User Interface
The T3AFG30-60 can only display parameters and waveform information for
one channel at a time. The picture below shows the interface when CH1
chooses AM modulation of a sine waveform. The information displayed may
vary depending on the function selected.
Figure 1-4 User Interface
1. Waveform Display Area
Displays the currently selected waveform of each channel.
2. Channel Status Bar
Indicates the selected status and output conguration of the channels.
3. Basic Waveform Parameters Area
Shows the current waveform parameters of each channel. Press Parameter
and select the corresponding softkey to highlight the parameter to congure it.
Then use the 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 seconds 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 dierent load
values.
Output ---- Channel output state.
After pressing corresponding channel output control port, the current channel
can be turned on/o.
5. LAN Status Icon
The T3AFG30-60 will show dierent prompt messages based on the current
network status.

1.4 To Set Modulation/Sweep/Burst
The three keys on the front panel, as shown in Figure 1-13, are used for the
modulation, sweep and burst settings. This section will help explain how to use
these functions.
Figure 1-13 Modulate/Sweep/Burst Key
1. Press Mod, the Modulation function will be enabled.
The modulated waveform can be changed by modifying the parameters such as
Type, Source, AM Depth, AM Freq, Shape, etc. The T3AFG30-60 can modulate
waveforms using AM, FM, PM, ASK, FSK, PSK, PWM and DSB-AM,
etc. Pulse waveforms can only be modulated using PWM. Noise and DC
waveforms cannot be modulated.
Figure 1-14 Modulation Display Interface
2. Press Sweep, the Sweep function will be enabled.
Sine, square, ramp and arbitrary waveforms support the sweep function. In
sweep mode, the T3AFG30-60 can generate signals with variable frequency.
The available range of sweep time is from 1ms to 500s. The trigger source can
be Internal, External or Manual.
