converting dBm to uV/m
dBm significant the logarithm relation to Power (mW). In case of field
strength or voltage (mV) you have to multiplication with 20. Take a look at: http://www.sengpielaudio.com/calculator-volt.htm http://www.nobbi.com/conversion.htm and very good: http://en.wikipedia.org/wiki/Decibel Regards, Ralf -- Vy 73 es 55 de Ralf, DL2MRB E-Mail: www.hamradioboard.de |
