Note:
1. All readings are quasi-peak unless stated otherwise, using a QPA
bandwidth of 120kHz, with a 60 s sweep time. A video filter was
not used.
2. The field strength is calculated by adding the Antenna Factor,
Cable Factor & Preamplifier. The basic equation with a sample
calculation is as follows: Emission Level =Reading Level + Antenna
Factor + Cable Loss –Preamplifier Factor.
3. The other emission levels are 20dB below the official limits that are
not reported.
