Specification Brand : Walfront BulletPoint1 : Compact And Lightweight: This DDS functional sign 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). BulletPoint2 : Multifunctional: This sign source generator meter is multifunctional and can test a variety of forms, such as sine waves, square waves, triangle waves, forward sawtooth waves, reverse sawtooth waves, and so on. It is designed for professionals. BulletPoint3 : Good performance: This sign 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). BulletPoint4 : Wide Application: This DDS sign 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. BulletPoint5 : Excellent ABS Material: This function sign generator frequency module is made of excellent ABS material, which is sturdy and abrasion resistants, not easy to be damaged, and has a long service life.
