62).
