Command Syntax
:POWer:HARMonics:APPLy
The :POWer:HARMonics:APPLy command applies the current harmonics analysis.
Switching power supplies draw a range of harmonics from the AC mains.
Standard limits are set for these harmonics because these harmonics can travel
back to the supply grid and cause problems with other devices on the grid.
Use the Current Harmonics analysis to test a switching power supply's current
harmonics to pre-compliance standard of IEC61000-3-2 (Class A, B, C, or D). The
analysis presents up to 40 harmonics.
