A unit used to express power level in decibels relative to one milliwatt.

An absolute power level described in decibels referenced to 1 mW. 0 dBm is equivalent to 1 mW.

Power in dB relative to 1 mW.

A ratio of decibel strength to 1 milliwatt.

decibels with respect to one milliwatt

A standard reference for power in audio work using a milliwatt (mW, 1000th of a watt). Decibels themselves are only a ratio based on the resistance/impedance of a circuit, the dBm gives a fixed reference/constant of decibels referenced to 1 milliwatt to then obtain fixed values. 0 dBm=1mW.

Decibel reference to 1 miliwatt; 0 dBm equals one miliwatt

dBm is a measure of power and is defined as the ration in dB relative to 1mW e.g. 1mW = 0dBm adn 1W = 30dBm.

Decibels referred to 1 milliwatt (mW). A measurement of relative power related to 1mW. For example, 20dBm corresponds to 1020dBm/10 = 100mW.

dB rating which indicates the number of decibels a signal is higher or lower than 1mW

Decibels referenced to one milliwatt of power. dBm is used in communication work as a measure of absolute power values. Zero dBm equals one milliwatt.

A logarithmic measure of the electrical power referred to one milliwatt.

Relative measure of signal power where the reference 0 dBm is equal to one milliwatt. See also decibel.

Optical power referenced to 1 milliwatt. (0dBm = 1 milliwatt, 10dBm = 10 milliwatts, 20dBm = 100 miliwatts, etc.)

Decibel relative to 1 milliwatt

Decibels compared to one milliwatt. A wireless networking device's transmit and receive powers are often measured in decibel strength compared to one milliwatt of power. The higher the dBm, the greater the device's transmit or receive power.

Decibel (milliwatts). 10 * log10 (power in milliwatts). For example, 2 milliwatts is 10 * log(base 10)2 = 10 * 0.3010 = 3.01 dBm

Decibels referenced to 1 milliwatt, it must be specified with load impedance (usually 50 ohms).

A common engineering parameter to compare, in dB, an RF signal level to the specific reference value of 1 milliwatt.

Ratio of the power of a signal to 1 milliwatt

Unit of measure of the power level of a signal expressed in decibels above 1 milliwatt.

The voltage measured on a 600ohm resistor relative 0 dBm. 0 dBm is defined as the voltage (.775V) measure on a 600ohm resistor powered with 1 mW.

dBm stands for decibels referenced to 1 milliwatt (mW) and is the unit of measure for the absolute power output of a wireless system.

Decibels reference to one milliwatt (mW); an "absolute" unit used to measure signal power (transmit power output or received signal strength).

Decibels relative to 1 milliWatt

Decibels with respect to 1 milliwatt. A unit of RF signal strength used in satellite work and other communications applications.

Measure of audio signal level, within or between electronic equipment. This measurement is taken using specialist test equipment.

A ratio of decibels per milliwatt.

Decibels measured in milliwatts.

A measure of power output. It is the power referenced to a signal of 1mW. Decibels are logarithmic scale and an increase of 3dB is twice the power so 3dBm=2mW, 6dBm=4mW, 9dBm=8mW and so on. see Useful tools.

Decibel based on 1 milliwatt. Ratio of two power levels, in which the second is one milliwatt.

Decibel referenced to 1 milliwatt into a 50 Ohm impedance (usually) 0 dBm = 1 mW

(dBm) A power level compared with 1 milliwatt. Learn more about DBM...

Decibels referenced to one milliwatt. An absolute unit used to measure signal power, as in transmitter power output, or received signal strength.

A technique for expressing a power measurement in logarithmic form using 1 mW as a reference.

An abbreviation for decibels referred to one milliwatt. A term used to denote power level; i.e. 0 dBm is equal to 1 milliwatt.

Decibels above one milliwatt. A measure of power equal to 10 times the common logarithm of the ratio of a given power to 0.001 watt

The level of a signal in dB relative to 1 m W (0 dBm).

Power measured in dB relative to one milliwatt.

a term expressing an electrical power level, referenced to 1 milliwatt (i.e., 0 dBm = 1 mW). Originally, dBm was used to express the power dissipated in telephone applications with 600-ohm impedances, but it is not necessarily referenced to a particular impedance.

Decibel reference to 1 miliwatt; 0 dBm equals 1 miliwatt.

Decibel referenced to a milliwatt.

dB referenced to 1 milliwatt. To convert into an equivalent voltage level, the impedence must be specified. For example, 0 dBm into 600 ohms gives an equivalent voltage level of 0.775V, or 0 dBu; however, 0 dBm into 50 ohms, for instance yields an equivalent voltage of 0.24 V. Since modern audio engineering is concerned with voltage levels, as opposed to power levels in the early years of telephone, the convention of using a reference level of 0 dBm is academic. But in the A/V industry, many people still refer to 0.775Vrms (600 r) as 0 dBm, which should be more accurately called 0dBu.

A measure of power based upon the decibel scale, but referenced to the milliWatt: i.e. 1dBm = .001 Watt. dBm is often used to describe absolute power level where the point of reference is 1 milliWatt. In high power applications the dBW is often used with a reference of 1 Watt.

Decibels relative to a power level of 1mW.

Decibel, Milliwatt; decibel referenced to one milliwatt into 50 ohms (typical for RF systems).

A measure of power in communications: the decibel in reference to one milliwatt ( 0 dBm = 1 milliwatt and -30 Bm = .001 milliwatt).

Abbreviation for decibel relative to milliwatt.

Bm is an abbreviation for the power ratio in decibel (dB) of the measured power referenced to one milliwatt (mW). It is used in radio, microwave and fiber optic networks as a convenient measure of absolute power because of its capability to express both very large and very small values in a short form. dBm (or dBmW) and dBW are independent of impedance (as opposed to dBV which is dependent, for example).
