Agilent Technologies unveils serial bus triggering and 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 ideal in a wide range of embedded applications.

"Unfortunately, designers have been unable to view these buses with their traditional portable oscilloscopes," said Jay Alexander, vice president and general manager of Agilent Technologies' oscilloscope business.

"Until now, they have had to use more expensive bench oscilloscope models. With this introduction, engineers can troubleshoot their embedded designs quickly with a very affordable oscilloscope."

The Agilent 5000 series 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.

To make it even easier to find and debug errors, the optional Agilent N5423A I2C/SPI, the N5457A RS-232/UART and the N5424A CAN/LIN protocol decode toolsets give designers hardware-accelerated decoding that updates at rates matched only by other Agilent oscilloscopes.
