Radiated Power Calculator
Use this tool to convert and correlate radiated RF power levels by comparing ERP and EIRP (expressed in dBm or mW) with field strength measurements (in dBµV/m) taken at 3 or 10 meters.
| Unit | Value |
|---|---|
| EIRP (mW) | 0 |
| EIRP (dBm) | 0 |
| ERP (mW) | 0 |
| ERP (dBm) | 0 |
| dBµV/m at 3m | 0 |
| dBµV/m at 10m | 0 |
Explanation:
- EIRP (Effective Isotropic Radiated Power) is the power radiated as if by an ideal isotropic antenna.
- ERP (Effective Radiated Power) is measured relative to a half-wave dipole.
- The factor 1.64 (or +2.15 dB) accounts for the gain difference between these reference antennas.
This tool helps with:
Converting dBµV/m measurements from EMC tests into equivalent ERP/EIRP values in dBm or mW.
Comparing EMC test results against radiated power limits defined in compliance standards.
Extrapolating emission limits across different measurement distances (from 10m to 3m) for RF transmitters, receivers, and transceivers.
