dBmV
A power measurement of ‘x dBmV’ indicates that a particular
signal is x dB greater than (‘above’) 1 millivolt in 75 ohms. A
negative dBmV value indicates that the signal is x dB less than
(‘below’) 1 millivolt in 75 ohms.
To convert x millivolts to dBmV:
dBµV
Similarly, a measurement of ‘x dBµV’ indicates that the signal is x
dB above one microvolt in 75 ohms.
To convert x microvolts to dBµV:
To convert dBmV to dBµV, add 60 to the dBmV reading:
dBm
A measurement of ‘x dBm’ indicates that a particular signal is x dB
greater than (‘above’) 1 milliwatt. A negative dBm value indicates
that the signal is x dB less than (‘below’) 1 milliwatt.
To convert x milliwatts to dBm:
