= ×
Wherein, R
denotes the output impedance of the channel and must be a
specific value; therefore, when the output impedance is HighZ, dBm
cannot be used.
For example, when the output impedance is 50Ω and the amplitude is
1.768Vrms (namely 5Vpp), press · in the numeric keyboard to select
dBm to convert the amplitude to the corresponding value (17.9601dBm)
in dBm.
