Keysight Technologies Introduces Triggered Simultaneous Acquisition and Readout Capability for PCIe Digitizers

Triggered Simultaneous Acquisition and Readout Capability for PCIe Digitizers | In Compliance Magazine

Keysight Technologies, Inc. announced the availability of new signal processing firmware for its family of U53xxA PCIe digitizers. The new firmware (option -TSR) allows simultaneous capture and transfer of acquired data in triggered applications.

According to Keysight’s validation measures, the digitizer’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. Moreover, 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 optimize 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 digitizers. “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.”
