Webfield strength at the measurement antenna must have been: FS = (-12.1 dBm) – (31-3) + 77.2 – 16.9 + 20log(2300) = +87.4 dBμV/m. If an equation is required to convert field … Web4 Conversion formulae On the basis of free-space propagation, the following conversion formulae may be used. Field strength for a given isotropically transmitted power: E P t – 20 log d 74.8 (7) Isotropically received power for a given field strength: P r E – 20 log f …
WebExample 1: calculate the noise power in a 2000Hz wide receiver at 7MHz with a -1dBi antenna at 1000m distance from the source, if the broadband source has a field strength of 30μV/m in 9000Hz bandwidth at 30m distance from the source (FCC 15.209 limit). Answer: -103dBm (S4 in S-meter terms, and well above expected lowest ambient noise). WebResult: EIRP, or effective isotropically radiated power, or equivalent isotropically radiated power, is a measurement of output power in one direction from an ideal, one dimensional …
