| Summary: | In technical cybernetic systems, it is impossible to do without exchanging information between devices. To analyze signals inside systems and devices, specialized devices – oscilloscopes – are used. They allow observation of signal shape over time. In some applications, an oscilloscope galvanically isolated from the 230 V mains may be required. Sometimes this possibility can be realized by powering the network oscilloscope from the battery. The relevance of the work is especially evident when it is difficult to get certain equipment or it has a high cost. This article discusses the modernization of the OWON SDS1102 digital oscilloscope by adding the possibility of battery power using the LM338 step-down linear converter. The article will be useful for students, graduate students and engineers who want to implement galvanic isolation from 230 V network for an oscilloscope. |
