Ripple Measurements

In the following table you will find the ripple levels that we measured on the main rails of CSP-S1000. According to ATX specification the limits are 120 mV (+12V) and 50 mV (5V & 3.3V).

Ripple Measurements
Test	12 V	5 V	3.3 V	Pass/Fail
20% Load	12.2 mV	4.0 mV	4.8 mV	Pass
40% Load	16.2 mV	4.4 mV	5.2 mV	Pass
50% Load	18.2 mV	4.8 mV	5.8 mV	Pass
60% Load	22.4 mV	5.4 mV	6.6 mV	Pass
80% Load	30.6 mV	6.4 mV	8.2 mV	Pass
100% Load	41.4 mV	7.8 mV	10.4 mV	Pass
Crossload 1	11.8 mV	3.6 mV	4.4 mV	Pass
Crossload 2	41.6 mV	8.8 mV	11.2 mV	Pass

Ripple suppression is very good, especially on the minor rails where the maximum Peak to Peak voltage we measured barely reached the 1/5th of the ATX specification limit (50 mV).

Ripple at Full Load

In the following oscilloscope screenshots you can see the AC ripple and noise that the main rails registered (+12V, 5V, 3.3V). The bigger the fluctuations on the oscilloscope's screen the bigger the ripple/noise. We set 0.01 V/Div (each vertical division/box equals to 0.01V) as standard but sometimes we are forced to use 0.02 V/Div, meaning that the fluctuations will look smaller but actually this wont be the case.
