增益带宽积 meaning in Chinese

gain bandwidth product
gb product

Firstly , the system has a good snr and high accuracy , which is owed to wideband operational amplifier being used , accurate adjustment by da , 12 - bit high sampling ad converter being applied . secondly , data transmission becomes less by using forecasting code technology and dictionary compress technology , which are run by dsp on board
本采集系统采用400mhz增益带宽积的运算放大器，运用da高精度校准技术，并选用高采样率低噪声的12位ad转换芯片进行模拟电路和ad转换电路设计，既保证了数据采集系统的信噪比，又提高了系统测量精度。
