Remarks


For a vector signal analyzer (VSA), the system is defined as the RF downconverter for all interfaces between the RF IN connector on the RF downconverter front panel and the IF IN connector on the digitizer front panel. For a spectrum monitoring receiver, the system is defined as the RF preselector, RF downconverter, and IF conditioning modules including all interfaces between the RF IN connector on the RF preselector module front panel and the IF IN connector on the digitizer front panel.

Note

This attribute is not supported on a MIMO session.

You do not need to use a selector string if you want to configure this attribute for all signal instances. Specify the signal name in the selector string if you want to configure or read that signal instance. Refer to the Selector String topic for information about the string syntax.

The default value is N/A.
