High - speed analog - to - digital conversion chips can thus exploit hundreds of megahertz of rf spectrum simultaneously 高速类比数位转换晶片因此能同时运用数亿赫兹的rf频谱。
The delay chip , whose delay precision can be 10ps , wide band sample - hold amplifier ( sha ) , and high speed and precise analog / digital conversion ( adc ) are used in the system 能够对5mhz以下的信号进行随机采样、波形显示、频谱分析,还能够对采集的波形数据进行存储、共享。
