RFmxLTE ModAcc Fetch CSRS EVM (Array) VI

Selector String specifies a selector string comprising of the signal name, result name, and subblock 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. The default value is "subblock0".

Example:

"subblock0"

"signal::sig1/subblock0"

"result::r1/subblock0"

"signal::sig1/result::r1/subblock0"

You can use the RFmxLTE Build Subblock 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.

Mean RMS CSRS EVM returns the array of mean values of RMS EVMs calculated on Reference Signal (RS) resource elements over the slots specified by the ModAcc Meas Length property. When you set the ModAcc EVM Unit property to Percentage, the measurement is returned in percentage. When you set the ModAcc EVM Unit property to dB, the measurement is returned in dB.

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