Features:  This manual applies to each model of FY8300S series Function/Arbitrary Waveform Signal Generator. The last three characters of the model indicate the up limit output of Sine Wave (MHz). For example, the "60M" of the Model Number "FY8300-60M" indicates the Sine wave maximum output frequency is up to 60MHz.  This series Three-channel Function / Arbitrary waveform generator is a set of Function Signal Generator, Arbitrary Waveform Generator, Pulse Generator, Analog / Digital modulator, Sweep, Counters and Frequency Meter and other functions in a high Performance, cost-effective, multi-function signal generator. Abundant shortcut keys and graphical user interface simplifies every operation. Users do not have to spend a lot of time to learn and familiar with the operation of the instrument, you can be skilled use. For education, research and development, production, testing, maintenance and other industries to provide a new choice.  The instrument adopt the Direct Digital Synthesizer (DDS) technology and provide stable, precise, pure and low distortion signals. Surface mounting technology improves interference immunity and operational life span. Can output up to 97 groups of functions / arbitrary waveform, contains 33 groups of preset waveforms and 64 groups of user-defined waveforms.
