Abstract: A device and method for measuring spectrum parameters of a formation outcrop and a rock mass are provided. An excitation signal is generated by a direct digital synthesis (DDS) module of a signal transmission portion. A constant voltage mode or a constant current mode is adopted for observation. After the signal passes through a constant voltage/constant current module, a constant high-voltage signal source or a current source signal with constant current output is formed and output to ground through grounding electrodes A and B to establish a stable observation signal field source. Geoelectric response information under the excitation of each frequency signal is acquired by a signal receiving portion through grounding electrodes M and N, processed and send out to a microcontroller unit (MCU) for display and storage. The spectrum parameters at different depths are observed by adjusting geometric dimensions of AB and MN.
