Small size, a number of functions, simple operation, mushy to carry. With an oscilloscope, which are utilized in electronic circuit experiment and debugging, the frequenc Due to the good precision of DDS and frequency stability, is also very suitable for oscilloscope swe COLOR:white Material:metal With an oscilloscope, that are used in electronic circuit experiment and debugging, the frequency characteristics of audio amplifier and pulse reaction of confirm and measurement. Due to the good precision of DDS and frequency stability, also is very compatible for oscilloscope sweep time calibration factor. Square wave output also move well with for oscilloscope attenuator and probe pulse adjustment, and so forth The leading output waveform : sine wave and square-wave, Triangular wave, wave. Maximum output amplitude : +/- 10Vpp (no-load) Output impedance : 50Ohm+/-10% Dc bias : +/- 10V (no-load) Display : LCD1602 Material:metal Resolution : 1 Hz Power transport : DC 3. 5-10V Output frequency differ : Sine wave : 1Hz-500KHz Square-wave : 1 Hz - 20kHz (the valid range) Triangular wave : 1 Hz - 20KHz (the legitimate range) wave : 1 Hz - 20kHz (the legitimate range) Package includes : 1 x FG-100 DDS Function Signal Generator 1 x USB strength adapter cable 1 x English handbook Note: Light and sundry exhibits could cause the color of the thing within the photo slightly various from the real thing. The length allowed error is +/- 1-3cm.
