F.11 Peak method

The peak method can be used when frequencies with unwanted peak emissions are identified during pre-scan. The method does not provide an estimate of TRP.

For each peak emission frequency identified during pre-scan, measure peak EIRP or power density as follows:

1. Move EUT and test antenna to the same position where the peak emission is recorded during the pre-scan.

2. Move the EUT around the position and test antenna orientation to find the final peak EIRP or power density.

3. The measured peak power density or EIRP shall be used to demonstrate conformance.

NOTE: Peak EIRP is the linear sum of two orthogonal polarised components.
