DC2130A - Schematic3/17/2014
Demonstration circuit 2130A, when used with a spectrum analyzer, makes conducted EMI measurement of DC/DC converters convenient over a wide range of frequencies and EMI levels – beyond the highest automotive conducted EMI test frequencies and below the EMI levels generated by power electronics with the latest chip and printed circuit board designs for low noise. Measurements above 108MHz, which is the high-end of the CISPR 25 conducted EMI frequency range, are beneficial to predict radiated measurement results from open area test sites (OATS) or anechoic chambers (ALSE = Absorber-lined shielded enclosure) without the expense and effort associated with those testing methods.
