It was satisfied for performance testing of high - speed a / d circuit in the project assess the factors of reducing a high speed a / d circuit performance were found out, such as harmonic distorted in front analog circuit, . sample clock shaking, analog power and the noise in ground plane etc
並在試驗測試的基礎上找出了影響高速模數轉換電路轉換性能的幾個主要的因素，即：前端運放電路諧波失真、采樣時鐘抖動、模數電源及共地噪聲串擾等。The adc aperture jitter must be minimal, and the sampling clock generated from a low phase - noise quartz crystal oscillator
Adc的孔徑抖動必需盡可能的小，而且要使用低相位噪聲的石英晶體振蕩器作為采樣時鐘發生器。The radio frequency receiver supports interface for instrument and base station and air interface for mobile station, and it takes the task of magnifying low noise and down - convert and digital baseband processor filtering and magnifying intermediate frequency to reverse link signal. the digital baseband processor samples the received signal after down - convert radio frequency signal to intermediate frequency signal and processes other processing and supports interfaces to computer, next sends data to computer. the gps receiver supports interface for instrument and gps system, and receives gps system signal, next it demodulates the correlative information and sends out benchmark clock signal we need
射頻接收部分主要為儀器和基站、移動臺提供空中介面，其主要任務是在反向鏈路上對接收到的射頻調制信號進行低噪聲放大、射頻下變頻變換、中頻濾波放大等;數字基帶部分為對接收信號變頻為中頻后進行a / d采樣，以及其他的rsp處理並和計算機提供介面，將數據送至計算機進行后臺處理、顯示等; gps接收機部分為儀器和gps系統提供介面，接收gps系統信號並解調相關信息，輸出所需的電文及時鐘基準信息等。
