The User Interface at a Glance
The SDG6000X displays parameter and waveform information of one channel
at a time. The picture below shows the interface when CH1 is selected. In this
example, the waveform is an AM modulated sine wave. The information
displayed may vary depending on the function selected.
The entire screen of the SDG6000X is a touch screen. You can use your finger
or a 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.
1. Waveform Display Area
Displays the currently selected waveform of each channel. Click on the screen
here, then the "Waveforms" button will be highlighted.
2. Channel Status Bar
Indicates the selected status and output configuration of the channels. Click on
the screen here to switch to the corresponding channel. Click here again,
shortcut menu of front panel's function keys will be shown: Mod, Sweep, Burst,
Parameter, Utility and Store/Recall.

3. Basic Waveform Parameters Area
Shows the current waveform parameters of each channel. Click the
parameters to be set, and the parameters will be selected and highlighted.
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.
Select the corresponding parameter to highlight it, and then use the softkeys,
number keys or knob to change the parameter value; or press the
corresponding output key for two seconds to switch between High Impedance
and 50Ω.
High Impedance: Displays HiZ, and assumes a load impedance of 1 MΩ.
Load: Displays the set impedance value. The default is 50 Ω and the range is
from 50 Ω to 100 kΩ.
Note: This setting does not actually change the instrument’s output impedance
of 50 Ω but rather is used to maintain amplitude accuracy when fed into
different load values.
Output ----Channel output state.
Click on the screen here or pressing corresponding channel output control
button, the current channel can be turned on/off.
5. LAN Status Icon
SDG6000X 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.
