GAO 3005 USB Arbitrary Waveform Generator and Frequency Counter - Introduction:

The GAO3005 USB Arbitrary Waveform Generator has one channel of arbitrary waveform output, 8 bit output, synchronized signal outputs, two input channels for counter/frequency measurement, 8 bit input and external trigger input. Users can arbitrarily edit the waveform using a mouse, or they can choose from regular waveforms such as Sine, Square, Triangle, Saw-tooth, TTL, White Noise, Gauss Noise, Trapezoid, Exponent, AM and FM. Parameters, such as amplitude, frequency and offset, are also user settable. The data format of GAO3005 USB is completely compatible with that of Tektronix; it can directly read the waveform data files produced by the Tektronix oscilloscope or Tektronix waveform editor software and redisplay the waveform. GAO3005 USB adopts DDS technology so that it has the advantages of high frequency accuracy, high waveform resolution, high reliability, and wide software support. This product ships with both SDK and API and can be easily integrated or embedded into other auto-measuring systems

GAO 3005 USB Arbitrary Waveform Generator and Frequency Counter - Working Principle:

The PC transfers the waveform data into the memory of the signal generator via the USB bus, the ID counter cycles and sends the period waveform data to the DAC circuits, the DDS (Direct Digital Synthesized) circuit produces the corresponding DAC refreshing clock. The waveform of DAC is output through the Cache magnifier, Low Pass Filter, and the Magnifier. The frequency counter can test the external frequency.
