6. Triggering? All scope manufacturers are adding new triggering features to their products. These features are important because they allow for triggering on very specific events. This can be a valuable troubleshooting tool because it will let the user prove whether a suspected condition exists or not. Extra triggering features add complexity to the scope’s user interface; so be sure to try them out to make sure that they can be applied.
7. Trustworthy display? Three factors critically affect a scope’s ability to display the unknown and complex signals that are encountered in oscilloscope applications. If the user loses confidence in the scope’s ability to correctly display what is going on at its probe tip, productivity will take a real hit. These are display update rate, dead-time, and aliasing.
