AI Technical Summary
Existing radio interference signal generation technologies struggle to generate high-bandwidth, high-frequency, and multi-channel analog signals, and the integration of development tools increases the complexity of chip development.
The system adopts an ARM:STM32F417ZGT6 main control chip + FPGA + DAC hardware architecture. It uses the FPGA as the digital processing core and is equipped with a high-bandwidth, high-sampling-rate AD9371 digital-to-analog converter chip. The AD9371 is extended through the multiplexer and gating logic inside the FPGA to realize the generation of multiple channels and various types of digital modulation signals in the frequency band of 300MHz to 6GHz.
It enables the generation of high-bandwidth, high-frequency multi-channel analog signals, supports multiple modulation methods, and ensures signal consistency and independent control by extending AD9371 through FPGA without significant code modifications.
