Uprated acquisition capabilities for PCIe digitisers

March 20, 2015 // By Graham Prophet
Keysight Technologies has added a continuous simultaneous acquisition and readout (CSR) facility to its U5303A 12-bit PCIe digitiser. Complete data recording software applications are available, such as digitiser streaming and digital down-converter streaming.

The U5303A 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 is enabled by the CSR 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, the CB0 provides a command line interface and a data viewer. Recording performance up to 1 GB/sec 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.

“Numerous test scenarios require gap-free or continuous acquisition of digitised data for minutes, hours or days.” said Keysight’s Giovanni Lucia, R&D engineer for hardware and firmware. “Signal monitoring, software defined radio, atmospheric research, telemetry systems and medical imaging are examples of such applications. We designed the CSR option with the intent of providing an easy and effective implementation to simplify the integration in any OEM system. Furthermore, the CB0 and CB1 applications provide a reliable and cost effective data recording system for customers who want a ready to use solution.”
