(2) Ripple & noise are measured at 20MHz of bandwidth by using a 20"twisted par-wire terminated with a 0.1uF & 47uF parallel capacitor.
(3) Tolerance:includes set up toletance,line regulation and load regulation.
(4) Line regulation is measured from low line to high line at rated load.The power supply is considered acomponent which will be installed into a final equipment.
(5) The dinal equipment must be re-confinnned that it still meets.EMC directives.For guidance on how it perform these EMC test,please refer to EMI tesing of component power supplies.
