Have a filter (can be turn on/off ) to suit the output of sine and pulse wave..
Due to the high precision and stable frequency of the DDS, it is also very suitable for the oscilloscope's scan time calibration factor..
The main output waveform are sine and square‑wave, triangular wave, sawtooth wave..
Small size, multiple functions, simple operation, easy to carry..
The square output is also suitable for oscilloscope attenuators and probe pulse adjustment..
