1HZ~150KHZ Signal Generator Digital Display PWM Pulse Frequency Duty Ratio Adjustable Square Wave Rectangular Signal Generator

1HZ~150KHZ Signal Generator Digital Display PWM Pulse Frequency Duty Ratio Adjustable Square Wave Rectangular Signal Generator leírása

For example:Display '100' means PWM output frequency is 100Hz;Display '1.01' means PWM output frequency is 1.01KHz;Display '54.1' means PWM output frequency is 54.1KHz;Display '1.2.4' means PWM output frequency is 124KHz;
Set PWM frequency:'F101':Set frequency is 101Hz.'101' can by replace by 001~999;'F1.05':Set frequency is 1.05KHz.'1.05' can by replace by 1.00~9.99;'F10.5':Set frequency is 10.5KHz.'10.5' can by replace by 10.0~99.9;'F1.0.5':Set frequency is 105KHz.'1.0.5' can by replace by 1.0.0~1.5.0;
Frequency set range:Enter the settings interface when short press any button 'FREQ+' or 'FREQ-' in the normal running status to select frequency range.Automatically frequency range.Pay attention to the position where the decimal point moves when the button is pressed.Display 'XXX'.
No decimal point,The minimum frequency is 1Hz.The frequency range is 1Hz ~ 999Hz.Display 'X.XX'.The decimal point is the penultimate, The minimum frequency is 0.01KHz.The frequency range is 1.00KHz ~ 9.99KHz.Display 'XX.X'.The decimal point is the third last,The minimum frequency is 0.1KHz.The frequency range is 10.0KHz ~ 99.9KHz.Display 'X.X.X'.The decimal point is fully lit,The minimum frequency is 1KHz.The frequency range is 1KHz ~ 150KHz.
Duty cycle set range:Enter the settings interface when short press any button 'DUTY+' or 'DUTY-' in the normal running status to select duty cycle.Automaticallyswitch frequency range.Duty cycle range is 0.00%-.
Use steps:Connect to power supply;Short or long press button 'FREQ+' or 'FREQ-' to set frequency;Short or long press button 'DUTY+' or 'DUTY-' to set duty cycle;Connect to load.UART communication and parameter settingsThe system supports UART data upload and parameter setting functions (TTL level);
UART: 9600, 8, 1
