I have a dBW value and dBW I understand to normally be given as representing a RMS Power (however this is not specificically ever stated and I am told its just assumed?)
from dBW to Watts = 10^(dBW/10)
This then gives RMS power in Watts
At what point do I convert this from a RMS to a peak value:
1. Multiply RMS Power in Watts by sqrt(2) before using Voltage = sqrt(Power*50)
2. Or multiply the result from Voltage = sqrt(Power*50) by sqrt(2)
because they give two different values...
