Teledyne Digitizer

[Curtis Cassel]

Thedual-channel 12-bit digitizer supports synchronous sampling at 2.5 gigasamples per second (GS/s) on each channel and features an open Xilinx Kintex Ultrascale KU040 field-programmable gate array (FPGA). ADQ32 is streamlined for high-volume applications and is therefore suitable for integration by original equipment manufacturers (OEMs) in areas such as swept-source optical coherence tomography (SS-OCT), time-of-flight mass spectrometry (ToF MS), and distributed optical fiber sensing (DOFS).

Custom application-specific digital signal processing (DSP) can be performed in real-time in the on-board FPGA to characterize signals and extract valuable information. It can also be used to perform data reduction so that the output rate matches the 7 Gbyte/s sustained transfer capacity of the PCI Express interface. The data can then be post-processed either on the central processing unit (CPU) of the host PC, or transferred via peer-to-peer to a graphics processing unit (GPU).

This architecture offers great flexibility and allows the designer to use the most suitable type of processing resource for a given task. Examples of application-specific DSP include fast-Fourier transform (FFT) and k-space remapping for SS-OCT, and waveform averaging and zero suppression for ToF MS.

In addition to the high streaming rate and computational flexibility, the ADQ32 also offers excellent analog performance in terms of the effective number of bits (ENOB), spurious-free dynamic range (SFDR), and more. Hardware trigger, selection of internal/external clock, and general-purpose input/output (GPIO) simplify system-level integration. Please refer to the datasheet for full specifications.

Linkping, Sweden, October 25, 2019 - Teledyne SP Devices, a business unit of Teledyne Technologies Incorporated (NYSE: TDY), today announced the release of the ADQ7WB, a dual-channel 12-bit wideband digitizer with 6.5 GHz analog input bandwidth and 5 giga-sample per second (GSPS) sampling rate per channel. The wide instantaneous bandwidth and unprecedented dynamic performance combined with customizable real-time digital signal processing (DSP) and high data transfer rates makes it an ideal platform for satellite communication systems, radar, 5G, and more.

Direct RF Sampling and Multi-Band Support

ADQ7WB allows for direct sampling and transfer of intermediate frequency (IF) or radio frequency (RF) signals with up to 1 GHz instantaneous bandwidth within the frequency range 1 MHz to 6.5 GHz. This approach results in improved noise performance and lower cost as external mixers and local oscillators (LOs) are not needed. The intuitive digital down-converter firmware option can be configured to separate up to four individual IF/RF sub-bands and convert them to baseband for subsequent processing. One example of use is in Global Navigation Satellite System (GNSS) receivers which typically use three sub-bands with different center frequencies.

Optimized for Data Streaming and Computational Performance

In addition to the real-time onboard signal processing capabilities, ADQ7WB also supports continuous data streaming to the host PC or GPU. The GPU peer-to-peer streaming with rates of up to 7 Gbyte/s offers great flexibility to implement real-time signal processing either in the FPGA, GPU, or both. For spectrum monitoring applications, functions such as advanced frequency trigger can be implemented in the FPGA while the GPU is used for computationally intensive processing such as fast Fourier transforms (FFTs) with extreme resolution bandwidth. For applications requiring offline analysis, for example synthetic aperture radar (SAR) or spectrum recording, ADQ7WB also supports high-speed streaming to disk storage.

Dynamic Range Advantage

Teledyne SP Devices' products feature proprietary digital performance-enhancement technology that provides industry-leading spurious-free dynamic range (SFDR) performance. The ADX real-time error-correction IP operates in the background to remove unwanted performance-degrading artifacts in time-interleaved analog-to-digital converters (TIADCs). Time-interleaving is commonly used in many of today's ADCs and the built-in error-correction is often insufficient. ADX provides system-level performance beyond ADC datasheet specifications and therefore results in competitive advantages for our customers.

In this webinar, we delve into the advancements in digitizers for Swept-Source Optical Coherence Tomography (SS-OCT). Discover how these data acquisition boards are enabling deeper and wider imaging with higher resolution and faster scan rates.

At DSEI Japan, Teledyne SP Devices demonstrated an ADQ7 2-CH, 14-bit, PXIe digitizer that is continuously sending 5 Gigasamples per second via peer-to-peer streaming to an adjacent RADX Catalyst PXIe GPU that employs an NVIDIA Quadro T600 and is continuously performing 1 Megasample Fast Fourier Transforms on the incoming stream. The PXIe system employed in the demonstration included an NI PXIe-1095 chassis and an NI PXIe-8881 embedded controller running Ubuntu Linux 20.04. The demonstration shows that the peer-to-peer processing already available for PCIe applications, like computers and servers, is available for more industrial applications requiring PXIe interfaces.

ADQ7WB is a powerful 12-bit dual-channel digitizer designed for capturing RF signals up to 6.5 GHz. It excels in applications like radar, satellite monitoring, distributed fiber optic sensing, SS-OCT, and more. Here are a few highlights:

Watch the 2-minute video that shows how we achieved 28 Gbyte/s sustained data transfer from four ADQ32 digitizers to an NVIDIA RTX A2000 graphics processing unit (GPU). Peer-to-peer (P2P) technology enables direct transfers between the digitizers and GPU with little or no involvement of the central processing unit (CPU) or dynamic random-access memory (DRAM) on the host PC.

The PXD series digitizers include several software tools to allow engineers to quickly get started and to develop test software in LabView, CVI, Visual C++ or Visual Basic. PXD series software includes an IVI-scope compliant instrument driver, ActiveX control and a custom LeCroy PXD getting started application program for interactive control.

LeCroy, a founding member of the PXI Systems Alliance, has 20 years experience in the production of digitizers on a card and has been the market leader in such products, having built more than 400,000 channels of digitizers since 1980. These digitizers have won numerous awards, and included the model 6880 which was the first solid state 1 GS/s digitizer on a card. The LeCroy entry into the PXI digitizer market comes at a strategic time when two major vendors have halted production of their high performance VXI digitizers.
