include: Blue Angel* system requirements, RAL-UZ 78, US Presidential executive
order 13221, ENERGY STAR*, ErP Lot 6 requirements (2010 and 2013 levels), and
2014 ErP Lot 3 requirements. Additionally, if any Computers use an Alternative Low
Power Mode (ALPM) then the +5VSB standby efficiency has similar requirements as
shown below.

4.2.5 Output Ripple Noise (Required)
The output ripple and noise requirements listed in the Table 4-6 must be met
throughout the load ranges specified for the appropriate form factor and under all
input voltage conditions as specified in Table 4-1.
Ripple and noise are defined as periodic or random signals over a frequency band of
10 Hz to 20 MHz. Measurements must be made with an oscilloscope with 20 MHz of
bandwidth. Outputs should be bypassed at the connector with a 0.1μF ceramic disk
capacitor and a 10 μF electrolytic capacitor to simulate system loading. Refer to Figure
4-1 for the differential noise measurement setup.
