Arbitrary waveform DDS 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:
Adopts DDS direct digital synthesis technology, can generate precise, stable output signals with higher distortion.
With high quality aluminium alloy shell, and powered by DC 5V, convenient and portable for use. 
Can output arbitrary waveform and conventional function waveform(sine/triangle/square/sawtooth wave signal).
All functions are digitally controlled, precise and stable.
2.4"(320*240)color display, simultaneously display dual-channel waveform parameters.
The highest output frequency(sine wave) is up to 25MHz, 200MSa/s sampling rate and 12 bits vertical resolution.
Completely independent dual-channel output, can work in sync, phase difference is adjustable.
With channel tracking function: when the tracking function is open, the all parameters of both of channel can simultaneously update according to user's configuration.
Two or more machines can realize multi-machine synchronous function with TTL_IO interface.
15 groups of arbitrary wave storage location, the memory depth/group is 2048*12bits.
High frequency resolution(total range frequency resolution is 1uHz) and high amplitude resolution(Min. is 1mV).
The duty ratio of each channel can be adjusted independently, adjustment resolution can reach 0.01%.
Can scan frequency, amplitude, bias and d uty cycle, with linear sweep and logarithmic frequency sweep modes(Max. up to 999.99s).
With pulse train trigger function, three optional trigger modes: manual trigger, inner CH2 trigger and external trigger.
Has a frequency measurement, period measurement, positive and negative pulse width measurement, duty cycle measurements and counting function.
