Sliding Terminations

General

A sliding termination (or sliding load) consists of a precision, movable, tapered termination in a highly accurate, air dielectric transmission line.

These instruments are basic tools for precision microwave measurements. One general application is "load separation" measurements in which the reflection from the terminating element can be separated from that of the test device. Load separation using sliding loads is a key element in the calibration of vector network analyzers (VNAs). The technique is also used in the measurement of the reflection from two-port devices, particularly "non-insertable", (e.g., waveguide-to-coax adapters, and the directivity of directional couplers).

We manufacture sliding terminations which offer a range of performance and convenience features. These include metrology grade and high precision units with integral, dedicated connectors; precision units which permit changing the sex of the connector within the same connector series; and true, modular instruments which permit changing the connector type.
