Feature: 1. This signal generator provides electrical signals at various frequencies, square wave, pulse, and output levels. It supports dual mode: PWM mode and PULSE mode, which can be switched at any time. It serves as a signal source or excitation source for testing and is widely used in production and technical applications. 2. Two modes are available: - PWM mode: continuous frequency and duty cycle adjustment; pulse number is not adjustable; continuously outputs waveform. - PULSE mode: adjustable positive pulse width, negative pulse width, delay start time, and number of pulses. 3. Can be used with drivers to enable dimming, speed control, solenoid valve control, and other functions. 4. Wide input voltage range: 3.3V30V, includes reverse polarity protection, and features 5.08mm terminal wiring.
