To open the Instrument node, click Instrument in the tree view. If there is more than one instrument connection, there will be a corresponding number of Instrument listings in the tree view.
The figure below shows the instrument controls for the connected signal generator. For the PXB, only the , and selections are available in the Instrument Controls list. For the EXT, all of the instrument controls are available, except for the: , , and selections. Click a button or an item in the Instrument Controls list for information on that button or item.
Press the button to send the parameters to the connected instrument.
Downloading
a waveform or pressing the Update Hardware Settings button 
also updates settings to the instrument.
Press the button to retrieve the parameters from the connected instrument.
Press the button to deactivate remote operation and activate signal generator local (front panel) control.
Press the button to set the signal generator to a factory-defined or user-defined state.
Refer to the signal generator's user's guide for information on setting a user-defined state.
Press the button to execute an I/Q DC calibration to minimize errors associated with offset voltages.
minimizes I/Q offset errors for a single frequency only and must be repeated if the signal generator's settings change.
