We report the early development of a multifunctional digital transceiver built on a Field-Programmable Gate Array (FPGA). The multifunctional transceiver not only offers the functionalities of a conventional transceiver and pulse sequencer, but also is capable of combining frequency detection and compensation, inline data correction and image reconstruction. We describe the design and implementation of the multifunctional transceiver and demonstrate its capabilities of image acquisition and reconstruction with real-time frequency and phase compensation.
