Easily debug and test designs that include I2C or SPI protocols using your Ininiium 90000 or 8000 Series scope

Lower-speed serial bus interfaces such as I2C (inter-integrated circuit) and SPI (serial peripheral interface) are widely used today in electronic designs for chip-to-chip communication. In many designs these serial buses tend to provide content-rich points for debug and test. However, since these protocols transfer bits serially, using a traditional oscilloscope has limitations. Manually converting captured 1’s and 0’s to protocol requires significant effort, can’t be done in real-time, and includes potential for human error. In addition, traditional scope triggers are not sufficient for specifying protocol-level conditions. Extend your scope capability with I2C and SPI Triggering and Decode application. This application makes it easy to debug and test designs that include I2C or SPI protocols using your Infiniium 90000 or 8000 Series scope.

• Set up your scope to show I2C or SPI protocol decode in less than 30 seconds
• Get access to a rich set of integrated protocol-level triggers
• Save time and eliminate errors by viewing packets at the protocol level
• Use time-correlated views to quickly troubleshoot serial protocol problems back to their timing or signal integrity root cause

I2C and SPI protocol triggering and searching for 90000 Series

Get access to a rich set of integrated protocol level triggers. The application includes a suite of configurable protocol-level trigger conditions specific to I2C and SPI. The application uses software-based search triggering when serial triggering is selected. With software-based protocol triggering, the oscilloscope takes signals acquired using either scope or digital channels and reconstructs protocol frames after each acquisition. It then inspects these protocol frames against specified protocol-level trigger conditions and triggers when the condition is met.
