Features:  The module is powered by 5V Type-C, the user can select the desired chip, set the desired point frequency, sweeping starts frequency, sweeping stop frequency, and the sweeping-step frequency.  You can set the clock reference frequency and change the output waveform signal. When connecting to an external clock, you need to input the corresponding external clock frequency.  In Waveform, you can output Sine (sinewave) signal, Square (squarewave) signal, Triangular (triangularwave) Signal.  In the main interface, you can select Point (point frequency) output mode, Sweeping (sweeping frequency) output mode, and Stop (stop) output mode.  The module supports PC control, and the PC control operation is the same as the full-screen touching screen operation.  The plug-and-play operation is simple and easy to carry, and it can also realize point frequency and sweeping frequency work, and full touching screen operation.    Specifications:  Name: Signal Generator  Material: printed circuit board  Power supplys: DC5V  resolution bit: 10  Output frequency ranges: ≤3MHz  Output amplitude: about 0.6Vpp sinewave and triangular waves; about 3Vpp square waves  Output impedance: 200ohm  Output interface: SMA  Output channel: 1 channel  Item size: 103 * 63 * 17mm / 4.06 * 2.48 * 0.67in  Item weight: 89g / 3.14ounce  Package size: 125 * 103 * 40mm / 4.92 * 4.06 * 1.57in  Package weight: 116g / 4.09ounce    Packing List:  1 * Signal Generator  1 * Type-C Cable
