RFmxCDMA2k QEVM Fetch Constellation Trace VI

Selector String specifies a selector string comprising of the signal name and result name. 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. The default value is "" (empty string).

Examples:

""

"signal::sig1"

"result::r1"

"signal::sig1/result::r1"

You can use the RFmxCDMA2k 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.

Timeout specifies the timeout for fetching the specified measurement. This value is expressed in seconds. 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.

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

Constellation returns the array of complex chips of the corrected signal on which the QEVM measurements are performed. You can use these chips to obtain the constellation diagram.

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