?Strongly steady electro-circuit.6-phases from 0.2Hz-2MHz.
?Digital display about frequency &operate conveniently.
?Output for empty carry arrive at 5V,600? carried will be higher than 2V(sine wave).
?Output voltage balance may be adjusted by 2 groups of attenuator every 20dB and 40dB, total 60dB or potentiometer in continuity.
?Sine wave of square wave may be chosen to output.
