If you get the "Sorry, the file cannot be displayed. There seems to be a technical issue ..." error when trying to view an image, a workaround is to click on the cog icon in the upper right side of the media viewer, and then select "Disable Media Viewer". We are aware of the problem and are looking for a solution.
It consists of a Schmitt trigger that is driven from a single-ended input coming from a BNC connector on the front panel. The Schmitt trigger produces balanced output signals with controlled source impedance. The normalizing capacitor is adjusted using a procedure similar to adjusting probe compensation. When adjusted correctly, the voltage division ratio formed by the plug-in's output impedance and the mainframe's input impedance should be a real value which does not change across the specified frequency range of the scope. After the scope is normalized using the 067-0500-00, other plug-ins can be adjusted to produce clean transient response in the normalized scope.
