Power supply (V):
    Vnominal = 3 Vdc

Type of power supply = DC voltage supplied by the internal batteries “2 x 1.5Vdc AA”.
Type of antenna = Integral antenna




TEST FREQUENCIES:
Transmitter channel: 915 MHz


CONDUCTED MEASUREMENTS
The equipment under test was set up in a shielded room and it is connected to the spectrum analyser.


RADIATED MEASUREMENTS
All radiated tests were performed in a semi-anechoic chamber. The measurement antenna is situated at a
distance of 3 m for the frequency range 30 MHz-1000 MHz (30 MHz-1000 MHz Bilog antenna) and at a
distance of 1m for the frequency range 1 GHz-10 GHz (1 GHz-18 GHz Double ridge horn antenna).
For radiated emissions in the range 1 GHz-10 GHz that is performed at a distance closer than the
specified distance, an inverse proportionality factor of 20 dB per decade is used to normalize the
measured data for determining compliance.
The equipment under test was set up on a non-conductive (wooden) platform one meter above the ground
plane and the situation and orientation was varied to find the maximum radiated emission. It was also
rotated 360º and the antenna height was varied from 1 to 4 meters to find the maximum radiated
emission.
Measurements were made in both horizontal and vertical planes of polarization.

Whichever is the lesser attenuation

RESULTS:
The situation and orientation was varied to find the maximum radiated emission. It was also rotated
360º and the antenna height was varied from 1 to 4 meters to find the maximum radiated emission.
Measurements were made in both horizontal and vertical planes of polarization.
All tests were performed in a semi-anechoic chamber at a distance of 3 m for the frequency range 30
MHz-1000 MHz and at distance of 1m for the frequency range 1 GHz-10 GHz.
The field strength is calculated by adding correction factor to the measured level from the spectrum
analyser. This correction factor includes antenna factor, cable loss and pre-amplifiers gain.
