Chapter 1 Introduction
1.1 Introduction
DDS-3005 USB Arbitrary Waveform Generator has one channel of arbitrary waveform output, 8 Bits output, synchronized signal outputs, two channels of Counter/Frequency Measurement inputs, 8 Bits input and external trigger input. Ur can edit the waveform arbitrarily by the mou or choo the regular waveforms such as Sine, Square, Tri-angle, Saw-tooth, TTL, White Noi, Gauss Noi, Tra
pezia, Exponent, AM and FM. The parameters, such as amplitude, frequency and offt, are also ttable. The data format of
DDS-3005 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. DDS-3005 USB adopts the DDS technology so that it has the advantages of high frequency accuracy, high waveform resolution, high reliability, and wide software support. It can be widely ud in the various kinds of electronics labs and it offers complete interface for cond time development to be jointlessly inrted into other auto-measuring systems.
1.2 Working Principle
The PC transfer the waveform data to the memorizer of the signal generator via the USB bus, the ID counter cycles and nd 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 outputted through the Cache magnifier, Low Pass Filter, and the Magnifier. The frequency counter can test the external frequency.
