Avionics Test Engineering Intern
Write a real answer. It is graded against the question's stored rubric, the mastery movement is computed by the same engine the product uses, and — the part worth watching — the next question is chosen by the real scheduler from what you have already answered. Nothing is saved and no tokens are spent.
Same bench as before: 100 MHz scope, 10x passive probe. Assume the probe is not the limiting element.
You measure a 7.0 ns rise time on a 100 MHz oscilloscope. Taking the scope's rise time as 0.35 divided by its bandwidth, and treating the measured, true and instrument rise times as combining in root-sum-square, what is the signal's actual rise time? Give the number, then say whether you would trust it.
This one resolves to a number. Give the value in the field below and your reasoning in the box — the number is checked exactly, by arithmetic.
