Chapter 2 Introduction
This device is economical, high-performance, multi-functional single channel waveform generators. It
uses direct digital synthesis (DDS) technology to produce accurate and stable waveforms, with a
resolution as low as 1μHz. It can generate accurate, stable, pure and low distortion output signals, also
can provide high-frequency vertical edge square waves. UTG1000’s convenient interface, superior
technical indexes and user-friendly graphical display style can help users to complete tasks quickly and
improve work efficiency.
2.1 Main Features
·Sine wave output of 20MHz/10MHz/5MHz, full frequency range resolution is 1μHz
·Square wave/pulse waveform of 5MHz, and its rising, falling, and duty cycle time are adjustable
·Using DDS implementation method, with 125M/s sampling rate and 14bits vertical resolution
·6-bit high precision frequency counter that is TTL level compatible
·Arbitrary waveform storage of 2048 points, and it can store up to 16 groups of nonvolatile
digital arbitrary waveforms
·Abundant modulation types: AM, FM, PM, ASK, FSK, PSK, PWM
·Powerful PC software
·4.3-inch high resolution TFT liquid crystal display
·Standard configuration interface: USB Device
·Supports internal/external modulation and internal/external/manual trigger
·Supports sweep output
·Easy-to-use multifunctional knob and number keyboard

4. Auxiliary Function and System Settings Button
This button includes 3 function labels: Channel settings, frequency meter, and system. A highlighted
label (the midpoint of the label is gray and font is pure white) has a corresponding sub label at the
bottom of the display.
5. Manual Trigger Button
Setting trigger, and carrying out manual trigger when flashing.
6. Modulation/Frequency Meter Input Terminal/Trigger Output Terminal
During AM, FM, PM or PWM signal modulation, when modulation source is external, modulation signal
is input through external modulation input. When frequency meter function is on, the signal to be
measured is input through this interface; when manual trigger for channel signal is enabled, manual
trigger signal is output through this interface.
7. Synchronous Output Terminal
This button controls whether open synchronous output or not.
8. CH Control/ Output
Channel output can be turned on/off quickly by pressing Channel button, also can be set by pressing
Utility button to pop-up the label, then pressing the Channel Setting softkey.
9. Direction Buttons
When setting parameters, move left and right to change number bit.
10. Multifunctional Knob and Button
Rotate the multifunctional knob to change numbers (rotate clockwise and numbers increase) or use the
multifunctional knob as direction button. Press the multifunctional knob to select function, set
parameters and confirm selection.
11. Number Keyboard
Number keyboard is used to enter parameter number 0 to 9, decimal point “.” and symbol key “+/-”.
Decimal point can change units quickly.
12. Menu Button
3 function labels will pop up by pressing the menu button: Waveform, Modulation, and Sweep. Press
the corresponding menu function softkey to get its function.
