Function Signal Generator FG-100 DDS Frequency Counter 1-500KHz Signal Waveform Small size, multiple functions, simple operation, easy to carry. With an oscilloscope, which can be used 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, which can be used in electronic circuit experiment and debugging, the frequency characteristics of audio amplifier and pulse response of test and measurement. Due to the good precision of DDS and frequency stability, is also very suitable for oscilloscope sweep time calibration factor. Square wave output also suit for oscilloscope attenuator and probe pulse adjustment, etc The main output waveform : sine wave and square-wave, Triangular wave, sawtooth wave. Maximum output amplitude : +/- 10Vpp (no-load) Output impedance : 50Ohm+/-10% Dc bias : +/- 10V (no-load) Display : LCD1602 Material:metal Resolution : 1 Hz Power supply : DC 3. 5-10V Output frequency range : Sine wave : 1Hz-500KHz Square-wave : 1 Hz - 20kHz (the valid range) Triangular wave : 1 Hz - 20KHz (the valid range) Sawtooth wave : 1 Hz - 20kHz (the valid range) Package includes: 1 x FG-100 DDS Function Signal Generator 1 x USB power adapter cable Note: Light shooting and different displays may cause the color of the item in the picture a little different from the real thing. The measurement allowed error is +/- 1-3cm.
