4.2 FREQUENCY RANGE
4.2.1 LIMITS
EN300 328 clause 4.3.3
fL > 2,4 GHz and fH < 2,4835 GHz
4.2.2 TEST PROCEDURE
Test EUT in normal conditions, then repeat in extreme conditions.
Measurement RBW = 100kHz, VBW ≥ 100 kHz, average mode with 60 second sweeps selected.
Pre-test the 3 modulation to find GFSK and 8DPSK is worse case, so only record GFSK and 8DPSK test
data.
4.2.3 TEST SETUP
Test EUT in normal conditions, then repeat in extreme conditions.
Measurement RBW = 100kHz, VBW ≥ 100 kHz, average mode with 60 second sweeps selected.
Pre-test the 3 modulation to find GFSK and 8DPSK is worse case, so only record GFSK and 8DPSK test
data.
