Keysight digitiser learns continuous streaming

29 April 2015 Test & Measurement

Keysight Technologies introduced continuous simultaneous acquisition and readout (CSR) for its U5303A 12-bit PCIe digitiser.

In addition, complete data recording software applications are available, such as digitiser streaming (application option CB0) and digital down-converter streaming (application option CB1).

The firmware option CSR allows engineers to perform acquisition and readout simultaneously and in a continuous way. They can use several mechanisms to adapt the acquisition data rate to the targeted application. A gapless acquisition can be sustained at a high data rate due to the PCIe Gen2 x 8 interface. An entire range of new application possibilities are enabled by this option, which includes real-time, GPU-based data processing systems and data recording systems.

CB0 is an application option which implements a real-time digitiser data recorder. Based on the CSR architecture, it provides a command line interface and an easy to use data viewer. Recording performance up to 1 GBps is ensured in a specific qualified system.

CB1 provides the same functionality as CB0 and adds real-time digital down-converter functionality. Recording performance up to180 MHz instantaneous bandwidth is ensured in a specific qualified system.
