DDS Function Generator Digital Display Waveform Signal Source Frequency Counter Tester FG‑100 Item Type: DDS Function Generator Material: ABS Frequency Range: Sine wave 1Hz-500kHz (where the output amplitude is flat to 200 kHz, and the output amplitude will decrease as the frequency increases), other waveforms 1Hz-20kHz (The upper limit of the adjustable frequency is not limited. If the requirements for distortion and shaking are not high, the frequency of use can be further increased). Resolution: 1Hz Output Waveform: Sine wave, square wave, triangle wave, forward sawtooth wave, reverse sawtooth wave. Sine Wave Distortion: <1% below 1kHz, <0.5% at 1kHz and above. Output Amplitude: Maximum ±10V (P-P) Output Impedance: 50Ω DC Offset: Maximum ±10V, with shutdown function. Power Supply: DC3.5-10V. It is recommended to choose DC5V when using the adapter, and 3.7V lithium battery when the battery is used for power supply.
