Measurement Procedure and Examples
Parasitics Incident to DUT Connection
7-
Parasitics Incident to DUT Connection
Bear in mind that some parasitics remain in the measurement path even after
performing corrections, as shown below.
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.
