Modular high-speed 32-channel digitizer offers highest available density

Keysight Technologies has introduced the M9709A 8-bit high-speed digitizer, providing 32 synchronous channels of 1GS/s sampling in a single module. The M9709A, the industry’s highest-density solution, is ideal for multichannel applications in advanced physics experiments such as hydrodynamics, plasma fusion (Tokamak/Stellarator), particle physics and microwave astronomy, says the company. The M9709A is a single-slot AXIe module, with 32 channels at 1GS/s sampling rate and 16 channels at 2GS/s when interleaved. The module can provide more than 500 MHz analog bandwidth. The digitizer also enables long acquisitions with its large on-board memory of up to 16GB. To ensure high throughput, the digitizer provides a four-lane (x4) PCI Express Gen 2 backplane, enabling sustained data transfer rates of up to 1.2GB/s. With four on-board Xilinx Virtex-6 FPGAs, the M9709A high-speed DAQ also optimizes measurement throughput and supports future customized implementations of high-performance data processing, says the company. “This new AXIe digitizer dramatically simplifies the creation of very dense data acquisition systems that include a large number of high-speed synchronous channels with a large set of full-scale range to maximize the user dynamic range,” said Pierre-François Maistre, R&D project manager, Keysight Software and Modular Solutions. “In advanced applications such as high-energy physics experiments, the M9709A provides excellent measurement fidelity from DC to 500 MHz analog bandwidth with up to 6.9 effective bits, 52dBc spurious-free dynamic range and 44dB signal-to-noise ratio, which unlock unique insight into your measurements."
