  • 1HZ-500KHZ DDS Functional Signal Generator, Seesii DDS Function Low Frequency Signal Generator Sine/Triangle/Square/Sawtooth Waveform
    Bestseller #1
    1HZ-500KHZ DDS Functional Signal Generator, Seesii DDS Function Low Frequency Signal Generator Sine/Triangle/Square/Sawtooth Waveform (200)
      1HZ-500KHZ DDS signal generator is small but has many functions, easy to operate and carry. The power supply can be either AC/DC adaptor or a battery. It can be used with oscilloscope to test and debug electronic circuit, the frequency response of audio amplifier and impulse response,It also can calibrate the sweep time factor of oscilloscope. The square waveform is suitable for oscilloscope attenuator and the adjustment of probe impulse response. Have a filter (can be opened and closed) to suit the output of sine wave and pulse wave. This functional signal generator can test many kinds of wave forms such as: sine, square, triangle, positive and negative sawtooth waveform. It is especially designed for those professional worker.
