Tips: PWM Signal Generator vs. Function Signal Generator

A PWM Signal Generator is designed for precise control of Pulse Width Modulation signals, commonly used in applications like motor control and power supplies. It produces digital output with adjustable parameters for pulse width and frequency, offering efficient power control in devices.

On the other hand, a function signal generator is a versatile tool producing various analog waveforms like sine, square, triangle, and sawtooth. It is employed in testing, calibration, and educational settings, allowing users to adjust frequency, amplitude, and waveform type.

The crucial distinction lies in their primary functions: PWM generators are specialized for power control with digital output, while function signal generators offer versatility in generating analog waveforms for broader electronic applications. Choosing between them depends on the specific needs of the application, whether it requires precise digital control through PWM or a range of analog waveforms for testing and educational purposes.

A signal generator is a versatile tool used to generate electrical signals of varying frequencies, amplitudes, and waveforms. It is often used to test and troubleshoot electronic circuits. In this video, it will be demonstrated how to accurately measure voltage using a signal generator. This is an essential skill for anyone working in electronic testing and calibration, and is particularly useful for testing and calibrating electronic equipment, verifying the accuracy of voltage output in a circuit, and troubleshooting and diagnosing electrical system problems.

Existing reviews of 4-20mA PWM Signal Generator

Portable PWM signal generator

After receiving the signal generator, I tested it immediately. They are compact in appearance, have a good hand feel, and a high screen display clarity. The built-in battery has a large enough capacity and can be used continuously for a whole day after a single charge. The output signal is easy to adjust and has high precision, making it very worry-free to debug process instruments. Compared with traditional bulky signal sources, this product is very convenient to carry.
