AXIe in Big Physics Experiments
|
By Frank Corry and Sophia-M Bowers
Big physics experiments are critical for the advancement of fusion research (which holds the promise of clean sustainable energy), and particle physics research (which seeks to understand the origins of the universe through investigation and discovery of sub-atomic particles). These are often single-shot experiments, meaning researchers must take care in the design and set up of the experiment as they only have one chance to capture the data. Experiments can easily require tens of data acquisition channels, and some may even require hundreds, with many of these channels being digitizers that record short transient signals, providing an insight into dynamic phenomena. These high channel count systems must be integrated into the hardware environment of the experimental machine, which can be problematic due to space and power constraints.
AXIe provides a robust platform for big physics experiments, with AXIe based digitizers offering industry leading digitizer performance and channel density. For example:
- For performance, Keysight’s M9710A provides 4 channels with 10-bit resolution at 5 GS/s, and with up to 8 GB of acquisition memory. It can also operate in interleaved mode, providing 2 channels with 10-bit resolution at 10 GS/s.
- For flexibility, Keysight’s M9703B provides 8 channels with 12-bit resolution at 1.6 GS/s, and with up to 16 GB of acquisition memory. It can also operate in interleaved mode, providing 4 channels with 12-bit resolution at 3.2 GS/s.
- For channel density, Keysight’s M9709A provides 32 channels with 8-bit resolution at 1 GS/s, and with up to 16 GB of acquisition memory.

Optical Interfaces to Address 5G Test
|
By Larry Desjardin, Modular Methods
One and a half years ago, six companies along with the AXIe Consortium and the VITA trade industry group endorsed a new standard called Optical Data Interface, or ODI.
ODI is a high-speed interface for instrumentation and embedded systems, supporting speeds up to 80 GBytes/s. With Keysight Technologies’ unveiling of an ODI-based system last month at the Association of Old Crows (AOC), Conduant Corporation’s offering of ODI-based RAID storage systems, and Guzik Technical Enterprises’ previously announced digitizers and processing modules, ODI is now positioned to address difficult challenges in 5G communications, mil/aero systems, and high-speed data acquisition.
Before I dive into the new offerings from Keysight and Conduant, it’s time for full disclosure. I’m not a disinterested observer, for I’m the technical chairman of the ODI specification committee, hosted by the AXIe Consortium. You can read my EDN column about ODI for a technical overview or access the ODI technical specifications directly.
