Problems solved by technology

Large size, inconvenient control, poor consistency and synchronization

[0005] Among the existing technical solutions, the integrated solution has narrow effective signal bandwidth and obvious SINC roll-off effect, which affects the characteristics of broadband signal indicators, covers a small frequency range, and is inconvenient to call the full-parameter serial port control method; the discrete solution is not integrated enough, and the volume is too large. Inconvenient control, poor consistency and synchronization
