本文描述一个紧湊轻便的脈冲发生器,它的重复频率高,输出脈冲在毫微秒范围内。重复频率可高至10兆週;脈冲上升时间小于2.5豪微秒。脈宽可调,其范围自2.5至25毫微秒。输出脈冲极性为负,并且幅度在0—12伏之间可调。输出阻抗为125欧。此仪器有电子门控制输出、单脈冲输出以及由一外信号源触发设备。 This article describes a compact, lightweight pulse generator that has a high repetition rate and output pulses in the nanosecond range. Repetition frequency can be as high as 10 trillion weeks; pulse rise time less than 2.5 Hao microseconds. Pulse width adjustable, ranging from 2.5 to 25 ns. The polarity of the output pulse is negative and the amplitude is adjustable between 0 and 12 volts. The output impedance is 125 ohms. The instrument has electronic gate control output, single pulse output and trigger signal from an external device.
