Features Signal generator: capable of emitting a sine wave from 1 Hz to 500 kHz, a square waveform from 1 Hz to 20 kHz, a sawtooth waveform, and a triangular waveform. Reliable to use: ensures high accuracy and also stable frequency, suitable for calibration of the scan time factor of the oscilloscope. Practical work: can be used to test and debug electronic circuits, test and measure frequency characteristics and pulse response of audio amplifiers. Square waveform: the square wave output is ideal for oscilloscope attenuator and probe pulse characteristic adjustment, etc. Simple transportation: 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 the signal. Frequency range: sine wave from 1 Hz to 500 kHz, the output amplitude is flat up to 200 kHz, 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 vibration requirements are not high and the frequency of use can be further increased. Resolution: 1Hz Output waveform: sine wave, square wave, triangular wave, forward sawtooth wave, reverse sawtooth wave, electrocardiogram, noise waves. Sinusoidal distortion: 1%, frequency < 1 KHZ; 0.5%, frequency ≥ 1KHZ. Output width: ±10V, P-P. Output impedance: 50 ohms. DC Offset: Maximum ±10V, with power off function. Save function: You can save all setting parameters. Output frequency range: Sine wave: 1Hz-500KHz, effective range. Square wave: 1Hz-20kHz, effective range. Triangular wave: 1Hz-20KHz, effective range. Saw tooth wave: 1Hz-20kHz, effective range.
