DDS Signal Generator 1Hz-20kHz Square Sawtooth Triangle Signal Generator For Sending Feature:1. Signal generator: capable of output 1Hz-500kHz sine wave, 1Hz-20kHz square wave, sawtooth shape and triangle shape.2. Practical works: can be used for testing and debugging electronic circuits, testing and measuring frequency response and impulse response audio amplifiers.3. Reliable to Use: Ensure high accuracy and stable frequency, match the oscilloscope timing factor calibration.4. Square waveform: the square wave output is ideal for attenuating the oscilloscope and adjusting the pulse characteristics of the probe, etc.5. Simple Carrying: Lightweight and compact size, easy carrying makes sending and receiving signal much easier. Specification:Item Type: Signal Generator Material: ABS Function: for sending and receiving signal. Frequency range: 1Hz-500kHz sine wave, the output amplitude is flat up to 200kHz, and the output amplitude will decrease as the frequency increases. And 1Hz-20kHz other waveforms, but the upper limit of the adjustable frequency is not limited if the distortion and shaking requirements are not high, and the frequency of use can be further increased. Resolution: 1Hz. Output waveform: sine wave, square wave, triangle wave, forward sawtooth wave, sawtooth backward, electrocardiogram, noise waves. Sine wave distortion: 1%, lt frequency; 1KHZ; 0.5%, GE frequency; 1KHZ. Output amplitude: maximum ± 10V, P-P. Output impedance: 50 ohms. DC offset: maximum ± 10V, with shutdown function. Saving function: all setting parameters can be saved. Output Frequency Range:Sine Wave: 1Hz-500KHz, Effective Range. Square Wave: 1Hz-20kHz, effective range. Triangle Wave: 1Hz-20KHz, effective range. Sawtooth Wave: 1Hz-20kHz, effective range. Package List:1 x Signal Generator1 x USB Cable1 x User ManualHow to Use:1. Mode: Waveform switch button.2.
