Exact Mathematical Derivation for +51 dBm
Step 1: P(mW) = 10^(51 / 10) = 10^(5.10) = 125,892.541 mW
Step 2: P(W) = 125,892.541 mW ÷ 1,000 = 125.893 Watts
Step 3: V_RMS (@ 50Ω) = √(1.259e+2 W × 50 Ω) = 79.3387 V RMS (158.0 dBμV)
Step 2: P(W) = 125,892.541 mW ÷ 1,000 = 125.893 Watts
Step 3: V_RMS (@ 50Ω) = √(1.259e+2 W × 50 Ω) = 79.3387 V RMS (158.0 dBμV)
