RFmxSpecAn SEM Fetch Upper Offset Power VI

Selector String specifies a selector string comprising of the signal name, result name, and offset number. If you do not specify the signal name, the default signal instance is used. If you do not specify the result name, the default result instance is used.

Example:

"offset0"

"signal::sig1/offset0"

"result::r1/offset0"

"signal::sig1/result::r1/offset0"

You can use the RFmxSpecAn Build Offset String2 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.

Timeout specifies the timeout, in seconds, for fetching the specified measurement. Set this value to an appropriate time, longer than expected for fetching the measurement. A value of -1 specifies that the VI waits until the measurement is complete. The default value is 10.

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

Peak Relative Power returns the peak power in the upper (positive) offset segment relative to the integrated or peak power of the reference carrier.

When you set the SEM Ref Type property to Integration, the reference carrier power is the total power in the reference carrier. When you set the SEM Ref Type property to Peak, the reference carrier power is the peak power in the reference carrier.

Peak Frequency returns the frequency, in Hz, at which the peak power occurred in the offset segment.

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

Total Absolute Power returns the upper (positive) offset segment power measured.

The power is measured in dBm when you set the SEM Power Units property to dBm, and in dBm/Hz when you set the SEM Power Units property to dBm/Hz.

Total Relative Power returns the power in the upper (positive) offset segment relative to the integrated or peak power of the reference carrier.

When you set the SEM Ref Type property to Integration, the reference carrier power is the total power in the reference carrier. When you set the SEM Ref Type property to Peak, the reference carrier power is the peak power in the reference.

Peak Absolute Power returns the peak power measured in the upper (positive) offset segment. The power is measured in dBm when you set the SEM Power Units property to dBm, and in dBm/Hz when you set the SEM Power Units property to dBm/Hz.

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