How to Convert Dbv to Dbm?
DBu or dBv (Decibel Reference Voltage 0.775 V, Amplitude Ratio) — Absolute Rms Voltage in Decibels Relative to the Reference Voltage (600 Ohms ∙ 0.001 W)1/2 =...
dBu or dBv (decibel reference voltage 0.775 V, amplitude ratio) — absolute RMS voltage in decibels relative to the reference voltage (600 Ohms ∙ 0.001 W)1/2 = (0.6) 1/2 ≈ 0.775 V ≈ –2.218 dBV because it is derived from a 600 Ohms load dissipating 0 dBm or 1 mW.
What is dBm and dBV?
dBm is a power ratio relative to 1mW, dBu and dBV are voltage ratios, relative to 0.775V and 1V, respectively.
How do you convert to dBm?
Decibels are used to represent the ratio of two quantities of power: db = 10 log P1/P0 . In the case of dbm the reference power P0 is 1 milliwatt : dbm = 10 log P1/1mw. Inverting this equation gives the power in terms of the reference power: P1= P010db/10. In the case of dbm the equation is P1= 1mw·10dbm/10.
