Electronic design and engineering (EDE)

For the development and testing of electronic designs, general purpose test equipment is essential. It is also required for production, installation and maintenance of electronic devices and systems. The most versatile test instrument in this regards is the oscilloscope. Modern oscilloscopes are used for multiple functions in the design and engineering process of electronic components consisting of analog, digital and RF parts. Use ranges from simple voltage and current measurements to more sophisticated applications such as power analysis. Trigger and decode on data and communication buses are also common oscilloscope applications, similar to signal integrity and jitter analysis on high-speed serial links. Rohde & Schwarz oscilloscopes offer even more functionality, enabling users to carry out RF and spectrum analysis or perform EMI debugging on an engineer’s desk. Our oscilloscope solution includes:
