Using DDS direct digital synthesis technology to generate precise, stable, low distortion output signal. CH1 and CH2 completely symmetrical two channels, each channel can be independently set the parameters. Supports user-defined waveform, each arbitrary waveform memory depth 2048*12bits, 200MSa/s sampling rate. With pulse trains burst output function,allow the unit to any output 1~1048575 arbitrary pulse trains. Measurement functions: 60MHz frequency meter and counter function. Signal output amplitude range is 5mVpp- 20Vpp, DC offset adjustment range is -120% to +120%, the resolution is 1%. Digital signal output function, CMOS output range 0~10V. Waveform generator up to 12 bits wide, the output waveform is more delicate, waveform distortion is low. With full CNC functions, display and adjust of current output signal parameters, such as the amplitude, offset, frequency, duty cycle, and the phase difference of two signals. After connected with computer, user can control signal generator functions and parameters, and can edit and download arbitrary waveform. High frequency accuracy and resolution: frequency accuracy up to 10^(-6) magnitude, total range frequency resolution is 0.01Hz. Tracking function: built-in frequency, amplitude, offset, duty cycle, waveform and other parameters follow function, easy to use. Scanning features: frequency linear sweep and logarithmic sweep function, start and end points of scanning can be set freely. Storage features: can store 16 groups parameters set by the user. Operation: key operation, LCD1602 display in English, directly digital setting parameters or continuous adjustment knob. Input over-voltage protection:DC5V power supply, insert more than 5V voltage will not damage the machine. Output short-circuit protection: all signal output can work above 60s in
