Abstract :
A superconducting digital-RF receiver with high-ingest-rate data recording capability has been developed. The data recorder unit uses standard PC components with state-of-the-art solid-state drives (SSDs) and interfaces with the superconductor analog-to-digital converter (ADC) through a commercial FPGA board. High-speed data ingest rates exceeding 3.2 Gbps have been demonstrated successfully with single-bit ADCs clocked up to 27.52 GHz. A continuous recording of 2.5 TB has been achieved using a bank of 12 SSDs. A new graphical user interface featuring single button operation and automatic file naming, as well as convenient configuration setting, has been developed.
