- Abstract
At present, Intermediate frequency(IF) broadband signals are widely used in the fields of communication and radar. In order to reprocess the signals that cannot be processed in real time and reproduce the collected signals in other locations, an IF broadband signal acquisition, storage and playback system was designed. Based on the system structure of FPGA(field-programmable gate array) + ADC(analog-to-digital converter) / DAC(digital-to-analog converter), the intermediate frequency wideband signal was collected and transmitted to the host computer through PCIE for storage, and then sent to DACfor playback through PCIE(peripheral component interconnect express), thus completing the collection, storage and playback of the signal, which had high universality and portability. The intermediate frequency signals could be acquired,stored and played back with a bandwidth of 400 M at a sampling rate of 1 G, by which the requirements of the acquisition,training and storage and playback system could be fully met in high-speed broadband signal acquisition equipment.
