DHF-1型可调相位多功能函数发生器的所有波形的频率、相位、波形正负斜率以及脉冲宽度都是连续可调的.它能产生正弦、矩形、三角、梯形、正负锯齿等连续波形;还能产生斜波、阶跃波和正负斜率、脉冲宽度可独立调谐的单周期任意波.多功能函数发生器如同程序机那样,是为土动三轴团环伺服控制试验系统设计研制而成的.在下列试验程序中有特殊的作用:拉力试验、断裂力学、低周疫劳、疲劳、应力缓和、蠕变、高速冲击和振动等试验.
DHF-1 adjustable phase multi-function generator of all waveform frequency, phase, waveform positive and negative slope and pulse width are continuously adjustable. It can produce sine, rectangle, triangle, trapezoid, positive and negative sawtooth continuous Waveform, but also generate a ramp, step wave and positive and negative slope, the pulse width can be independently tuned single-cycle arbitrary wave .Multifunctional function generator, as the programmer, is designed for soil moving triaxial ring servo control test system design Developed in the following test procedures have a special role: tensile test, fracture mechanics, low weeks of fatigue, fatigue, stress relaxation, creep, high-speed impact and vibration tests.
