Exact Mathematical Derivation for +58 dBm
Step 1: P(mW) = 10^(58 / 10) = 10^(5.80) = 630,957.345 mW
Step 2: P(W) = 630,957.345 mW ÷ 1,000 = 630.957 Watts
Step 3: V_RMS (@ 50Ω) = √(6.310e+2 W × 50 Ω) = 177.6172 V RMS (165.0 dBμV)
Step 2: P(W) = 630,957.345 mW ÷ 1,000 = 630.957 Watts
Step 3: V_RMS (@ 50Ω) = √(6.310e+2 W × 50 Ω) = 177.6172 V RMS (165.0 dBμV)
