Features: *Signal generator, 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. *High definition LCD display *1-Channel PWM output. *Support frequency adjustment and duty cycle adjustment; *Wide frequency range and high accuracy. *Support Serial Communication. *Widely used in production practice and technology. Specification: *Work voltage:DC 3.3V-30V *Frequency range:1Hz~150KHz *Frequency accuracy:2% *Duty cycle range:0.00%-100% *Output Current:About 5-30mA *Output amplitude:Same to input voltage *Size:approx. 79*43*27mm *Operating temperature:-20degree Celsius~70degree Celsius 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 switch 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. 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; 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.Automatically switch frequency range. Duty cycle range is 0.00%-100%. Application: *Square wave signal generator, generating square wave signal for experimental development; *Used to generate a square wave signal that controls the motor driver; *Generate adjustable pulses for use by the MCU; *Dimmer; *Speed governor Use steps: 1.Connect to power supply; 2.Short or long press button 'FREQ+' or 'FREQ-' to set frequency; 3.Short or long press button 'DUTY+' or 'DUTY-' to set duty cycle; 4.Connect to load.
