Lab Instrumentation — question 5 of 10
Write a real answer. It is graded against the question's rubric, and the mastery movement is computed by the same engine the product uses. Scoring here is deterministic rather than model-written, so this page costs nothing to run and nothing is saved. In a track built from your own posting, the same rubric is graded by the model, which is what produces feedback about your reasoning rather than about coverage.
You're trying to catch the moment a 5V rail droops during power-up -- it happens once, right as the board turns on, and never again until you power-cycle it. Your scope is connected with the trigger mode left on Auto and the display rolling continuously. You power-cycle the board several times but never seem to catch the droop on screen. What's wrong with your trigger setup, and how would you change it to reliably capture that single event?
