An analytical scientific instrument with microcomputers to control the collection, conversion, and recording of data. For example, a microcomputer can control scanning in spectrographic devices like spectrometers and Fourier interferometers, automatically adjust sensors and transducers for out-of-limit conditions, compensate collected data for automatic gain adjustments, average collected data,transform data using processes like fast Fourier transform, convert data to engineering units and provide formatted printouts.; 帶有微型計(jì)算機(jī)的科學(xué)分析儀器,微機(jī)用來控制數(shù)據(jù)的采集、轉(zhuǎn)換和記錄。例如,微型計(jì)算機(jī) 能控制攝譜設(shè)備(如分光儀器和傅里葉干涉儀)中的掃描,在越界條件下,自動(dòng)調(diào)整傳感器和變 換器,對采集的數(shù)據(jù)進(jìn)行補(bǔ)償以便進(jìn)行自動(dòng)增益調(diào)節(jié),對采集 的數(shù)據(jù)取平均值,利用諸如快速傅里葉變換的過程來變換數(shù)據(jù),把數(shù)據(jù)轉(zhuǎn)換成工程單位和提供 格式化打印輸出等。
