Function (waveform) signal generator. It can some periodic time function waveforms (sine wave, Fang Bo, triangle wave, saw tooth wave and wave, etc.), the frequency range can be from a few -he to tens of MHz function signal generator in the circuit experiment and equipment detection has a very wide range of uses. So the learning and design circuit will also be used to.DDS signal generator parameter: The frequency range of 1HZ-65534Hz is: DDS. ( no distortion, the enlarged part of the TL082)High speed () Fang Bo: 1MHZ or 2MHZ or 4MHZ or 8MHZ signalThe offset amplitude of the DDS signal can be adjusted by two potentiometerDDS signal: sine wave, square wave, saw tooth wave, reverse wave, triangle wave, ECG wave and noise wave.1602 LCD LCD screenIntuitive 5 keyboard.Step frequency: 1, 10,100,1000,10000HzAutomatically the last time after power supply.Offset: 0.5pp-5VppAmplitude: 0.5Vpp-14VppOutput impedance: ohms 20-200Power Supply:DC 9VPlug Type:EU Plug,it applies to Indonesia, , , , and so onVoltage:AC100-240Vcolor:As shownMaterial:plasticPackage Contents:1 x DDS function signal generatorOnly the above package content, other are not included.Note: Light reflection and different displays may cause the color of the item in the a little different from the real thing.
