Multi-Channel 10-bit Digitizer with up to 4 GS/s Sampling Rate

12 October 2020 - Teledyne SP Devices announced the release of ADQ8-4X – a modular data acquisition board with configurable channel count and sampling rate. The product complements the previously released ADQ8-8C by offering a higher sampling rate and software-selectable two- or four-channel mode of operation. The high channel density, flexible mode of operation, and open FPGA architecture make it ideal for large-scale physics installations and Original Equipment Manufacturer (OEM) product integration.

The programmable analog front-end (AFE) supports multi-purpose operation and can therefore be used with a wide variety of detectors and in applications such as particle physics, scientific instruments, time-of-flight applications, and more. Jan-Erik Eklund, Digitizer Product Manager at Teledyne SP Devices, commented, “ADQ8-4X extends our 10-bit product portfolio by offering a flexible analog front-end and faster sampling at two different rates. This helps our customers optimize channel count, sampling rate, and cost.”

When built on SP Devices’ digitizers, large multi-channel systems can consist of a combination of different digitizer models and can perform simultaneous acquisitions on a large number of channels distributed over many chassis with a timing alignment of better than 200 picoseconds. Now, with the new ADQ8-4X, these systems can be extended gradually over time.

Additional capabilities include:

• AFE with programmable channel count, sampling rate, DC-offset, and input voltage range
• 10 bits resolution with 2 GS/s sampling rate in 4-channel mode and 4 GS/s in 2-channel mode
• 1 GHz analog input bandwidth
• Open Xilinx FPGA with resources available for customized real-time digital signal processing
• 1 Gbyte onboard acquisition memory
• Hardware trigger and highly accurate multi-channel synchronization capabilities
• Extensive software suite including easy-to-use evaluation/integration software Digitizer Studio
• Available in PXI Express
