N5391B I²C and SPI Protocol Triggering and Decode for Infiniium scopes

Product Status: Discontinued | Currently Supported
This product is no longer available

Key Features & Specifications

Key features:

  • 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.

Ordering information:

  • Order N5391B for a user-installed license
  • Order Option-007 for a factory-installed license with a new 9000A or 9000 H-Series oscilloscopes
  • Order N5435A, Option-006 for a server-based license

Compatible oscilloscopes:

  • Infiniium 9000A or 9000 H-Series oscilloscopes


This application includes a suite of configurable protocol-level trigger conditions specific to I²C and SPI. When serial triggering is selected, the application enables special real-time triggering hardware to ensure that the scope never misses a trigger when armed.

The multi-tab protocol viewer includes correlation between the waveforms and the selected packet, enabling you to quickly move between the physical and protocol layer information using the time-correlated tracking marker.
