Remote Sensing (+12VRS)
The power supply system output shall have remote sense (12VRS) to compensate for drops
in the system for the +12V output. The remote sense input impedance to the power supply
shall be greater than 200 ohms on +12VRS. Remote sense shall be able to compensate for
a minimum of 400mV drop on the +12V output. The current in any remote sense line shall be
less than 5mA to minimum voltage sensing errors.

No load operation
The power supply shall meet all requirements except for the transient loading requirements
when operated at no load on all outputs.

3.5.4
Regulation, ripple and noise
The power supply shall meet the regulation, ripple and noise limit under all operating
conditions (AC line, transient loading and output loading). The regulation shall be measured
at the output connector of the power supply, subject to the cross loading conditions in the
following table.

Ripple and noise
Ripple and noise are measured with 0.1uF of ceramic capacitance and 10uF of tantalum
capacitance on each of the power supply output connector terminal. The ripple and noise
shall be met over all load ranges and AC line voltages. The output noise requirements shall
apply over a 0 Hz to 20 MHz bandwidth.

The power supply shall operate within specified limits and meet regulation requirements over
the following transient loading conditions anywhere within the specified load range of the
power supply. This shall be tested with no additional bulk capacitance added to the load.
