DDS signal generator Compact and lightweight: This DDS signal generator is small in size and lightweight, making it convenient to carry and use. It can be powered by a power adapter or a 3.7V lithium battery (battery not included). Multifunctional: The signal source generator meter is multifunctional and can generate a variety of waveforms, including sine, square, triangle, forward sawtooth, and reverse sawtooth. It is designed for professionals. Good performance: The signal source module offers good accuracy and frequency stability and is well suited for oscilloscope sweep time factor calibration. Sine waveform 0.01 Hz–500.00 kHz (output amplitude decreases at higher frequency). Other waveforms 0.01 Hz–100.00 kHz (the upper limit of the adjustable frequency is not strictly limited, so if distortion and jitter requirements are not too , you can further increase the frequency used). Wide application: This DDS signal generator is used in conjunction with an oscilloscope for electronic circuit testing and debugging, evaluating the frequency characteristics of sound amplifiers, and impulse response testing and measurements. A filter (which can be turned on and off) accommodates sine and pulse outputs. Practical use scenarios: 1) Calibrating an oscilloscope sweep time factor and verifying waveform accuracy in electronic circuits. 2) Testing the frequency response of audio amplifiers and related components. 3) Measuring impulse response and analyzing system dynamics in research, development, or troubleshooting.
