基于 TEM 小室的探头校准系统不确定度评定
The Uncertainty Estimation for the Probe Calibration Results Employing a TEM Cell
摘要
Abstract
The TEM cell is used widely as an electromagnetic field generator,and by employing it,a probe calibration system can be set up to calibrate the radio frequency electromagnetic field probe. A probe calibration system working at 300 kHz ~ 100 MHz is analyzed,and the measurement result uncertainty is presented for a magnetic field probe at five different frequencies in that range. The analysis takes into account the effect of the wave impedance inside the TEM cell,and that of the interaction between the probe and the standard field etc,which can be a useful guide to analyse the electromagnetic field probe calibration process.关键词
