KNACRO Dual Channel co Frequency Pulse Signal Generator Independent Duty Cycle Adjustable Square Wave Rectangular Signal Generator

Setting process: 1. Press the SET button. The frequency parameter flashes. Set the frequency with the UP or DOWN keys. Press and hold the UP key. The DOWN key can quickly increase or decrease. 2. Press the SET button. The duty cycle parameter flashes. Set the duty cycle using the UP or DOWN keys. Press and hold the UP key. The DOWN and DOWN keys can quickly increase or decrease. 3. Press the SET button to exit the setting. 4. The data is automatically memorized, and all setting parameters are saved and saved. 5. In the normal display mode, use the UP button or DOWN button to switch the two PWM values, The indicator light indicates the PWM1 setting value, and the indicator light off indicates the PWM2 setting value. Operating voltage: 4V~30V Frequency range: 1Hz~160KHz Frequency accuracy: 2% Signal load capacity: output current 5~30mA Output amplitude: The amplitude is equal to the working voltage. PWM output, can set the frequency, duty cycle The frequency is divided into four ranges, automatic switching: 1.XXX (without decimal point): 1Hz~999Hz, unit 1Hz 2.X.XX (decimal point in hundreds): Value is from 1.00KHz to 9.99KHz in 0.01KHz 3.XX.X (decimal point in ten digits): The value is 10.0KHz~99.9KHz, the unit is 0.1KHz 4.X.X.X. (full decimal point): Value 100KHz~160KHz, unit 1KHz E.g: 100 represents 100Hz 1.00 means 1.00KHz 10.0 means 10KHz 1.0.0. means 100Khz 1. It is used as a square wave signal generator to generate square wave signals for development and use. 2. Used to generate a square wave signal that drives a stepper motor driver. 3. Generate adjustable pulses for use by the MCU. 4 Produce adjustable pulses to control the associated circuitry.
