Microwave device is configured to supply a microwave signal, so as to vary over a range of frequencies, the microwave source can be connected to a load, the frequency of the microwave signal provided by operating the source As the control means has, and a microwave detector for performing microwave measurements during operation, measurement is performed a plurality of receiving and transmitting microwave signals to the load and / or reflected microwave signals, from the load is placed, corresponding to one of a plurality of different frequencies of the frequency range, a microwave detector, the measurement of the plurality, each measurement, the transmitted microwave signals and / or measure, of the reflected microwave signal I have provided a means for determining a measure. [Selection] Figure Figure 1マイクロ波装置は、マイクロ波信号を供給し、負荷に接続可能なマイクロ波ソースと、動作中前記ソースによって供給される前記マイクロ波信号の周波数を、ある周波数範囲に亘って変化させるように構成された制御手段と、マイクロ波測定を行うためのマイクロ波検出器であって、動作中、負荷からの反射マイクロ波信号、及び/又は負荷への伝送マイクロ波信号を受け取って複数の測定を行うように配置され、各測定は、前記周波数範囲の複数の異なる周波数の1つに対応する、マイクロ波検出器と、前記複数の測定から、反射マイクロ波信号の測度、及び/又は伝送マイクロ波信号の測度を決定する手段とを備えている。【選択図】図1
