Thank you for purchasing DDS Function/Arbitrary Wave⁃
form Generator.
DDS function generator is the updated product of tradition⁃
al analog function generator with more function advantages
and better cost performance. It is now widely used in manu⁃
facturing, teaching and researching.
This series have the following features：

● DDS technique is applied with the same high frequency
stability and resolution as crystal oscillator and extreme low
frequency is realizable.

● VLSI and SMT are used. Auto-calibrating program with⁃
out mechanical potentiometer can insure the high reliability.

● Double channels output, frequency of both A/B channels
reach max limit of the instrument. (max output of channel B
of UTG9040BS/DS is 20MHz)

● Ten basic waveforms includes Sine, Square, Triangle,
Pulse, Up Ramp, Down Ramp, P- Exp, N- Exp, Sine (x) /x
and Noise wave.

lish menu.

● Favorable human-machine interface with convenient op⁃
eration. Each one button to each waveform and modulation
waveform. The parameters can be keyed in by number but⁃
tons or by combined operation of buttons and pulse knob.

●All settings and conditions for waveforms are saved auto⁃
matically and can be recovered automatically.

● Convenient and practical software for arbitrary waveform
programming can download and save 16 arbitrary wave⁃
forms, edit and output 4 arbitrary waveforms at the same
time. The arbitrary waveforms could be output independent⁃
ly or in groups. (optional)

●USB interface (applied for DS series)

● The protection from the instrument may be ruined if it is

not used as guided by the manual

● The power plug should be grounding protected.

● The instrument should be used in the specified condi⁃

tions as followed (temperature 0℃～40℃, humidity≤80%) ,
The best operation condition is at the indoor temperature
(around 25℃)

● As for the instrument with its sine wave frequency is ≤
20M, the signals of more than 20 Vpp(open- circuited) or
10Vpp (50Ω) cannot be connected to the signal output. If
the frequency is ＞20M the signals of more than 6 Vpp
(open-circuited) or 3Vpp (50Ω) cannot be connected to the
signal output.

● Replace the new fuse only after the power is switched
off and the specified fuse of rated current (220V/0.5A)
should be used.

● The protection of the product may be ruined when it can
not work properly. Please contact our sales department or
service station to get quick and effective after-sale service

if there is anything wrong with our product.

● The cover of the case cannot be opened except by pro⁃
fessional technicians.

are determined by the wave created by the arbitrary wave

software on PC.

4.17 Arbitrary wave download and save (applied for DS se-

ries)

Install the drive on PC and open the arbitrary wave soft-

ware. Connect the product with PC through USB to down-

load and save arbitrary waves.

First create or load waveform in the software, name it(or

skip), choose proper parameters such as port numbers.

See 5. Software for Arbitrary Waveform Programming.

In Config setting interface as Fig. 29 press F3-ArbLd to ac-

cess the start interface of arbitrary wave downloading and

saving as Fig. 32

Use the roller to choose the page 01~16 to save and press

download button on PC afterwards. On the interface there
will be display of“loading...”and after downloading is com-
pleted display of“OK” together with the waveform name

(blank if no name). Then choose another page to continue

downloading another wave and 16 different waves can be

saved in this product.The page can be reedited with the

newest wave saved. F6- Return for returning to the Config

setting interface as Fig. 29.

5. Software for Arbitrary Waveform Programming（applied

23

UTG9000BS/DS

for DS series)
It’s a green software on PC that no need to be installed. It’

s run in Windows and with the mouse you can conveniently

draw, revise, save or download any arbitrary waveform.

5.1 Software interface

The software interface is as Fig. 33. On top is the pull­down menu. Also there’s another operation way of icon

buttons under the menu line which is visual and simple.

Press one with the left mouse button to access correspond-

ing mode of operation. When the arrow is on one button

there will be description of the function under.

5.2 Arbitrary waveform programming

Left mouse button draw curve

Right mouse button draw straight line

Click by left mouse button place the remark
It’s very convenient to draw arbitrary waveform with the

functions above by the mouse. For those waveforms which
require the sine law or symmetry there’re basic wave of

sine or square wave in system to be modified on.

★ The frequency and amplitude of arbitrary wave output

are relevant to the wave parameters created by the arbi-

trary wave software on PC.

5.3 Data format and editing

Data support by the software has two formats of own for-

mat and text format. Arbitrary waveform drawn can be

saved and read in.

The own format is used to save waveform data created by

24

UTG9000BS/DS

arbitrary waveform programming software.

The text format is used for the arbitrary waveform program-

ming software to read in waveform files created by user in

other methods with the file as .txt.
Txt file can be opened and edited in“notepad”interface

only if keyed in in hexadecimal. Every 8 numbers are re-

garded as one dot of the wave. There should be space be-

tween dots and the size of the number is related to the

height of the wave dot. If less than 8 numbers it is regard-

ed as default height. The highest corresponds to 1big, the

second highest corresponds to 1/16 big and ... The data
range is 0～7FFFFFFF and the corresponding waveform
value is 1 at max and -1 at min.- 1～1 stands for the peak

value range of signal change.

Text file which is edited can be opened in arbitrary wave

software interface to be modified, reviewed, downloaded

and saved.

5.4 arbitrary waveform download

1. Before downloading the drive should be installed on PC

side and the serial port number to which of PC the genera-

tor is connected should be confirmed so it can be chosen

in the pull- down menu of the software when waveform

downloading or there may be error.

2. choose resolution ratio. The software has 4 resolution ra-

tios of 1,2,4 and 8. Smaller number means higher resolu-

tion for editing waveform with lower frequency while larger

number means lower resolution for editing waveform with

higher frequency.

3. Download. Click the menu of download and click start.
There’s display of“loading...”in the interface and“OK”

when downloading is finished.
