Dual-frequency IP instrument is a kind of precise electronic instruments, and its error has strong influence to survey results. In order to check the characteristics of dual-frequency IP instruments, the authors have designed a simple RC-circuit. The authors have done the simulation test, and gotten satisfactory results.
