Syntax
public int FetchPdsch1024QamEvm( string selectorString, double timeout, out double meanRms1024QamEvm )
Public Function FetchPdsch1024QamEvm ( selectorString As String, timeout As Double, <OutAttribute> ByRef meanRms1024QamEvm As Double ) As Integer
Parameters
- selectorString
- Type: SystemString
Specifies a selector string comprising of the result name, subblock number, and carrier number. If you do not specify the result name, the default result instance is used. Example:
"subblock0/carrier0"
"result::r1/subblock0/carrier0"
You can use the BuildCarrierString(String, Int32) method to build the selector string. - timeout
- Type: SystemDouble
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 method waits until the measurement is complete. - meanRms1024QamEvm
- Type: SystemDouble
Upon return, contains a mean value of the calculated RMS EVMs on all 1024QAM modulated PDSCH resource blocks over the slots specified by the SetMeasurementLength(String, Int32) method. When you set the SetEvmUnit(String, RFmxLteMXModAccEvmUnit) method to Percentage, the measurement is returned in percentage. When you set the ModAcc EVM Unit method to dB, the measurement is returned in dB.
Return Value
Type: Int32Returns the status code of this method. The status code either indicates success or describes a warning condition.
