Exact Mathematical Derivation for +54 dBm
Step 1: P(mW) = 10^(54 / 10) = 10^(5.40) = 251,188.643 mW
Step 2: P(W) = 251,188.643 mW ÷ 1,000 = 251.189 Watts
Step 3: V_RMS (@ 50Ω) = √(2.512e+2 W × 50 Ω) = 112.0689 V RMS (161.0 dBμV)
Step 2: P(W) = 251,188.643 mW ÷ 1,000 = 251.189 Watts
Step 3: V_RMS (@ 50Ω) = √(2.512e+2 W × 50 Ω) = 112.0689 V RMS (161.0 dBμV)
