Since the measurement initiation is controlled by the leading slope of the pulse, part of the pulse is lost and the resulting spectrum is distorted unless some pretrigger delay is specified.
因为测量的引发是由脉冲的前导沿控制的，除非设置一定的预触发延迟，否则会丢失部分脉冲、造成频谱失真。

Unique technology called Vapor pulse Coagulation (VPC), which produces faster, more uniform results with pulsed energy instantly delivered in a controlled manner.
Stepper motor is a motor controlled by digital signal, which converts pulse signal into Angle displacement. The wheeling speed is controlled by the frequency of pulse signal.
