Serial bus triggering, hardware-based decoding

Agilent Technologies has introduced serial bus triggering and real-time decode support for its 5000 Series oscilloscopes. These capabilities give embedded system developers greater insight into their designs' CAN (controller area network), LIN (local interconnect network), I2C (inter-integrated circuit), SPI (serial peripheral interface), RS-232/UART and USB (universal serial bus) serial buses.

Having these capabilities in the 5000 Series eliminates the need for a more expensive bench 'scope and accelerates the troubleshooting process. CAN, LIN, I2C, SPI, RS-232/UART and USB buses were designed to meet specific needs in applications such as automotive control and chip-to-chip communications.

In recent years, these low-speed serial buses have replaced proprietary serial and parallel buses in most embedded designs. Their low cost and breadth of development tools make them popular in a wide variety of embedded applications.

The oscilloscopes now offer triggering for these buses as a standard feature. Customers who already own a 5000 Series 'scope can add this feature by downloading firmware version 5.0 or higher from There is no charge for the firmware download.
