Product No: EMI-9KA
R&S®ESR is an EMI test receiver compliant with the CISPR 16-1-1 standard. It supports both traditional stepped-frequency scans and optional FFT-based time-domain scans. Equipped with built-in preselection filters, a 20 dB preamplifier, and a highly linear front end, it offers an excellent balance of high dynamic range and high sensitivity. An optional real-time spectrum analysis feature—with a bandwidth of up to 40 MHz—includes spectrograms, persistence displays, and frequency-mask triggering, enabling the capture of elusive or sporadic emissions. The R&S®ESR is widely used for CE (conducted emission) and RE (radiated emission) certification testing across various sectors, including third-party certification laboratories, automotive electronics, new energy, consumer electronics and home appliances, industrial automation, rail transport, medical devices, IoT communications, lighting, and the defense and aerospace industries.
