Power Influence Test
The Power Influence test allows you to view the effects of interference
from a 50 Hz or 60 Hz power source (AC mains) on the circuit under test to
include graphical display of third triplet power harmonics up to 20KHz,
which can aid in troubleshooting noisy circuits. The results of the power
influence test are also in graphical form.
Power Influence
The Power Influence function displays and updates results in real time,
until you stop the test. The last valid results then remain displayed. The
page also displays a value and graph of the Power Influence
measurement, and pass/fail status.

1. From the Copper main menu Test Groups, tap Noise test
.
2. From the Tests menu, tap Power Influence icon to start the test.
By default, the Power Influence page opens.
3. Use the graph controls to maneuver the graph. Refer to Graph Controls
on page 19 for more information.
