Exact Mathematical Derivation for +84 dBm
Step 1: P(mW) = 10^(84 / 10) = 10^(8.40) = 251,188,643.151 mW
Step 2: P(W) = 251,188,643.151 mW ÷ 1,000 = 251,188.643 Watts
Step 3: V_RMS (@ 50Ω) = √(2.512e+5 W × 50 Ω) = 3543.9289 V RMS (191.0 dBμV)
Step 2: P(W) = 251,188,643.151 mW ÷ 1,000 = 251,188.643 Watts
Step 3: V_RMS (@ 50Ω) = √(2.512e+5 W × 50 Ω) = 3543.9289 V RMS (191.0 dBμV)
