10-Bit PCIe High-Speed Digitizer running at 10 GS/s

Keysight U5310A14 July 2016 - Keysight Technologies launched the U5310A 10-bit PCIe high-speed digitizer running at 10 GS/s. With its very-high dynamic range and 10-bit resolution across a wide 2.5 GHz bandwidth, the high-speed digitizer allows the capture of fast transients with high fidelity.

This unique ADC card is designed for embedded OEM applications, such as medical research, analytical time-of-flight (MS-TOF), environmental monitoring (LiDAR), ultrasonic non-destructive testing (NDT), semiconductor testing and distributed strain temperature sensor (DSTS). Furthermore, the U5310A is ideal for advanced physics experiments using single-shot or event-based applications.

The new U5310A high-speed digitizer features two channels with 10-bit resolution, simultaneous sampling at up to 5 GS/s, and an unrivaled 10 GS/s in interleaved mode. With a DC up to 2.5 GHz bandwidth, this digitizer provides on-board real-time averaging at full sampling rate and large 4 GB memory.

Keysight developed new proprietary ICs for the U5310A. In particular, the low distortion and low noise LDNA front-end amplifier IC to drive the ADC. This key component provides single ended to differential outputs with a distortion from 10 to 15 dB lower than the distortion of the ADC—therefore overall performance is not impacted.

Keysight also designed a low noise dedicated QMCK clock IC with very low 25 fs jitter. This specific IC drives the two ADCs, minimizing jitter. Moreover, the TRAC trigger IC provides time precision of 15 ps RMS.

“With its new design and outstanding performance, such as exceptional signal-to-noise ratio, minimum overshoot and flat frequency response, the U5310A allows unequalled measurement capabilities for time and frequency domain applications,” said Didier Lavanchy, high-speed digitizers manager, Keysight’s Communications Solutions Group. “With its newly developed technologies, such as the proprietary ICs, the U5310A ensures better measurement fidelity with higher resolution—thus allowing customers to see what they couldn’t see before”.

The averager (-AVG) firmware ensures accumulation of a large number of triggers for synchronous real-time sampling at 5 GS/s on two channels and 10 GS/s when interleaved. Innovative features, such as the unique programmable self-trigger output, optimizes the signal-to-noise ratio and increases the ability to measure very small peaks accurately.

This new PCIe high-speed digitizer focuses on interoperability, reusability and upgradability with other U53xxA digitizers. The U5310A’s software driver provides support for multiple programmable interfaces ensuring easy integration of the ADC card into existing environments.
