Rohde & Schwarz builds the industry standard EMC instruments and systems. We are known throughout the world for supporting the EMC community with the latest technology. Wherever your measurements fit within the EMC world, full compliant down to board level debug, we have an instrument or system for you.
EMC testing takes two forms, testing for Emissions (commonly called EMI) and Immunity (also called susceptibility). Emissions tests look for the two ways harmful signals are propagated; radiated into the air and conducted across cables and wires. Similarly, immunity testing is performed to simulate the two ways signals are coupled into a device, over the air signals (radiated) and signals over cables (conducted).
Emissions and immunity are two sides of the same coin. Regulatory bodies like the FCC in the USA have stated that a device must not propagate any emissions above a certain limit. Good product design requires manufactures to test for product’s immunity to propagated signals, or their susceptibility to these signals. Since the propagation method is the same in both cases, there is a test for radiated emissions and radiated immunity, and the same applies to conducted emissions and immunity. The links in the Emissions and Immunity graphic will open up specific information on each type of system or instrument.
