32–ch, high-speed AXIe digitiser offers high-density modular measurements

May 05, 2015 // By Graham Prophet
For applications that include research work such as high-energy advanced physics, Keysight Technologies’ M9709A 8-bit high-speed digitiser, provides 32 synchronous channels of 1 Gsample/sec sampling in a single module.

The M9709A is a single-slot AXIe module, with 32 channels at 1 Gsample/sec sampling rate and 16 channels at 2 Gsample/sec when interleaved. The module can provide more than 500 MHz analogue bandwidth. The digitiser 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/sec. With four on-board Xilinx Virtex-6 FPGAs, the M9709A 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 maximise 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 ratio, which unlock unique insight into your measurements.”

The M9709A AXIe digitiser extends Keysight’s portfolio of AXIe based modular products. With an option of several AXIe chassis (2- or 5-slot), the module provides a fully operational system of up to 96 channels depending on the chassis configuration.
