Transient electromagnetic signal not only attenuates slowly in the late stage, but also is weak and submerged in noise. According to analyzing the characteristics of transient electromagnetic signal, the new transient electromagnetic receiver utilizes a 24-bit A/D conversion technology, two_stage programmable amplification and low-pass-filter, combining vertical configuration of boards, for improving the resolution which is difficulty for the old receiver in the open. The max resolution of system can attend 0.05 μV. The dynamic range will be 162 db. It´s more adaptable to working in the harsh environment.
