FetchMeasurement(string, double, out double, out double)

Specifies a selector string comprising of the result name. If you do not specify the result name, the default result instance is used. Example:
""
""
"result::r1"
You can use the BuildResultString(string) method to build the selector string .

Specifies the timeout for fetching the specified measurement. 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. This value is expressed in seconds.

Upon return, contains the rise time of the acquired signal that is the amount of time taken for the power envelope to rise from a level of 10 percent to 90 percent. This value is expressed in seconds. When you set the SetAveragingEnabled(string, RFmxWlanMXPowerRampAveragingEnabled) method to True , this parameter returns the mean of the rise time computed for each averaging count. This value is expressed in seconds.

Upon return, contains the fall time of the acquired signal that is the amount of time taken for the power envelope to fall from a level of 90 percent to 10 percent. This value is expressed in seconds. When you set the PowerRamp Averaging Enabled method to True , this parameter returns the mean of the fall time computed for each averaging count. This value is expressed in seconds.
