Open Circuit Terminations

Specifications and Available Models

All Maury open circuits are provided with generic, fourth order polynomial capacitance coefficients suitable for entry into
Agilent, Anritsu and other network analyzers. Note that the 8585 and 8883 series opens are for use in 75 ohm calibrations
only. These units should never be mated to 50 ohm connectors, as this could result in damage to the 75 ohm female center
conductor contact, and would produce an ureliable, unstable electrical connection.
