本函数信号发生器能同时产生A、B两路信号，并且两路信号能分别进行参数设置，使用【通道切换】按键进行切换，进而输出不同频率、幅值、占空比和直流偏置的信号。本信号发生器能输出的信号有方波(F)、正弦波(Z)、三角波(S)、锯齿波(J)，频率范围为0.01Hz-1MHz。(The function generator can generate two signals of A and B at the same time, and the two signals can be set up separately, and switch by using [channel switch] button, and then output signals with different frequency, amplitude, duty cycle and DC bias. The signals that the signal generator can output are Fang Bo (F), sine wave (Z), triangular wave (S), and sawtooth wave (J), and the frequency range is 0.01Hz-1MHz.)
