Conducted Emissions Converter
Convert conducted emission units between dBµV, dBµA, dBm, and dBmA at a LISN impedance.
Use this when: You need to correlate voltage and current measurements on power lines during CISPR conducted emissions testing.
Key formula
dBµA = dBµV − 20 × log₁₀(Z) · dBm = dBµV − (10·log₁₀(Z) + 90)Example: 107 dBµV at 50 Ω → 0 dBm, 73 dBµA (34 dB below dBµV at 50 Ω LISN)

Offset: dBµV = dBm + 107 at this impedance
