1.1 Description This signal generator provides electrical signals across a range of frequencies, with square wave and pulse outputs at adjustable levels. It supports dual mode operation: PWM mode and PULSE mode. The two modes can be switched at any time, enabling quick transitions between waveform types. It serves as a signal source or excitation source for testing purposes. Key attributes Function: generates electrical signals over a variety of frequencies with square and pulse outputs at adjustable levels. Modes and control: dual mode operation with PWM mode and PULSE mode; modes can be switched at any time. Testing role: designed to serve as a signal source or excitation source for testing in lab or bench environments. Performance and usability Flexible waveform generation suitable for a range of testing scenarios. Quick mode switching to support rapid measurement and development workflows. 2 3 Practical use scenarios Electronics development and testing: simulate PWM driven devices and digital pulse signals to verify circuit response and timing. Instrument calibration and benchmarking: provide repeatable square or pulse waveforms to calibate oscilloscopes, spectrum analyzers, or trigger inputs. Laboratory experiments and education: conduct experiments requiring controlled square/pulse waveforms with convenient mode switching for different test conditions.
