Description: The output frequency requirements for the three waveforms are: the frequency range is adjustable between 20Hz-20kHz; the phase difference between the three waveforms is 120 degrees.
A. of sine wave signal: step 10Hz; frequency stability: better than 1/10000; nonlinear distortion coefficient is less than 3%.
B. of the square wave signal is frequency: the rise and fall time of <1 s;
The requirements of C. for triangular wave signals are that the signal frequency range is adjustable between 20Hz-20kHz.
D. for the above three frequencies are required: the frequency can be preset; when the load is 600, the output signal amplitude is greater than 3V; the output signal amplitude can be adjusted in the range of 100mv~3V, the step length is 100mV.
