Parameters

selectorString

Type: SystemString
Specifies a selector string comprising of the result name, and subblock number. If you do not specify the result name, the default result instance is used. Example:
"subblock0"
"result::r1/subblock0"
You can use the BuildSubblockString(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.

meanRmsEvm

Type: SystemDouble
Upon return, contains the array of mean values of RMS EVMs calculated on the PDSCH data symbols 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.

meanRmsQpskEvm

Type: SystemDouble
Upon return, contains the array of mean values of RMS EVMs calculated on all QPSK modulated PDSCH resource blocks over the slots specified by the ModAcc Meas Length method. When you set the ModAcc EVM Unit 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.

meanRms16QamEvm

Type: SystemDouble
Upon return, contains the array of mean values of RMS EVMs calculated on all 16 QAM modulated PDSCH resource blocks over the slots specified by the ModAcc Meas Length method. When you set the ModAcc EVM Unit 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.

meanRms64QamEvm

Type: SystemDouble
Upon return, contains the array of mean values of RMS EVMs calculated on all 64 QAM modulated PDSCH resource blocks over the slots specified by the ModAcc Meas Length method. When you set the ModAcc EVM Unit 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.

meanRms256QamEvm

Type: SystemDouble
Upon return, contains the array of mean values of RMS EVMs calculated on all 256 QAM modulated PDSCH resource blocks over the slots specified by the ModAcc Meas Length method. When you set the ModAcc EVM Unit 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.
