Triggered simultaneous acquisition/readout for PCIe digitisers

September 24, 2014 // By Graham Prophet
Capture triggered acquisitions at high speed without missed any events; Keysight Technologies has a firmware option for its U53xxA PCIe digitisersthat allows simultaneous capture and transfer of acquired data in triggered applications.

According to Keysight's own measurements, the digitiser’s architecture, with the new firmware, is able to sustain triggered acquisitions of thousands of samples at hundreds of kHz rates without missing any events. With the new firmware, it is possible to acquire and read substantially higher trigger rates during a shorter period of time (or non-periodic triggers) depending on the internal memory options selected. Users now can view the memory as a multi-bank circular memory, and can optimise the data throughput for their application by configuring the number of memory banks.

“The -TSR option offers an optimum solution for triggered applications that require a large volume of data transfer while making sure none of these triggers are missed,” said Jean-Luc Lehmann, product manager for Keysight PCIe high-speed digitisers. “This new function enlarges the coverage of OEM needs once more. Other specific functionalities, such as real-time peak detection and average, are already available.”

The triggered simultaneous acquisition and readout option (-TSR) is available now on the 8-bit U5309A and 12-bit U5303A PCIe high-speed digitisers.
