If you plug your product’s power cord into any unregulated standard factory ac main, there is a possibility that the power you are using could corrupt any testing you do. The quality of ac power can degrade the performance of equipment being tested. Corrupted ac power can make equipment appear to be on-spec when it is off-spec, or off-spec when it is on-spec. Either way, bad test results can be costly. They can bring unnecessary engineering time spent fixing non-poblems, or worse, result in costly fixes of faulty units in the field, with a simuaneous loss of customer confidence
