Primary Standards
-
Primary standards (often also referred to as mechanical dead-weight testers, pressure balances or primary pressure standards) are the most accurate reference instruments for pressure. Their functional principle is based on the physical principle of pressure = force/area. Mass pieces placed on the top of a piston-cylinder system are the source of a precisely defined force. By producing a certain (counter) pressure inside the primary standard an equilibrium is achieved: the mass pieces, including the free-running piston of the piston-cylinder system, are floating, which will lead to a very accurate pressure at the test port which measured through piston gauge technology.

VXI Switching
-
The Aerospace and Defense industries were early adopters of modular test platforms. One of the first successes was VXI test systems and VXI switching. They served these industries very well for more than 20 years. Now, as VXI test systems become obsolete, test systems developers are looking to PXI as the next generation modular test platform for their industries. We offer a few different references to help you in making a switch to PXI.

Waveguide Switches
-
Waveguide switches are electromagnetic switches with hollow circular or rectangular cross-sections and are used for routing RF energy in microwave communications, broadcasting, and in radar applications. Waveguide switches can be used to transfer both power and communication signals, and the bandwidth of a waveguide is in relation to its size, and thus always referred to by its size (e.g. WR112, WR90, WR75 etc.). Compared to coaxial switches, waveguides can route extremely high power signals over a narrow bandwidth at low to high frequencies, and now Lightweight Waveguide series is available.
