| 英文摘要 | A CPLD-based long-duration pulse generator, which can generate singular or continuous pulse with ultra-low repetition rate/long cycle, is introduced in this paper. The cycle (T) of output pulses generated by this generator can be selected in a range from Tmin=1 ms to Tmin>1000 s. Also, the width of the output pulse can be adjusted from 1/1000 cycle to 999/1000 cycle stepped by 1/1000 cycle. Accuracy of the repetition rate (f) of output pulses is less than or equal 0.02 [per mille] , and the long-term instability is within ±0.01 [per mille] . There are two modes selectable for output pulses, singular pulse output and repetitive pulse output, which can be set by a two-position switch. When the singular pulse output mode is selected, only one pulse can be generated each time by pressing an external control push-button. This pulser can provide both TTL/T over-bar T over-bar L over-bar output signals and NIM/N over-bar I over-bar M over-bar output signals. The rise time of the NIM output signal is tr less than or equal 4 ns and the fall time is tf less than or equal 4 ns. We use CPLD to construct the main circuits. Compared with the circuits constructed by TTL devices, the new pulse generator has features such as less components, lower cost and lower dissipation. |
