Calibrating for Increased Measurement Accuracy
Calibration Considerations
Fringe Capacitance
All open circuit terminations exhibit a phase shift over frequency due to fringe capacitance. Offset open
circuits have increased phase shift because the offset acts as a small length of transmission line. Refer to
