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. User can edit the waveform arbitrarily by the mouse or choose the regular waveforms such as Sine, Square, Tri-angle, Saw-tooth, TTL, White Noise, Gauss Noise, Trapezia, Exponent, AM and FM. The parameters, such as amplitude, frequency and offset, are also settable.

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 used in the various kinds of electronics labs and it offers complete interface for second time development to be jointlessly inserted 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 send 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 1

Magnifier. The frequency counter can test the external frequency. 1.3 Hardware Specification 2 Waveform Output Channel Frequency Range 0.1Hz(DC)~5MHz Resolution 0.01Hz DAC Clock DAC Clock 0~50MHz Continuously adjustable, in step of 0.2Hz Channels 1CH waveform output Memory Depth 256KSa Vertical Resolution 14 Bits Stability Amplitude ±10V Max.
