Duration calculation in Power Amplifier Protection

Question

There are avgDuration and peakDuration setting in PA protection function. 
 As for avgDuration, what does "L" mean? 
 If the txSampleRate=122.88MHz, avgDuration is set to 10, then what is the time of duration in seconds? 
 From the formula, there is "5" added, does it mean the least duration is 5 seconds? 
 Could you teach me how to calculate the real duration time? 
 Thanks.

L is not part of the equation and its a typo, please ignore, below is the correct equation. We will correct this in the upcoming release of the UG. 
 
 The duration is in time, as you can see the inverse of frequency is time and we are multiplying with a factor of 2^(avgduration+5). 5 has nothing to do here and its an approximation to get the measurement duration number. 
 Let me know if you have any follow up questions.)
