["Description:\nbrand new and high quality\nSignal generator is a device that provides electrical signals at a variety of frequencies, square wave, and output levels.It is used as a signal source or excitation source for testing.Widely used in production practice and technology.\n\nFeatures:\nWith outer casing\nLCD high definition display\nSupport UART\nSupport frequency adjustment\nSupport duty cycle adjustment\nHigh precision detection\nSupport power-down memory function\n1-Channel PWM output\n\nFrequency set range:\nEnter the settings interface when short press any button FREQ+ or FREQ- in the normal running status to select frequency range.Automatically switch frequency range.\nPay attention to the position where the decimal point moves when the button is pressed.\nDisplay XXX.No decimal point,The minimum frequency is 1Hz.The frequency range is 1Hz ~ 999Hz.\nDisplay X.XX.The decimal point is the penultimate, The minimum frequency is 0.01KHz.The frequency range is 1.00KHz ~ 9.99KHz.\nDisplay XX.X.The decimal point is the third last,The minimum frequency is 0.1KHz.The frequency range is 10.0KHz ~ 99.9KHz.\nDisplay X.X.X.The decimal point is fully lit,The minimum frequency is 1KHz.The frequency range is 1KHz ~ 150KHz.\n\nFor example:\nDisplay 100 means PWM output frequency is 100Hz;\nDisplay 1.01 means PWM output frequency is 1.01KHz;\nDisplay 54.1 means PWM output frequency is 54.1KHz; \nDisplay 1.2.4 means PWM output frequency is 124KHz;\n\nDuty cycle set range:\nEnter the settings interface when short press any button DUTY+ or DUTY- in the normal running status to select duty cycle.Automatically switch frequency range.\nDuty cycle range is 0.00%-.\n\nUse steps:\nConnect to power supply;\nShort or long press button FREQ+ or FREQ- to set frequency;\nShort or long press button DUTY+ or DUTY- to set duty cycle\nConnect to load.\n\nUART communication and parameter settings:\nThe system supports UART data upload and parameter setting functions (TTL level);\nUART: 9600, 8, 1\n1.Set PWM frequency:\nF101 :Set frequency is 101Hz.101 can by replace by 001~999;\nF1.05 :Set frequency is 1.05KHz.1.05 can by replace by 1.00~9.99;\nF10.5:Set frequency is 10.5KHz.10.5 can by replace by 10.0~99.9;\nF1.0.5 :Set frequency is 105KHz.1.0.5 can by replace by 1.0.0~1.5.0;\n2.Set PWM duty cycle:\n DXXX :Set duty cycle is XXX. XXX can be 000-100.\nE.g:D051 means PWN duty cycle is be set as 51%.\n3.Read set parameter:\nSend read and then get parameter.\n4.Return value:\nReturn DOWN :Set success.\nReturn FALL :Set fail.\n\nApplication:\n1.Square wave signal generator, generating square wave signal for experimental development;\n2.Used to generate a square wave signal that controls the motor driver;\n3.Generate adjustable pulses for use by the MCU;\n4.Dimmer;\n5.Speed governor;\n\nNotice:\nIt's 1-channel PWM output signals are the same.They can not adjust independently. \n\nSpecification:\nProduct name: PWM Signal Generator\nWork voltage:DC 3.3V-30V\nFrequency range:1Hz~150KHz\nFrequency accuracy:2%\nDuty cycle range:0.00%-\nOutput Current:About 5-30mA\nOutput amplitude:Same to input voltage\nOperating temperature:-20℃~70℃\nMaterial: Plastic\nColor: Black\nSize:app. 78 x 26 x 42mm / 3.07 x 1.02 x 1.65in\nQuantity: 1 pc\n\nNote:\nTransition: 1cm=10mm=0.39inch\nNo retail package.\nPlease allow 1-2cm error due to manual measurement. pls make sure you do not mind before you bid.\nDue to the difference between different monitors, the picture may not reflect the actual color of the item. Thank you!\n\nPackage includes:\n1 x PWM Signal Generator(other accessories demo in the picture is not included.)"]
