RFmxSpecAn ACP Configure Offset Power Reference (Array) VI

Selector String specifies a selector string comprising of the signal name. If you do not specify the signal name, the default signal instance is used. The default value is "" (empty string).

Example:

""

"signal::sig1"

You can use the RFmxSpecAn Build Signal String VI to build the selector string.

Instrument Handle In specifies the RFmx session refnum. Instrument Handle In is obtained from the RFmxInstr Initialize NIRFSA VI.

Offset Reference Carrier specifies the array of carriers to be used as power reference to measure offset channel relative power. The offset channel power is measured only if you set the ACP Carrier Mode property of the reference carrier to Active. The default value is Closest.

Closest (0)	The measurement uses the power measured in the carrier closest to the offset channel center frequency, as the power reference.
Highest (1)	The measurement uses the highest power measured among all the active carriers as the power reference.
Composite (2)	The measurement uses the sum of powers measured in all the active carriers as the power reference.
Specific (3)	The measurement uses the power measured in the carrier that has an index specified by the ACP Offset Pwr Ref Specific property, as the power reference.

Offset Reference Specific specifies the array of carrier indices to use as the reference carrier for each offset channel. The power measured in this carrier is used as the power reference for measuring the offset channel relative power, when you set the Offset Power Reference Carrier parameter to Specific. The default value is 0.

error in describes error conditions that occur before this node runs. This input provides standard error in functionality.

Instrument Handle Out passes a reference of your RFmx session to the next VI.

error out contains error information. This output provides standard error out functionality.
