Note 2: Single / Multiple rail(s) for +12V is adjustable by a switch.

3.2 DC Voltage Regulation, Ripple and Noise

The power supply output voltages must stay within the following voltage limits when operating at

steady state and dynamic loading conditions. All outputs are measured with reference to the return

remote sense (ReturnS) signal. The +5V,+3.3V, +12V, -12V and +5VSB outputs are measure at the

power supply connectors references to ReturnS. The +5V and +3.3V is measured at its remote sense

signal (+5VS, +3.3VS) located at the signal connector.

Table 7 – Regulation, ripple and noise

Ripple and Noise shall be measured using the following methods:

a) Measurements made differentially to eliminate common-mode noise

b) Ground lead length of oscilloscope probe shall be  0.25 inch.

c) Measurements made where the cable connectors attach to the load.

d) Outputs bypassed at the point of measurement with a parallel combination of

10uF tantalum capacitor in parallel with a 0.1uF ceramic capacitors.

e) Oscilloscope bandwidth of 0 Hz to 20MHz.

f) Measurements measured at locations where remote sense wires are connected.

g) Regulation tolerance shall include temperature change, warm up drift and dynamic load
