利用Z-80微处理机组成非闭环的负反馈自动匀场单元,实现了对F×90Q谱仪分辨率的自动调整和控制,分辨率稳定度达0.10Hz。适合各类PFT谱仪进行长时期累加实验。
The Z-80 microprocessor is used to form the non-closed loop negative feedback automatic shimming unit, which can automatically adjust and control the resolution of the F × 90Q spectrometer. The resolution stability is up to 0.10Hz. Suitable for all kinds of PFT spectrometer for a long period of accumulation experiments.
