Every final lot of OsteoSelect® DBMV Putty is tested in an in viva rat model for osteoinductive potential. It is unknown how the osteoinductivity potential in the rat model correlates with human clinical performance.

The dBm figure is the power related to a specific carrier bandwidth.(BW) Normaly, for a carrier , this is the power in the 3 dB bandwidth. If you use a spectrum analyser to measure the carrier power, you must make sure to use a resolution bandwidth which is greater than the carrier BW, but not so wide it takes in the power of any adjacent carrier.

4.0 Therefore, 107 dBuV = 0 dBm in a 50 W system 5.0 Using this as the scale factor: dBm + 107 dB = dBuV * Must be entered in Watts (0.001 or 1x10-3 W = 1 mW) * Must be entered in Volts (0.000001 or 1x10E-6 V = 1uV)

decibels relative to one milliwatt (dBm): The expression dBm is used to define signal strength in wires and cables at RF and AF frequencies. The symbol is an abbreviation for "decibels relative to one milliwatt," where one milliwatt (1 mW) equals 1/1000 of a watt (0.001 W or 10 -3 W). This unit is commonly used in test laboratories.

dBm Calculator: As we know Decibel in dB can be calculated as: dB= 20log(V1/V2)= 10log(P1/P2) If we put P2 = 1mW = .001 watt then it becomes dBm: dBm= 10log(p1/.001) Means dBm is calculated when the input power is considered as 1mW

Conversion of dBm to dBmV dBm is defined in Equation 3. POUT is measured in mW. The dBm is referenced to 1mW. Equation 3 does depend on impedance of the load as shown in Equation 4. Most RF equipment has a 50Ω load or input impedance. Equation 3 is still valid for any load impedance including 75Ω. Power depends on load impedance.

Example: Convert +10 dBm to dBmV. A. 50 Ohm Reference Impedance: dBmV = +10 dBm + 47 dB = +57 dBmV. B. 75 Ohm Reference Impedance: dBmV = +10 dBm + 48.75 dB = +58.75 dBmV
