Unfortunately, I don't have the tool(s) necessary to view those files. Perhaps someone does. I want to mention, though, that the ringing in the scope image is not so much noise as it is either an impedance mismatch, or parasitic capacitances and inductances in the circuit (those that are not part of the design, but exist as by-products of lead length, PCB traces and materials, etc, used to construct the circuit) that resonate (ring) at their characteristic frequency. So, in addition to proper layout for noise, lead and trace lengths must be as short as possible, and not run too close together. Any cables into and out of the amplifier of any significant length must be constant impedance (coaxial, twin-lead, etc) cables and matched to the input/output impedance at each end.
