12-Bit PXIe wideband digital receiver runs at up to 3.2GS/s

The M9203A PXIe 12-bit high-speed digitiser/wideband digital receiver from Keysight Technologies runs at up to 3.2GS/s, with up to 2GHz instantaneous analogue bandwidth. The high-speed digitiser is ideal for applications in wireless communication, emerging communication standards, radar and satellite communication and semiconductor automated test.

As a component of a Keysight solution, this wideband digital receiver allows microwaves measurements. These modular solutions are highly adaptable and integrate core signal-analysis capabilities with hardware speed and accuracy, allowing engineers to tailor the systems to fit their specific needs.

“The M9203A PXIe 12-bit wideband digital receiver is ideal when embedded in a larger system or as a component of a Keysight Reference Solution,” said Jean-Luc Lehmann, high-speed digitisers product manager, Keysight’s Communications Solutions Group. “Its performance allows wideband signal capture and its scalability enables system expansion.”

The M9203A features a large FPGA that can implement different functionalities depending on the selected firmware option, such as:

    * Custom firmware capability (-FDK) supporting the deployment of custom processing algorithm with the U5340A FPGA development kit. Integrating algorithms minimises the need for additional circuitry and exploit the full density and speed of the digitiser.

  • Triggered simultaneous acquisition and readout (-TSR),allowing sustained triggered acquisitions of thousands of samples at hundreds of kHz rates without missing any events.
  • Wideband real-time digital down-conversion (-DDC)on each channels, enabling the user to tune and zoom on the signals of interest. The filters and local oscillators (LO) are fully synchronised allowing phase-coherent post processing.

 

Custom functions can also be implemented on-board, providing support of various application bundles, such as:

  • Digital down-conversion streaming and recording (-CB2), allowing users to capture and record a long duration of large frequency bands up to 320MHz instantaneous bandwidth (IBW) on a single channel, or up to 200 MHz IBW on two phase coherent channels.
  • Digitiser streaming and recording (-CB0), enabling to record the raw acquisition data.
  • High fidelity digitiser (-BB1), providing enhanced performance by compensating the analogue-to-digital converter (ADC) and the front-end distortion, minimising the interleaves spurs and reducing the overall noise bandwidth.
