PCIe high-speed digitizer captures 10 Gsample/sec at 10-bit

June 01, 2016 // By Graham Prophet
Keysight says it has a unique digitizer product that packs high performance in a very small form factor, for applications requiring a high sampling rate and a large bandwidth, such as medical research, MS-TOF, LiDAR, NDT and DSTS.

The U5310A 10-bit PCIe high-speed digitizer runs at 10 Gsamples/sec. 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 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). It can be used for advanced physics experiments using single-shot or event-based applications. And features two channels with 10-bit resolution, simultaneous sampling at up to 5 Gsample/sec (10 Gsample/sec 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, requiring a 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 fsec jitter. This specific IC drives the two ADCs, minimizing jitter. Moreover, the TRAC trigger IC provides time precision of 15 psec RMS.


The averager (-AVG) firmware ensures accumulation of a large number of triggers for synchronous real-time sampling at 5 or 10 Gsample/sec. Features such as the unique programmable self-trigger output optimize the signal-to-noise ratio and increase the ability to measure very small peaks accurately. The U5310A’s software driver provides support for multiple programmable interfaces ensuring easy integration of the ADC card into existing environments.
