The 2-GHz top-of-the-line RTO models employ a purely digital trigger system that eliminates the alignment errors that can occur with software-compensation schemes used in conjunction with separate analog triggers, with RTO trigger jitter specified in femtoseconds, vs. picoseconds. In addition Wolf said, the digital trigger eliminates re-arm times associated with analog triggers (which can mask events of interest that occur shortly after an analog trigger). The RTO provides up to 20 times less blind time than competitive models to help identify intermittent problems.
RTO models are available in 2- and 4-channel models with bandwidths of 1 and 2 GHz. Sampling rate is 10 Gsamples/s. The instruments support a Windows-driven touch-screen user interface. (Dr. Markus Freidhof, head of R&D for oscilloscopes, provided a user-interface demonstration that text can’t do justice to.)
The new RTM models offer 500-MHz bandwidth and 5-Gsample/s sampling. They forgo the touch-screen interface but boot within seven seconds to help provide fast measurement results.
