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

2
Magnifier. The frequency counter can test the external frequency.

Chapter 3 Software Operations
3.1 Installing the Hardware
Connect the USB instrument to the USB port through the USB cable, the PC
prompts that new USB device is found.
The PC will automatically find the new USB device and choose the
nominated directory to install the driver.
Choose the correct directory of the driver through the browser or search

9
in the CD driver.
Click "Continue"to finish the installation.

10

11
The system will notify that the new USB device can work normally now.
After the successfully installation, in the Device Manager, you can see the
DDS-3005 USB device.

12
3.2 Installing the Software
The setup software of DDS-3005 USB is in the CD, run the Setup.exe to
install the software.

13
3.3 Run the DDS-3005 USB
Click "Start"- "Program"-"DDS-3005 USB"-"DDS-3005 USB"to go into
the main window, shown as below:

14
3.4 Choose the Wave Forms
Press down any button of certain waveform to switch to the output of
such kind of waveform. When switch to arbitrary waveform from other kind of
waveform, the edition work can be done on the original wave form.
3.5 Waveform Parameter Setup
Select the "Parameters"in the Menu, there are the choices for setting of
various waveform parameters.

15
Example "modulation Signal":
Set the parameters in the dialog box.
3.6 Counter/ Frequency Measurement
To measure by the buttons shown as below:

16
Including "High Frequency/ Low Frequency”, "Coupling Mode"
"Frequency Measure/ Counter"and the function’s "On/Off".
3.7 Waveform Output Control
By the following buttons to control the output dot numbers, trigger mode,

17
3.8 Edition of Arbitrary Waveform
Choose the "Arbitrary Dot Edit"in the "Edit"Menu, or double-click the
display window to edit each dot, or use the mouse the draw the
waveform.
3.9 Waveform Data Files
The data format of DDS-3005 USB is ".CSV". Its format is compatible
with the CSV file produced by the Tektronix ARBExpress software. User
can edit or set up the required CSV waveform and also use Excel to open
and edit the CSV wave files.
Warning: Any usage beyond the limit of the input & output signal ports
as well as strong electrical field and static may cause the abnormal
working or even damage to the instrument.
