General Safety Summary
Carefully read the following safety precautions to avoid any personal injuries or
damages to the instrument and any product connected to it. To avoid potential
hazards, please use the instrument as specified.
Only qualified technical personnel should service this instrument.
Avoid fire or open flame.
Use properly rated power line connections.
Use only the specified power line which has been approved by your local
regulatory agency.
Ground the Instrument.
The instrument is grounded through the protective ground conductor of the
power line. To avoid electric shock, the ground conductor must be connected
to the earth ground. Make sure the instrument is grounded correctly before
connecting its input or output terminals.
Connect the signal wire correctly.
The potential of the signal wire ground is equal to the earth, therefore do not
connect the signal wire to a high voltage. Do not touch the exposed contacts or
components.

Introduction of T3AFG40-80-120
The manual covers the following 3 models of the T3AFG Series
Function/Arbitrary Waveform Generators: T3AFG40, T3AFG80 and T3AFG120.
The T3AFG is a series of dual-channel function/arbitrary waveform generators
with specifications of up to 120MHz maximum bandwidth, 1.2GSa/s sampling
rate and 16-bit vertical resolution. The proprietary architecture help to solve the
weaknesses inherent in traditional DDS generators when generating arbitrary,
square and pulse waveforms. Using these techniques the T3AFG provides users
with a variety of high fidelity, low jitter signals in order to meet the growing
requirements for a multitude of complex applications.
Key Features
Dual-channel, 120MHz maximum bandwidth, 20Vpp maximum output
amplitude, output with 80dB dynamic range
High-performance sampling system with 1.2GSa/s sampling rate and 16-
bit vertical resolution. No detail in your waveforms will be lost.
Innovative technology, based on a point-by-point architecture, supports
any 8pts~8Mpts Arb waveform with a sampling rate in range of
1μSa/s~75MSa/s
Innovative technology, capable of generating lower jitter Square or Pulse
waveforms, brings a wide range and extremely high precision in pulse width
and rise/fall times adjustment
A variety of analog and digital modulation types: AM DSB-AM FM PM
FSK ASK PSK and PWM
Sweep and Burst functions

Touch Screen Display
The T3AFG40-120 can only display parameters and waveform of one channel
at a time. The picture below shows the interface when CH1 chooses AM
modulation of sine waveform. The information displayed may vary depending
on the function selected.
The entire screen of the T3AFG40-120 is a touch screen. You can use your
figure or touch pen to control the instrument. Most functions and selections can
be chosen using the touch screen in a similar manner to the front panel keys
and knob.

3. Basic Waveform Parameters Area
Shows the current waveform‘s parameters of each channel. Press Parameter
and select the corresponding softkey to highlight the parameter to configure.
Then use number keys or knob to change the parameter value.
4. Channel Parameters Area
Displays the load and output settings of the currently selected channel.
Load ----Value of the output load, as selected by the user.
Press Utility → Output → Load, then use the softkeys, number keys or knob to
change the parameter value; or continue pressing the corresponding output
key for two second to switch between High Impedance and 50Ω.
High Impedance: display HiZ.
Load: display impedance value (the default is 50Ω and the range is 50Ω to
100kΩ).
Note: This setting does not actually change the instrument‘s output impedance
of 50Ω but rather is used to maintain amplitude accuracy into different load
values.
Output ----Channel output state.
After pressing corresponding channel output control port, the current channel
can be turned on/off.
5. LAN Status Icon
T3AFG40-120 will show different prompt messages based on the current
network status.
This mark indicates LAN connection is successful.
This mark indicates there is no LAN connection or LAN connection is
unsuccessful.
6. Mode Icon
T3AFG40-120 will show different prompt messages based on the current
mode.
This mark indicates current mode is Phase-locked.
