Exact Mathematical Derivation for +86 dBm
Step 1: P(mW) = 10^(86 / 10) = 10^(8.60) = 398,107,170.554 mW
Step 2: P(W) = 398,107,170.554 mW ÷ 1,000 = 398,107.171 Watts
Step 3: V_RMS (@ 50Ω) = √(3.981e+5 W × 50 Ω) = 4461.5422 V RMS (193.0 dBμV)
Step 2: P(W) = 398,107,170.554 mW ÷ 1,000 = 398,107.171 Watts
Step 3: V_RMS (@ 50Ω) = √(3.981e+5 W × 50 Ω) = 4461.5422 V RMS (193.0 dBμV)
