- 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 display capabilities of these oscilloscopes, including their 15.6-inch touchscreen configuration to allow multiple bus and power rail voltages to be viewed.
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. Bus sequences are displayed with color-coding indicating sequence starts, master IDs, commands, addresses, data, and acknowledgments.
The SPMI software option goes beyond simple decode and gives users the ability to trigger the scope on specific bus activity and search through acquisitions.
Other features include the ability to check bus sequence timing and compare bus activity to embedded software with a time-stamped decode table and to correlate bus activity with voltage and current measurements on voltage regulator outputs.
The 5-SRPM and 6-SRPM options are available now and priced at $1,850 US (1730€) MSRP each.
