Compact and lightweight - The DDS signal generator is small and lightweight for easy portability and convenient use. - It can be powered by a power adapter or a 3.7V lithium battery (battery not included). Multifunctional - Measures and generates multiple waveform forms including sine, square, triangle, forward sawtooth, and reverse sawtooth. - Designed for professional use with versatile testing capabilities. Good performance - Offers good accuracy and frequency stability, suitable for oscilloscope sweep time factor calibration. - Sine waveform: 0.01 Hz to 500.00 kHz (output amplitude decreases at higher frequencies). - Other waveforms: 0.01 Hz to 100.00 kHz (the upper limit of adjustable frequency is not strictly limited; if distortion and jitter requirements are not too high, the frequency can be increased further). Wide application - Used with an oscilloscope for electronic circuit testing and debugging, and for examining the frequency characteristics of sound amplifiers and impulse responses. - Includes a filter (on/off) to accommodate sine and pulse outputs.
