The Dual Channel Function Signal Generator from this series is a multi-functional signal generator(also a counter and frequency meter) with high precision and high performance. It adopts large scale of FPGA integrated circuits, high-speed MCU microprocessor and SMT in the inner circuit, which 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, step wave, 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 independent channel indicators and channel operation keys, LCD 1602 display, more convenient for the operation.
Completely independent dual-channel output, can work in sync, phase difference is adjustable.
High frequency resolution: total range frequency resolution is 10mHz.
The duty ratio of each channel can be adjusted independently.
DC offset adjustment range is -10V to 10V, the resolution is 0.1V.
Digital signal output function, CMOS output range 0~10V.
Pulse wave function: in different frequency situation, still keep the pulse width set by user, the pulse width adjustment range is 10nS~1S.
Output various of waveform: such as sine/triangle/square/sawtooth wave, pulse wave, step wave, TTL level, DC voltage.
All functions are digitally controlled, precise and stable.
Can scan frequency, with linear sweep and logarithmic frequency sweep modes(Max. up to 999s).
Storage characteristics: can store 20 groups parameters set by the user.
Frequency meter and counter functions: with 60MHz frequency meter, frequency measurement, duty cycle measurement and counting function for internal/external signals.
Input overvoltage protection: the power supply range is AC 85V to AC 240V.
Output short-circuit protection: all signal output can work above 60s in load short-cireuit situation.
