Feature: 1. Compact And Lightweight: This DDS functional signal generator is small in size and lightweight, which makes it very convenient to carry and use, and it can be powered by a power adapter or a 3.7V lithium battery(battery not included). 2. Multifunctional: This signal source generator meter is multifunctional and can test a variety of forms, such as sine wave, square wave, triangle wave, forward sawtooth wave, reverse sawtooth wave, and so on. It is designed for professionals. 3. Good performance: This signal source module has good accuracy and frequency stability, it is also well suited for oscilloscope sweep time factor calibration. Sine waveform 0.01Hz‑500.00kHz (output amplitude decreases with further increase in frequency), other waveforms 0.01Hz‑100.00kHz (but does not limit the upper limit of the adjustable frequency, so if distortion and jitter requirements are not too high, you can further increase the frequency used). 4. Wide Application: This DDS signal generator is used in conjunction with an oscilloscope for electronic circuit testing and debugging, frequency characteristics of sound amplifiers and impulse response testing and measurements. There is a filter (which can be turned on and off) to accommodate sine and pulse outputs. 5. Excellent ABS Material: This function signal generator frequency module is made of excellent ABS material, which is sturdy and abrasion resistant, not easy to be damaged, and has a long service life. Specification: Item Type: Function Signal Generator Material: ABS Size: Approx. 140 x 80 x 26mm / 5.51 x 3.15 x 1.02in Main Technical Parameters: Output Waveforms: Sine Wave, Square Wave, Triangle Wave, Positive Sawtooth Wave, Negative Sawtooth Wave, Electrocardiogram Wave, Exponential Rise, Exponential Fall, Lorenz Pulse, Gaussian Pulse, Sinc Pulse, Half Wave, Full Wave, Noise Wave Power Supply: DC4-9V (Recommend Using DC5V Adapter when using adapter, or 3.7V Lithium Battery when using battery power(battery not included) ) Current: 180MA at 5V Frequency Range: Sine Wave 0.01Hz-500.00kHz, Other Waveforms 0.01Hz-100.00kHz Resolution: 0.01Hz Sine Wave Distortion: <1% Below 1kHz, <0.5% Above 1kHz Output Amplitude: Maximum ±10V (P-P) Output Impedance: 50 ohm DC Offset: Maximum ±10V Can save all set parameters. Comes with a filter that can be turned on and off to adapt to sine and pulse waveform output. Features: Compact size, fully functional, easy to operate and portable. It can be powered by power adapter or 3.7V lithium battery. Used in conjunction with an oscilloscope, it can be used for electronic circuit testing and debugging, frequency characteristics of sound amplifiers and impulse response testing and measurement. Because of its good accuracy and frequency stability, the DDS is also well suited for oscilloscope sweep time factor calibration. The square wave output is suitable for oscilloscope attenuator and probe pulse characterization. There is a filter (which can be turned on and off) to accommodate sine and pulse wave outputs. This function signal generator can test a variety of waveforms, such as: sine wave, square wave, triangle wave, forward sawtooth wave, reverse sawtooth wave and so on. It is specially designed for professional workers.. Package List: 1 x Function Signal Generator 1 x USB Power Cable 1 x BNC Coaxial Cable 1 x Dual End BNC Cable 1 x Antenna
