The E7400A-series EMC spectrum analyzers, also called an EMI receiver, reduces the cost of achieving EMC compliance by providing the capability of detecting unwanted radiated and conducted emissions during the design stage. The E7400A series provides the capabilities you need in an analyzer to make in-house EMI precompliance testing a reality.
When combined with a broadband antenna, the E7400A provides the capabilities to check for radiated emissions coming from your DUT. This is best done in an area that is free from reflective objects such as an open area or EMI chamber.
Test for noise or interference placed on power or data lines by coupling the E7400A instrument to the power or data line through a line impedance stabilization network (LISN) device or absorbing clamp.
