In some instruments, such as framing camera, the hardcore is ICCD that is built on the contrivance. And as a result, the camera is able to output more stable signal in terms of super high-speed photography. Besides, another indispensable application is as a component of an accelerator. And in this case, the accelerator can precisely control several clusters through it. For the above application, the invention consists of a few parts: TTL-NIM level conversion circuit, input signal delay device, pulse generator, and mixer. When a sinusoidal signal is input, the accelerator timer will generate a synchronized frequency signal that is TTL level. And then it will be converted to NIM level by TTL-NIM and then delayed. The delayed signal will enter the pulse generator that can adjust its pulse width within a certain range, and eventually output a gate signal that people want, and then enter the mixer to combine with the original signal to modulate the original signal. So with the invention, people can easily modulate the pulse width and extension time of the input sinusoidal signal within the allowable range. 1AAAkAAA SG DBM TTL-NIMfrev trigger Timing signal TD4V Pulse generator Figure 1 Figure 2 1
