The R&S ESR7 EMI Test Receiver is a dual instrument that measures electromagnetic disturbances while simultaneously functioning as a fully featured, powerful signal and spectrum analyzer for lab applications. Rapid-fire-speed measuring occurs by the instrument's use of an FFT-based time domain scan and detailed analysis and history of disturbance signals is accomplished by realtime spectrum analysis using a wide variety of diagnostic tools. This robust and compact, dual instrument is user friendly with its straightforward display, intuitive touchscreen interface.
