Features Specification Features: Compact size, complete functions, simple operation, easy to carry. It can be powered by a power adapter or a 3.7V lithium battery. Together with an oscilloscope, it can be used for electronic circuit test and debugging, frequency characteristics and impulse response test and measurement of audio amplifiers. Due to the good accuracy and frequency stability of DDS, it is also very suitable for oscilloscope sweep time factor calibration. The square wave output is suitable for oscilloscope attenuator and probe pulse characteristic adjustment. Have a filter (can be opened and closed) to suit the output of sine wave and pulse wave. This functional signal generator can test many kinds of wave forms such as: sine wave, square wave, triangle wave, forward sawtooth wave, reverse sawtooth wave, etc. It is especially designed for those professional worker. Specifications: Type: without Antenna / with Antenna (Optional) Material: ABS The main technical parameters: 1. Output waveforms: sine wave, square wave, triangle wave, forward sawtooth wave, reverse sawtooth wave, ECG wave, exponential rise, exponential fall, Lorentz pulse, Gauss pulse, Sinc pulse, half-wave, full-wave, Schumann wave, noise wave, and so on 15 kinds of waveforms. 2. Power supply: DC4-9V, DC5V is recommended when using adapter, 3.7V lithium battery is recommended when using battery power. 3. Current: 180MA at voltage 5V 4. Frequency range: sine wave 0.01Hz- 500.00kHz (with further increase in frequency, the output amplitude will decrease), other waveforms 0.01Hz-100.00kHz (but does not limit the upper limit of the adjustable frequency, if the distortion and jitter requirements are not high, the use of frequency can be further increased). 5. Resolution: 0.01Hz. 6. Sine wave distortion: <1% below 1kHz, <0.5% above 1kHz. 7. Output amplitude: Maximum ±10V (P-P). 8. output impedance: 50 ohms. 9. DC offset: maximum ±10V, with shutdown function. 10. All setup parameters can be saved. 11. there are filters can be turned on and off, can be well adapted to sinusoidal and pulse waveform output.
