Margining is usually one of the more difficult parts of an analog power implementation. Using the OmniOn Power DPI GUI, it is as easy as clicking on the Margin selection. This provides easy access to a range of options: Margin Off (the default), Margin Low or Margin High, with the option to ignore on fault. As an example, pick Margin Low and ignore on fault and then click “Write Settings”. The module is now running at the margin low set point set in the input box below. The speed at which a system can be characterized using just a user interface should be becoming more apparent now. A complex activity is replaced with a click on a screen. To turn margin off, select it from the margin selection for the module and click “Write Settings” again.
