RFmxBT_ModAccFetchDEVM

This parameter specifies the RFmx session refnum. This parameter is obtained from the RFmxInstr_Initialize function.

This parameter specifies a Selector String comprising of the signal name and the 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).
Example:
"signal::sig1"
"result::r1"
"signal::sig1/result::r1"
You can use the RFmxBT_BuildSignalString function to build the selector string.

This parameter 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 function waits until the measurement is complete. The default value is 10.

This parameter returns the peak of the RMS DEVM values computed on each 50us block of the EDR portion of the EDR packet. When you set RFMXBT_ATTR_MODACC_AVERAGING_ENABLED attribute to True, it returns the maximum of the peak RMS DEVM values computed for each averaging count. This value is expressed in percentage.

This parameter returns the peak of the DEVM values computed on symbols in the EDR portion of the EDR packet. When you set the ModAcc Averaging Enabled attribute to True, it returns the maximum of the peak symbol DEVM values computed for each averaging count. This value is expressed in percentage.

This parameter returns the 99th percentile of the DEVM values computed on symbols of the EDR portion of all measured EDR packets. This value is expressed in percentage.
