Hi,

Do you have a block diagram and schematic to share? I am trying to understand how the amplifier is part of the issue.

Thanks
David

Thanks for feed back, here is the illustrate;

1.Voltage input to amplifier from power supply.

2.Voltage getting out to PC (IEEE card is located in this PC),
we also have 100Ω resistance between output of amplifier and PC.

Hi,

Thanks for the information. Where does this amplified voltage applied in the PC and how does this voltage being connected to the IEEE card?

Hi,

Is this a AC power noise test or a DC bus power test? What is the purpose of the test?

Thanks
