校准自检车载精密参考电压允许在系统运行期间对ADC和模拟输出通道进行校准、验证和自动校准。VMIVME-3111板上的参考电压为跳线选择,标称范围为±2.5 VDC、±5 VDC或±10 VDC。将实际电压调整为低于其标称值约0.49%,以产生低于满量程10(0A HEX)计数的全量程读数。这样做是为了尽量减少不明确的“刻度结束”读数的发生。执行自动校准VMIVME-3111板实现两个锁存12位数模转换器(DAC)。一个DAC调整信道零偏移,而另一个DAC则调整信道增益。两个DAC都接受右对齐的12位数据,并且都是只读设备。为了进行实际校准,我们建议采用图4.8.2-1和4.8.2-2所示的逐次逼近方法。该自动校准程序应始终在通电或系统复位后执行。
Calibration Self-Testing On-board precision reference voltages permit calibration, verification, and autocalibration of the ADC and the analog output channels during system operation. Reference voltages on the VMIVME-3111 board are jumper-selected for nominal ranges of as ±2.5 VDC, ±5 VDC, or ±10 VDC. The actual voltages are adjusted to be approximately 0.49 percent below their nominal values in order to produce full-range readings which are 10 (0A HEX) counts below full-scale. This is done in order to minimize the occurrence of ambiguous "end-of-scale" readings.Performing Autocalibration The VMIVME-3111 board implements two latching 12-bit Digital-to-Analog Converters (DACs). One DAC adjusts the channel zero offset, while the other adjusts the channel gain. Both of the DACs accept right-justified 12-bit data and are write-only devices. To do the actual calibration, we suggest the method of successive approximation shown in Figures 4.8.2-1 and 4.8.2-2. This autocalibration routine should always be performed after a power up or a system reset.
