1. Automation: The frequency value of the signal generator is divided into 4 ranges, automatic switching, high accuracy, and all parameters will be automatically saved after setting, so they will not be lost when the power is off. 2. Prevent Malfunction: The signal generator has a lock function to prevent malfunction and ensure that the value you set is not easily changed. 3. LCD Display: The signal generator has an LCD display, which shows the frequency and duty cycle value, and the reading is very convenient. 4. Strong Function: The signal generator has a PWM output function, frequency and duty cycle can be set separately by buttons and supports serial communication. 5. Wide Application: The signal generator can be used as a square wave signal generator for experimental development and motor drivers, and can also be used as an adjustable pulse generator for MCUs, control related circuits. Item Type: Signal Generator Material: ABS Working Environment Temperature: -20-70 ℃ Working Voltage Range: DC 3.3V-30V Frequency Range: 1Hz-150kHz Output Current: 5-30 mA Duty Cycle Range: 0-100%
