RIGOL DS1102E Oscilloscope smart Trigger captures fast rise-time noise transients

Exploring advanced trigger capabilities of RIGOL oscilloscopes using a home-made RF/EMI Probe. Just how good is Rigol trigger technology? How well can it capture noise? Can it handle some well-know difficult signals from e.g. quasi-resonant switchers built into switch-mode power supplies? Like transients from a power supply, it can be tricky to pin-down the source of troublesome EMI. We put the DS1102E trigger through its paces by asking it to tune-in to a specific risetime edge, so I can really explore the EMI-source and look at the shape of the tranisent. Trigger capabilities for the Rigol DS1052E and the Rigol DS1102E 50MHz and 100MHz Oscilloscopes include Edge, Pulse, Slope, Video and Alternate. #DS1102E
