Instrument

Clicking Instrument in the Closedtree view displays the Instrument Settings table in the node view of the main window.

The figure below shows the Instrument node for a signal generator connection. Click a button or click an item in the Instrument Control list for information on that button or item.

Click the plus box to expand the table and access those parameters.

Update to Instrument

Press this buttonClosed to send the software parameters to the connected instrument.

Update from Instrument

Press this buttonClosed to retrieve the parameters from the connected instrument.

Local

Press this buttonClosed to deactivate remote operation and return the instrument to local (front panel) control.

Preset

Press this buttonClosed to set the instrument to a known state, either factory-defined or user-defined.  

Refer to the instrument's user's guide for information on setting a user-defined state.

DC Cal

Press this buttonClosed to execute an I/Q DC Calibration to minimize errors associated with offset voltages.

DC Cal minimizes I/Q offset errors for a single frequency only, and must be repeated if the instrument's settings change.

Download a waveform to set the correct parameters for the target instrument, and make this button available.

Power Search

Press this buttonClosed to execute a manual power search calibration.

This is an internal calibration routine that improves output power accuracy when ALC is off. A power search is recommended for pulse-modulated signals with pulse-widths less than two microseconds.

Download a waveform to set the correct parameters for the target instrument, and set ALC to Off to make this button available.
