High-Speed Data Acquisition Made Simple: Introducing the ADQ3-USB Digitizer Series
Teledyne SP Devices has expanded its 12-bit ADQ3-series digitizer lineup with a powerful new addition: the ADQ3-USB.
Designed for high-performance data acquisition in compact, space-constrained environments, the ADQ3-USB brings the full capabilities of the ADQ3 platform into a stand-alone USB 3.2 form factor offering up to 10 Gigasamples-per-second (GSPS) sampling rate and 2 Gbyte/s sustained data transfer to a host PC.
Applications and Market Demand
High-speed digitizers are a critical component in analytical and sensing systems such as mass spectrometers, swept-source optical coherence tomography, LiDAR, automated test equipment, and distributed fiber optic sensing platforms. The demand for faster data acquisition in these fields is driven by a broader trend towards higher resolution, faster imaging speeds, and more granular real-time analysis. These use-cases generate gigabytes of data per second, demanding efficient real-time processing and high-speed data transfer. To preserve signal integrity, especially in compact and noise-sensitive environments, it is often essential to place the digitizer close to the detector within the system enclosure.
Compact Design and Performance
The ADQ3-USB is housed in a robust, fanless enclosure that supports side-by-side mounting of two units in a standard 1U 19" rack. This compact design allows users to place the digitizer close to the detector, minimizing cable length and reducing signal reflections, an essential factor for optimizing analog performance in high-speed applications.
It supports continuous data streaming at up to 2 Gbyte/s via USB 3.2, with onboard FPGA capabilities for real-time signal processing. Even large volumes of raw data up to 20 Gbyte/s can be efficiently reduced and transferred without bottlenecks. By eliminating the need for PCIe slots, the ADQ3-USB enables fast and simple integration with mini-PCs and laptops, making it suitable for mobile setups, embedded systems, and OEM applications.
Firmware and FPGA Options
One of the standout features of the ADQ3-USB is its support for multiple firmware packages tailored to specific application needs, including:
• FWDAQ for standard data acquisition
• FWATD for waveform averaging
• FWPD for pulse detection
• DEVDAQ for custom FPGA development
The open FPGA architecture allows users to implement application-specific algorithms directly on the digitizer, reducing the need for post-processing and enabling real-time decision-making.
OEM Integration and Model Variants
Teledyne SP Devices positions the ADQ3-USB for OEM integration, with ISO-certified production, global support, and tailored engineering services for hardware and firmware modifications.
The ADQ3-USB is compatible with a wide range of digitizer models within the ADQ3 series, including ADQ30, ADQ32, ADQ33, and ADQ35. Each model offers different sampling rates, bandwidths, and channel configurations. For example, the ADQ32-USB offers 2.5 GSPS sampling and 2.5 GHz bandwidth, while the ADQ35-USB supports up to 10 GSPS for ultra-fast applications.
Conclusion
The ADQ3-USB digitizer series represents a significant step in high-speed data acquisition technology. With its compact design, FPGA capabilities, and flexible integration options, it supports the development of faster and more efficient systems across laboratory, field, and production environments.

FLIR Si1-LD - Industrial Acoustic Imaging Camera for Compressed Air Leak Detection
The FLIR Si1-LD is an easy-to-use acoustic imaging camera for locating and quantifying pressurized leaks in compressed air systems. This lightweight, one-handed camera is designed to help maintenance, manufacturing, and engineering professionals identify air leaks faster than with traditional methods. Built with a carefully constructed array of MEMS microphones for high sensitivity, the Si1-LD produces a precise acoustic image that visually displays ultrasonic information, even in loud, industrial environments. The acoustic image is overlaid in real time on a digital image, allowing you to accurately pinpoint the source of the sound, with onboard analytics which quantify the losses being incurred. The Si1-LD features a plugin that enables you to import acoustic images to FLIR Thermal Studio suite for offline editing, analysis, and advanced report creation. Field analysis and reporting can also be done using the FLIR Acoustic Camera Viewer cloud service. Transferring of images can be managed via memory stick or USB data cable. Through a regular maintenance routine, the FLIR Si1-LD can help facilities reduce their environmental impact and save money on utility bills.
