Product Description:
R&S ESR is an EMI test receiver, including ESR3, ESR7, ESR26, frequency range between 10 Hz-26.5 GHz and comply with CISPR 16-1-1 standard. ESR serial receiver can be used as an EMI receiver or as a spectrum analyzer, which can fully satisfy the test requirements of R & D engineers.
Ltd. is the agent of R&S company to provide all test products and test accessories.
Feature Description:
The receiver can measure electromagnetic interference by means of a conventional stepped frequency sweep or by means of an FFT-based time-domain sweep at very high speeds. At the same time, the R&S®ESR also serves as a powerful, full-featured signal and spectrum analyzer for laboratory applications. With real-time spectrum analysis and a wide range of diagnostic tools, the test receiver can be used to analyze interference signals and their history in detail. The R&S®ESR is easy to operate in all modes thanks to clearly structured menus and an intuitive touch screen.
