Line Harmonics Test
This test checks the line harmonics to see if they meet EN 6000-3-2 pre-compliance levels. In addition, for
class C, tests differentiate devices above and below 25 W; for class D, a Current per Watt pre-compliance
test is provided.
1. Set up the source channels .
2. On the Power Analysis dialog choose Line Power Analysis and Harmonics Test.
3. Touch Class and select the equipment’s EN 61000-3-2 classification from the pop-up menu:

Class D, Personal computers and computer monitors, radio or TV receivers (75W-600W)
4. If you selected Class C, open the Limits dialog and choose the correct Active Input Power and Equip-
ment Type.
5. On the Power Analysis dialog, touch Frequency and select the line frequency at which the equipment
is operating. You can optionally select to Use Measured Frequency to enter the value as measured
by the current probe.
6. Touch Units and select Amps or dBuA (decibels referred to one microAmp).
7. Optionally, select Total Harmonic Distortion to see the contribution of each frequency to the total
distortion.
