Key benefits and features Compact and multifunctional: small size with many functions, easy to operate and carry for onsite or bench use. Simple operation with helpful guidance: if the screen does not display any information, follow the video steps to obtain it. Oscilloscope compatible for testing and debugging: ideal for testing electronic circuits with an oscilloscope and for evaluating frequency response and audio impulse response. Square waveform utility: the square waveform is suitable for use as an oscilloscope attenuator and for adjusting probe impulse response. Filtering support: includes a filter to suit the outputs of sine wave and pulse wave signals. 23 practical use scenarios Scenario 1: Debug and validate electronic circuits on a benchtop oscilloscope. Use the device to test circuit behavior and analyze frequency response and audio impulse response. Scenario 2: Calibrate oscilloscope probes and adjust impulse response. Utilize the square waveform output to set up appropriate probe and attenuator characteristics. Scenario 3: Signal verification for sine and pulse wave outputs. Apply the builtin filter to ensure clean, accurate sine and pulse wave signals during testing.
