EMI Test Receiver Includes FFT Capabilities

Rohde & Schwarz recently introduced the ESU family of CISPR16-1-1 compliant electromagnetic-interference (EMI) receivers with Fast Fourier Transform (FFT) time-domain scan capabilities. While traditional EMI measurements are time and labor intensive, the FFT capabilities in the ESU test receivers allows them to measure an EMI spectrum with a tremendous speed advantage over traditional spectrum-analyzer-based EMI receivers, increasing measurement speed by 10 to 100 times. The FFT capability is not meant to replace normal spectrum analysis measurement functions but to provide a quicker overview of an EMI spectrum profile. The ESU instruments also include full spectrum analyzer capabilities in three models operating over the ranges of 20 Hz to 8 GHz, 20 Hz to 26.5 GHz, and 20 Hz to 40 GHz. The analyzers feature a wide range of detectors, including CISPR average and RMS detectors, for making EMI measurements.
