Storage analog data

The microcomputer system chosen is based on the Pro-Log 8821 processor card which uses the Intel 8080A microprocessor. In addition, this card contains lk bytes of RAM memory and sockets for up to 4k bytes of EPROM memory containing the programs used in data collection and communication. The system also contains 32k bytes of RAM memory for data storage. Analog to digital... 

Data system. Components used to record and process information during the analysis of a sample. The system includes a computer and an analog-to-digital conversion module as well as other control devices for data recording, storage, and manipulation. 

The output of the NMR spectrometer must be transformed from an analog electrical signal into digital information that can be stored in the computer s dedicated computer. The minicomputers used in NMR spectroscopy have memory used for data accumulation, programs for manipulating the data, and storage devices to store large collections of data for future or additional manipulation into useful spectral results. 

The complete analytical system is under the control of a Motorola 6802 microprocessor. All switching of gas flows, timing, temperature control, error detection, analog to digital conversion, FID current measurement, signal Integration and manipulation, and data storage and transfer are controlled by this system. 

In the current apparatus, the TOF signal was displayed on a 400-MHz analog oscilloscope. The waveform from the screen was coupled into an IBM personal computer for data analysis and storage. In general, TOF experiments are carried out under single-shot measurements, which means that the single-event bandwidth of the oscilloscope must be much larger than l/t-p.
