Exact Mathematical Derivation for +57 dBm
Step 1: P(mW) = 10^(57 / 10) = 10^(5.70) = 501,187.234 mW
Step 2: P(W) = 501,187.234 mW ÷ 1,000 = 501.187 Watts
Step 3: V_RMS (@ 50Ω) = √(5.012e+2 W × 50 Ω) = 158.3015 V RMS (164.0 dBμV)
Step 2: P(W) = 501,187.234 mW ÷ 1,000 = 501.187 Watts
Step 3: V_RMS (@ 50Ω) = √(5.012e+2 W × 50 Ω) = 158.3015 V RMS (164.0 dBμV)
