Tektronix introduced protocol decode, triggering and analysis support for the MIPI Alliance's System Power Management Interface (SPMI) for its 5 and 6 Series MSO mixed signal oscilloscopes. The new software option takes advantage of the leading-edge capabilities of these oscilloscopes including the productivity of touch-based setup, one of the industry's largest 15.6-in HD display for showing multiple buses and low-noise power rail voltages.
SPMI is used to connect processors in mobile devices to one or more power controllers and enables processors to dynamically increase or decrease power to specific subsystems for reduced power consumption. With Tektronix' SPMI decode option, users can easily decode bus activity, saving time and reducing frustration compared to attempting to decode bus activity manually. Bus sequences are displayed with clear color-coding indicating sequence starts, master IDs, commands, addresses, data, and acknowledgments (more info).
