The three-channel Function / Arbitrary waveform generator is a set of Function Signal Generator, Pulse Generator, Analog / Digital modulator, Sweep, Counters and Frequency Meter and other functions in a high Performance. Adopt the Direct Digital Synthesizer (DDS) technology and provide stable, precise, pure and low distortion signals. 2.4 inch TFT Color LCD with 320×240 resolution, displaying parameters and graphics of the three channels at the same time. Independent three-channel output (equivalent to three independent signal sources) can work synchronously and the phase difference can be adjusted accurately. With channel tracking function, all parameters of the three channels can be updated according to user's configuration at the same time when the tracking is opened. Can output up to 100 groups of functions / arbitrary waveform, contains 33 groups of preset waveforms and 64 groups of user-defined waveforms. Sweep Function: It can sweep 4 properties of signals including frequency, amplitude, offset and duty cycle; It has Linear and Logarithm two sweep types; 0.01S~999.99S sweep time; Up, Down and roundtrip sweep directions.
