Calibration example of the EIRP
1. Antennas with known gains measure in the boresight direction.
| Pt［dBm］ | Effective radiated power (ERP) |
| Gt［dB］ | Antenna gain |
| Pt eirp［dBmeirp］ | Equivalent isotropically radiated power Pt [dBm] + Gt [dB] |
| Pr［dBm］ | Received power of RF connector part of Electromagnetic anechoic box through receiving antenna + coaxial cable |
2. Find the degree of antenna coupling.
| K［dB］ | Pt eirp［dBmeirp］－Pr［dBm］ |
3. Can be measured radiation electricity of measured device (EUT) in reception system same as calibration.
| P eirp［dBmeirp］ | Pread［dBm］＋K［dB］ |
