Abstract: The portable high-frequency digital magnetotelluric system uses only two DC 12V rechargeable car batteries for power supply. The advatange and field operation of the system, the function of the major hardware and software, the flow diagram of data processing and the obtained results are briefly described in this paper. This system possesses the following peculiarities:1. The frequency band (256Hz-4096 s.) is wide;2. Lower power consumption. Two DC 12V rechargeable batteries can be used to operate the system continuously for 24 hours;3. The system is light in weight, and is convenient to be used in the field;4. Complete softwares are available for data collection and transmit, calculation of system response, auto-inverse interpretation and comprehensive drawing etc.. These softwares are efficient, flexible and convenient.

Key words: High-lrequency magnetotelluric system, Hardware, Software, Response of system, Processing results
