产品详细资料
为了为测试和校准双极范围提供正参考和负参考,CAL TEST电压被路由到自检多路复用器的HIGH(非反相)和LOW(反相)输入端。3.9.4增益自动校准如图3.9.4-1所示,通过调整ADC的参考输入实现增益自动校准。12位自动增益DAC的输出被偏置和衰减,以产生±1.2%的增益调整范围,对应于每个DAC LSB 0.0006%的调整分辨率。增益DAC的控制数据被写入位于VMIVME-3111分配的地址空间中的相对地址0A(HEX)处的16位“仅写”寄存器中,为12位,右对齐。3.9.5零自动校准在任何高增益、直接耦合的信号路径中,输入端的零偏移误差与路径增益相乘,因此可能产生较大的输出误差。因此,VMIVME-3111中的零自动校准在可编程增益放大器(PGA)的输入端执行。
To provide both positive and negative references for testing and calibrating bipolar ranges, the CAL TEST voltage is routed to both the HIGH (noninverting) and LOW (inverting) inputs of the self-test multiplexer. 3.9.4 Gain Autocalibration As shown in Figure 3.9.4-1, gain autocalibration is implemented by adjusting the reference input of the ADC. The output of the 12-bit autogain DAC is offset and attenuated to produce a gain adjustment range of ±1.2 percent which corresponds to an adjustment resolution of 0.0006 percent per DAC LSB. Control data for the gain DAC is written as 12 bits, right-justified, into a 16-bit WRITE ONLY register located at relative address 0A (HEX) in the VMIVME-3111 assigned address space. 3.9.5 Zero Autocalibration In any high-gain, direct coupled, signal path, zero offset errors at the input are multiplied by the path gain and can, therefore, produce large output errors. For this reason, zero autocalibration in the VMIVME-3111 is performed at the input to the Programmable Gain Amplifier (PGA).
