Present status and development tendencies in the field of high frequency measuring techniques
The status of RF measurements and future trends in research and development are reviewed. The definition of the basic units of the international system and the uncertainties with which a basic quantity can be related to these units in the best case are reviewed. For tracing RF quantities to the basic units the (Physical-technical Federal Institute) standard measuring devices for RF power, RF voltage, RF attenuation and RF impedance were established, particularly in the frequency range between 100 kHz and 18 GHz. Only in one case (RF power) is the frequency range enlarged to the range from 26.5 GHz to 40.0 GHz. Waveguide noise standards exist in the waveguide X-band between 8.2 GHz and 12.4 GHz. Quantities of the electromagnetic field are measurable between 10 kHz and 3 GHz.
