Features Signal Generator: Can output 1Hz-500kHz sine wave, 1Hz-20kHz square wave, sawtooth wave, triangle wave. It can be used with the oscilloscope to test and debug the frequency response and impulse response of electronic circuits, audio amplifiers, and to calibrate the sweep time factor of the oscilloscope. Practical Work: It can be used for testing and debugging of electronic circuits, testing and measuring the frequency characteristics and impulse response of audio amplifiers. The purpose of using a signal generator to test an electronic tachometer can be achieved at the lowest cost. Reliable Use: This function signal generator can test a variety of waveforms to ensure high precision and stable frequency, and is suitable for oscilloscope scan time factor calibration. Square Wave: The square wave output is ideal for oscilloscope attenuators and probe pulse characteristics adjustment, etc. Square waves are suitable for adjustment of oscilloscope attenuators and probe impulse responses. Easy to Carry:Light weight, small size, easy to carry, make it easier to send and receive signals. Useful for troubleshooting electronic circuits, characterizing the frequency response of audio amplifiers, or measuring impulse responses. 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.
