Brief Description
The ESR is an EMI test receiver for the frequency range from 10 Hz to 26.5 GHz and complies with the CISPR 16-1-1 standard. It measures electromagnetic disturbances with the conventional stepped frequency scan or ? at an extremely high speed ? with an FFT-based time domain scan. At the same time, the ESR functions as a full-featured, powerful signal and spectrum analyzer for lab applications. Featuring realtime spectrum analysis capability with a wide range of diagnostic tools, the test receiver also enables detailed analysis of disturbance signals and their history. The ESR comes with clearly structured menus and an intuitive touchscreen, making it very easy to operate in any mode.
