Returns the EVM measurement of the data channel.

Inputs/Outputs
Selector String
—
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 RFmxTDSCDMA Build Signal String VI to build the selector string.
Instrument Handle In
—
Instrument Handle In specifies the RFmx session refnum. Instrument Handle In is obtained from the RFmxInstr Initialize NIRFSA VI.
Timeout (s)
—
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 (no error)
—
error in describes error conditions that occur before this node runs. This input provides standard error in functionality.
RMS Data Phase Error (deg)
—
RMS Data Phase Error returns the RMS of the data phase error, averaged over all active time slots and all averaging iterations. This value is expressed in degrees.
RMS Data Magnitude Error (%)
—
RMS Data Magnitude Error returns the RMS of the data magnitude error, averaged over all active time slots and all averaging iterations. This value is expressed as a percentage.
Instrument Handle Out
—
Instrument Handle Out passes a reference to your RFmx session to the next VI.
RMS Data EVM (%)
—
RMS Data EVM returns the RMS of the data EVM, averaged over all active time slots and all averaging iterations. This value is expressed as a percentage.
Peak Data EVM (%)
—
Peak Data EVM returns the peak data EVM among all active time slots and averaging iterations. This value is expressed as a percentage.
Data Rho
—
Data Rho returns the data rho value, averaged over all active time slots and all averaging iterations.
error out
—
error out contains error information. This output provides standard error out functionality. |
