Arbitray Waveform Generator adopts large scale FPGA integrated circuit and high speed MCU microprocessor. The internal circuit adopts active crystal oscillator as benchmark. So the signal stability is greatly strengthened. With linear sweep(Max. up to 999.9s) and logarithmic frequency sweep functions.Has a frequency measurement, period measurement, positive and negative pulse width measurement and counting function. Using Dual-channel DDS signal and TTL electric level output to generate precise, stable, low distortion output signal. includes Sine wave, Square wave, Triangle wave, Saw tooth wave, Pulse wave, white noise, user-defined waveform etc. each channel can be independently set the parameters. Storage feature: You can store 99 groups instrument state parameters set by the user, can be called up to Reproduce. Frequency output of Sine wave can be up to 30MHz. 200MSa/s sampling rate. It has 60 positions for saving user-defined waveform. Waveform Length of each one is 2048 and vertical resolution is 14 bits This Signal Generator is the ideal instrument for electronic engineering, laboratories, production lines, teaching and scientific research.
