40dB Fall Time returns the fall time of the acquired signal at which transmit power drops 40 dB below average power. When you set the PowerRamp Averaging Enabled property to True, this parameter returns the mean of the 40dB fall time computed for each averaging count. This value is expressed in seconds.

You do not need to use a selector string to read this result for the default signal and result instance. Refer to the Selector Strings topic for information about the string syntax for named signals.
