In one method of calibrating an instrument having N ports, where N&#x3e;=2, cables of a first type are characterized by connecting a first cable between two of the ports; performing an 'unknown-thru' full two-port calibration between the two ports; obtaining a S-parameter of the first cable; saving the S-parameter of the first cable; and then repeating the connecting, performing, obtaining and saving for additional cables having the first type. The cables having the first type are then disconnected from one of the two ports and a measurement plane is transferred from the connected end of the cable to the disconnected end of the cable. Cables of a second type are then characterized by connecting a second cable between the second of the two ports and the disconnected end of the first cable; measuring a S-parameter of the second cable; and saving the S-parameter of the second cable.

Self calibration apparatus and methods

A directional bridge for measuring propagated signals to and from a source device to a load device where both the source device and load device are in signal communication with the directional bridge is disclosed. The directional bridge may include a first bridge circuit network and a first sensing element in signal communication with the first bridge circuit network. The first sensing element may produce a first measured signal that is proportional to the propagated signals.

Integrated directional bridge

An interconnection includes a microcircuit package having a slot, and a receiving feature. A bead ring is fitted into the receiving feature. A center conductor extends through a dielectric support disposed in the bead ring and through the slot. The center conductor forms a coaxial transmission structure in cooperation with the bead ring and the dielectric support, and forms a slab line transmission structure in cooperation with the slot.
