Parasitics Incident To Dut Connection - Keysight E4980A User Manual

Measurement Procedure and Examples

Parasitics Incident to DUT Connection

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

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.
