The power supply shall meet all requirements except for the transient loading requirements when
operated at no load on all outputs.
3.2.2.5 Voltage Regulation
The power supply shall meet the Voltage regulation under all operating conditions ( AC line,
transient loading, output loading ). These limits include the peak-peak ripple/noise. The regulation
of Table 14 shall be measured at the output connector of the power supply, subject to the dynamic
loading conditions in paragraph 3.2.2.7.

3.2.2.6 Ripple and Noise Regulation
Ripple and Noise is defined in table 15. Ripple and Noise shall be measured over a Bandwidth of
0Hz to 20MHz at the power supply output connector. A 0.1μF ceramic capacitor and 10μF of
tantalum capacitor shall be placed at each point of measurement. The measurement points shall be
as close as possible to the point of load.
The ripple and noise specification shall be met over all load ranges and AC line voltages with 1+1
power supplies in parallel operation.

3.2.2.7 Dynamic loading
The power supply shall operate within specified limits and meet regulation requirements for step
loading and capacitive loading specified below.
The load transient repetition rate shall be tested between 50Hz to 5kHz at duty cycles ranging . The
load transient repetition rate is only a test specification. The Δ step load may occur anywhere
within the MIN load and the MAX load.
This shall be tested with no additional bulk capacitance added to the load.
