Reference sources are compact signal sources that facilitate the calibration of EMC test equipment. There are 2 types... conducted and radiated........
The Conducted source (CRS+) is simply plugged directly into a LISN or used with a voltage probe and will check the calibration of the complete measurement system.
The Radiated source (ERS) will check both the site and the measurement equipment. This is particularly important as the greatest source of measurement uncertainty is invariably the site.
All references sources are supplied complete with calibration data which for both the CRS+ and the ERS are traceable to NPL (UK)
