Baseband Signal
1. Baseband Output
Press I/Q  BaseBand  Switch to select “On” or “Off”.
 On: enable the baseband output function. The RF signal generator outputs
the I (In-Phase) and Q (Quadrature Phase) components of the I/Q
modulation from the [I OUT] and [Q OUT] connectors on the rear panel.
 Off: disable the baseband output function.
2. Baseband Level
Press I/Q  BaseBand  Level to set the amplitude of the baseband output
signal.
 Use the numeric keyboard to input the amplitude value and select the
desired unit from the pop-up unit menu or unit keys. You can also press
Enter to select the default unit (dBm).
 The amplitude units available are V, mV, μV, nV and dBm.
 You can press the left/right direction keys to enter the parameter editing
state. Then, move the cursor to the specified digit and use the up/down
direction keys or knob to modify the parameter value.
 You can also use the up/down direction keys or knob to modify the
amplitude at the current step.
 Press Step to set the step.
3. ARB
Press I/Q  BaseBand  ARB to enter the store and recall interface. At this
time, the message “You can load the ARB files” is displayed in the user interface.
Press Enter or the right direction key to unfold the current directory and select
the ARB file (namely wavetable file; the format is *.arb) to be loaded. Then
press Recall to load this file. The message “File loading succeeded” is displayed
after the file is loaded. For more information about how to load a file, please
refer to “Store and Recall”.
Tips
The loadable ARB files include the default wavetables of the instrument and
the wavetables which are downloaded to the DSG3000 using the Ultra IQ
Station PC software. For more information about how to download the ARB
file, please refer to Ultra IQ Station_Help Document .
