EFFECTIVE ISOTROPIC RADIATED POWER CLAUSE 5.2.1
EIRP is calculated by method described under sub clause 7.2.1.2, using following formulae;
P = A + G + 10 log (1/x);

NOTE:
1. Measurements were done on low & high channels, but plots depicting the worst case are submitted in the test report.
2. The spurious emissions were done with different settings, using the relevant pre-amplifiers for the relevant frequency
ranges. This is the reason that the graphs show different noise levels.
