The Agilent 85033E 3.5 mm calibration kit is used to calibrate Agilent network analyzers for measurements of components with 3.5 mm connectors up to 9 GHz. The 85033E calibration kit contains the following: Offset opens and shorts, and broadband load terminations. A data disk that contains the calibration definitions of the devices in the calibration kit for the PNA series. A data disk that contains the calibration definitions of the devices in the calibration kit for the 875x and 872x series. Two open-short-load (OSL) holders. 2.5 mm hex key for use with the (OSL) holder. Torque wrench. The broadband loads are metrology-grade, 50 ohm terminations which have been optimized for performance up to 9 GHz. The rugged internal structure provides for highly repeatable connections. A distributed resistive element on sapphire provides excellent stability and return loss. The offset opens and shorts are built from parts which are machined to the current state-of-the-art in precision machining. The offset short’s inner conductors have a one-piece construction, common with the shorting plane. The construction provides for extremely repeatable connections. The offset opens have inner conductors which are supported by a strong, low-dielectric-constant plastic to minimize compensation values. Both the opens and shorts are constructed so that the pin depth can be controlled very tightly, thereby minimizing phase errors. The lengths of the offsets in the opens and shorts are designed so that the difference in phase of their reflection coefficients is approximately 180 degrees at all frequencies.
