Exact Mathematical Derivation for +48 dBm
Step 1: P(mW) = 10^(48 / 10) = 10^(4.80) = 63,095.734 mW
Step 2: P(W) = 63,095.734 mW ÷ 1,000 = 63.096 Watts
Step 3: V_RMS (@ 50Ω) = √(6.310e+1 W × 50 Ω) = 56.1675 V RMS (155.0 dBμV)
Step 2: P(W) = 63,095.734 mW ÷ 1,000 = 63.096 Watts
Step 3: V_RMS (@ 50Ω) = √(6.310e+1 W × 50 Ω) = 56.1675 V RMS (155.0 dBμV)
