Fg-100 dds sine wave machine function signal generator accessories meter practical tool high precision source portable stable Application: Due to the high precision and stable frequency of the DDS, it is also very suitable for the scan time calibration factor of the oscilloscope. Multi Purpose: The rectangular wave output is also suitable for oscilloscope attenuation links and probe pulse adjustment. Output Waveform: The main output waveform are sine wave and square shaft, triangular shaft, sawtooth shaft. With Filter: Have a filter (can be turned on and off) that matches the output of the sine wave and pulse wave. Portable: Small size, multiple functions, easy operation, easy to carry. Power Supply: DC4-10V. It is recommended to choose DC5V when using the adapter, and 3.7V battery when using battery power. Current: 250MA when the voltage is 5V. Frequency Range: Sine wave 1Hz-500kHz (the output amplitude will decrease with the further increase of frequency), other waveforms 1Hz-50kHz (but the upper limit of adjustable frequency is not limited, if the distortion and shaking requirements are not high, use the frequency Can be further increased). Tips: All setting parameters can be saved. There are filters that can be turned on and off, which can be well adapted to sine and pulse waveform output.
