The digitiser is a single-slot AXIe module, with 32 channels at 1 GS/s sampling rate and 16 channels at 2 GS/s when interleaved. The module can provide more than 500 MHz analogue bandwidth. It also enables long acquisitions with its very large on-board memory of up to 16 GB.
To ensure high throughput, the digitiser provides a four-lane (x4) PCI Express Gen 2 backplane, enabling sustained data transfer rates of up to 1.2 GB/s. With four on-board Xilinx Virtex-6 FPGAs, the high-speed DAQ also optimises measurement throughput and supports future customised implementations of high-performance data processing.
“This new AXIe digitiser 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 analogue bandwidth with up to 6.9 effective bits, 52 dBc spurious-free dynamic range and 44 dB signal-to-noise ratios.”
