DDS function signal generator from this series is a multi-functional signal generator with high precision and high performance. It adopts large scale of FPGA integrated circuits, high-speed MCU microprocessor and with high precision oscillator as base in the inner circuit, which make the signals more stable. SMT process can greatly improve the anti-interference and lifetime of the instrument. It has entirely independent dual-channel DDS signal and TTL level output, can generate signals of sine/triangle/square/sawtooth/pulse wave, white noise, etc. This instrument is of great advantage in generating signal, scanning waveform, measuring parameters, etc. It's an ideal testing or measuring instrument for electronics engineer, electronic laboratory, teaching and researching. 

Features:
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, 250MSa/s sampling rate.
With pulse trains burst output function, manual trigger, internal CH2 trigger and external trigger three trigger modes that allow the unit to any output 1~1048575 arbitrary pulse trains.
Measurement functions: 100MHz frequency meter and counter function.
Signal output amplitude range is 10mVpp- 20Vpp, DC offset adjustment range is -10V to 10V, the resolution is 0.1V.
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 10mHz.
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 20 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: extended power input range is AC85V to AC260V wide voltage.
Output short-circuit protection: all signal output can work above 60s in load short-circuit situation.
