To open the instrument node, click 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. If this is an inter-band setup, the node indicates whether the instrument is playing the role of a master or slave in the configuration. (For more information on inter-band configurations, see Inter-band Carrier Aggregation Setup.)
The figure below shows the Instrument node for a signal generator connection. For the PXB, only the Configuration, Basic and Dual ARB selections are available in the Instrument Controls list. Click a button or click an item in the Instrument Controls list for information on that button or item.
Click the button to send the parameters to the connected instrument.
Downloading

also updates settings to the instrument.
Click the button to retrieve the parameters from the connected instrument.
Click the button to deactivate remote operation and activate signal generator local (front panel) control.
Click 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.
Click 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.

Click the button to execute a manual power search calibration. This is an internal calibration routine that improves output power accuracy when the ALC is turned off. A power search is recommended for pulse-modulated signals with pulse-widths less than two microseconds.
