The ESR is an EMI test receiver build to measure electromagnetic disturbances using conventional stepped scans or ultrafast FFT based time domain scans. It also functions as a powerful signal and spectrum analyzer. The receiver features real-time spectrum analysis with a wide range of diagnostic tools for detailed analysis of disturbance signals and their history. With these tools, users can detect hidden or sporadic emissions and analyze their causes.
The ESR comes with intuitive menus on an easy to use touchscreen. Compact dimensions, low weight, optional ruggedized housing and optional DC power supply make the R&S®ESR an ideal choice also for mobile applications.
