In-line reflecting time-of-flight mass spectrometer for molecular structural analysis using collision induced dissociation

A real-time control system for use with an NMR spectrometer. The control system comprises a control section, a plurality of functional units controlled by the control section, and a bus line connecting the control section with the functional units. Each functional unit has a memory storing event data specifying the conditions of control means such as gates included in the functional unit. The control section has a memory storing timing data and event codes specifying event data. The control section successively produces timing signals and event codes according to the timing data. The timing signals are transmitted to the functional units over the bus. Each functional unit reads event data from its memory according to the incoming event codes and controls its gates according to the event data in synchronism with the timing signals.
