Feature: 1. Signal Generator: Able to output 1Hz-500kHz sine wave, 1Hz-20kHz square waveform, sawtooth waveform, and triangle waveform. 2. Practical Works: Can be used for testing and debugging of electronic circuits, testing and measuring the frequency characteristics and impulse response of audio amplifiers. 3. Reliable to Use: Ensuring high accuracy and stable frequency as well, suits for oscilloscope sweep time factor calibration. 4. Square Waveform: The square wave output is ideal for oscilloscope attenuator and probe pulse characteristic adjustment, etc. 5. Simple Carrying: Light in weight and compact in size, the easy carrying makes the signal sending and receiving much easier. Specification: Item Type: Signal Generator Material: ABS Function: For signal sending and receiving. Frequency Range: 1Hz-500kHz sine wave, the output amplitude is flat 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 shake 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, reverse sawtooth wave, electrocardiogram, noise waves. Sine Wave Distortion: 1%, frequency < 1KHZ; 0.5%, frequency ≥ 1KHZ. Output Amplitude: Maximum ±10V, P-P. Output Impedance: 50 ohms. DC Offset: Maximum ±10V, with shutdown function. Save 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 Manual
