2.2 DESCRIPTION OF THE TEST MODES
To investigate the maximum EMI emission characteristics generates from EUT, the test system was
pre-scanning tested base on the consideration of following EUT operation mode or test configuration
mode which possible have effect on EMI emission level. Each of these EUT operation mode(s) or
test configuration mode(s) mentioned above was evaluated respectively.
Test software: FCC tool
The test softeware was used to control EUT work in continuous TX mode, and select test channel,
Wireless mode as below table
No.
Test model descrption
1
Low channel GFSK
2
Middle channel GFSK
3
High channel GFSK
Note:
1. All the test modes can be supply by battery, only the result of the worst case recorded in the
report. GFSK mode is worst mode.
2. For radiated emission, 3 axis were chosen for testing for each applicable mode.
3. The EUT used fully charge battery when tested.
4. During the test, the dutycycle>98%, the test voltage was tuned from 85% to 115% of the
Nominal rate supply votage, and found that the worst case was the nominal rated supply
condition, So the report just shows that condition’s data
5. We finally chose to test the right earphone of the sample, because the circuit of the left
earphone and the right earphone are the same
