| Abstract: | Resonance method is a method of measuring the parameters of RLC. However, how to keep frequency stability and shorten the measuring time are two major problems and must be solved in this method. In this paper, a high performance RLC instrument design based on DDS is introduced. The requirement of high precision is satisfied perfectly by employing DDS. The circuit parame-ters of hardware and corresponding software flow of system are described in detail, and the methods of improving performance are summarized as well. |
