FeelTech FY3200S Series Fully Numerical Control Dual Channel Function-Arbitrary Waveform Generator User Manual

FeelTech FY3200S Series Fully Numerical Control Dual Channel Function-

Arbitrary Waveform Generator

Introduction of the instrument

This manual applies to each mode of FY3200S series DDS Function Signal Generator. In the series, the last two digits “xx” represent the upper limit frequency value (MHz) of Sine Wave for each mode. For example, FY3225S，“25” means the upper limit frequency of Sine Wave is 25MHz. The instrument adopts large scale CMOS integrated circuit and high speed microprocessor. The internal circuit adopts active crystal oscillator as benchmark. So the signal stability is greatly strengthened. Surface mounting technology improves interference immunity and operational life span. It has Dual-channel DDS signal output, includes Sine wave, Square wave, Triangle wave, Sawtooth wave and user-defined waveform. The amplitude, offset and phase can be controlled. Meanwhile, it has TTL electric level output, External frequency measurement, counter and sweep functions including Linear sweep and Logarithmic sweep. Both the sweep frequency and time can be set arbitrarily. It’s the ideal instrument for electronic engineering, laboratories, production lines, teaching and scientific research.
