Compact and lightweight: This DDS functional generator is small and easy to carry. It can be powered by a power adapter or a 3.7V lithium battery (battery not included). Wide application: Use it with an oscilloscope for electronic circuit testing and debugging, for analyzing the frequency characteristics of sound amplifiers, and for impulse response testing and measurements. A filter that can be turned on and off accommodates sine and pulse outputs. Multifunctional: This source generator meter supports multiple waveforms, including sine, square, forward sawtooth, and reverse sawtooth, among others. Good performance: The device offers solid accuracy and frequency stability and is well suited for oscilloscope sweep time factor calibration. Sine waveform: 0.01 Hz to 500.00 kHz (output amplitude decreases as frequency increases). Other waveforms: 0.01 Hz to 100.00 kHz (the upper limit of adjustable frequency is not strictly limited, so if distortion and jitter requirements are not too , you can push the frequency higher). Use scenarios: Laboratory calibration: Generate precise test signals for oscilloscope sweep time calibration and circuit debugging. Audio equipment testing: Assess frequency response and impulse behavior of amplifiers using sine and pulse outputs. Electronics prototyping: Use various waveforms to stress test microcontroller timing, PWM signals, and other timingsensitive circuits.
