Wideband 12-bit digital receiver: low noise in PXIe format
The M9203A PXIe 12-bit high-speed digitiser/wideband digital receiver runs at up to 3.2 Gsamples/sec, with up to 2 GHz instantaneous analogue bandwidth. This high-speed digitiser is proposed for applications in wireless communication, emerging communication standards, radar and satellite communication and semiconductor automated test. As a component of a Keysight PXIe configuration, this wideband digital receiver allows microwaves measurements.
The M9203A features a large FPGA that can implement different functionalities – reprogrammable functions implemented in hardware – 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 exploits the full density and speed of the digitizer.
– 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 channel, 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 320 MHz instantaneous bandwidth (IBW) on a single channel, or up to 200 MHz IBW on two phase coherent channels.
– Digitiser streaming and recording (-CB0), enabling recording of 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.
