摘　　要：本文介绍采用标准磁场法和标准环天线法研制完成的国家高频磁场标准装置。其工作频率为１０ｋＨｚ～３０ＭＨｚ；发射场强为１～１００ｍＶ／ｍ；不确定度为０．２５ｄＢ。标准磁场法装置与标准环天线法装置的比对一致性为０．４５ｄＢ；标准环天线装置与ＴＥＭ室标准场装置的比对一致性为０．４０ｄＢ。This paper reports the development of HF magnetic field standard in China. It has beed completed recently by using the standard magnetic field method and standard loop antenna method, A standard test loop antenna of 100mm in diameter transmits HF magnetic field to be received by another standard loop antenna of 300mm in diameter. The frequency range is 10kHz-30MHz, the transmitting field strength is 1-100mV/m and the uncertainty is 0.25dB. The setups by using the standard magnetic field method and the standard loop antenna method are consistent within 0.45dB. The setups by using the standard loop antenna method and that by using a TEM cell of 3. 6m×1.8m×1.8m are consistent within 0. 40dB.
