校準(zhǔn)自檢車載精密參考電壓允許在系統(tǒng)運行期間對ADC和模擬輸出通道進行校準(zhǔn)、驗證和自動校準(zhǔn)。VMIVME-3111板上的參考電壓為跳線選擇，標(biāo)稱范圍為±2.5 VDC、±5 VDC或±10 VDC。將實際電壓調(diào)整為低于其標(biāo)稱值約0.49%，以產(chǎn)生低于滿量程10（0A HEX）計數(shù)的全量程讀數(shù)。這樣做是為了盡量減少不明確的“刻度結(jié)束”讀數(shù)的發(fā)生。執(zhí)行自動校準(zhǔn)VMIVME-3111板實現(xiàn)兩個鎖存12位數(shù)模轉(zhuǎn)換器（DAC）。一個DAC調(diào)整信道零偏移，而另一個DAC則調(diào)整信道增益。兩個DAC都接受右對齊的12位數(shù)據(jù)，并且都是只讀設(shè)備。為了進行實際校準(zhǔn)，我們建議采用圖4.8.2-1和4.8.2-2所示的逐次逼近方法。該自動校準(zhǔn)程序應(yīng)始終在通電或系統(tǒng)復(fù)位后執(zhí)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.
