The Center of Joint Usage “Terahertz quasioptics” contains the next apparatus:

• Scalar Network Analyzer P2-139 from Elmika for 0.17-0.22 THz frequency range.
• Quasi-Optical Radio Measuring Devices on the Basis of a Circular Hollow Dielectric Beamguide (HDB).

There are some applications of Quasi-Optical Radio Measuring Devices connected to Scalar Network Analyzer P2-139
