Page 211 E4980A/AL: Do not use a test fixture. If the device does not have four-terminal pair measurement terminals, measure the device using a direct coupling test fixture (such as the Keysight 16047A/C/D/E). Step 3. On the CORRECTION page, enter the measured values obtained in step 2 as the REF A and REF B values with the function used in step 2.

Figure 7-17 shows parasitic impedance model after corrections are performed using the Keysight 16047A/D/E test fixture. In this case, to minimize the influence of parasitics on measurement values, insert the DUT completely into the test fixture while keeping the leads of the DUT as short as possible.
