Instrument (Signal Generators)

This topic describes the software's instrument-control properties for the following signal generator models:

To open the property grid, click Instrument in the software's tree view. If you are connecting to multiple instruments, the tree view displays a node for each.

The figure below shows the available property categories for a signal generator connection. Click the image links for detailed descriptions.

Capability set to Waveform Playback and Phase Compensation set to Auto, Manual, or Off

Capability set to Real-time Uplink or Phase Compensation set to Auto (Real-time) or Manual (Real-time)

State On

Turns the application on, generating the real-time IQ signal in the connected instrument with the parameters you set in the software.

[:SOURce]:RADio:NR5G[:BBG][:STATe] ON|OFF|1|0

[:SOURce]:RADio:NR5G[:BBG][:STATe]?

State Off

Turns the application off, disabling the real-time IQ and RF signals on the connected instrument.

[:SOURce]:RADio:NR5G[:BBG][:STATe] ON|OFF|1|0

[:SOURce]:RADio:NR5G[:BBG][:STATe]?

Update to Instrument

Click this button to send the parameters to the connected instrument.

Update from Instrument

Click this button to retrieve the parameters from the connected instrument.

Preset

Click this 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.

DC Cal

Click the DC Cal button 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 signal generator's settings change.

Download a waveform to set the correct parameters for the target instrument and activate this button.

You can set this calibration to occur automatically. See Perform DC I/Q Calibration.

*OPC

Power Search

Set ALC to Off to activate this button.

Click the Power Search 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.

Download a waveform to set the correct parameters for the target instrument.
