4.4 CARRIER FREQUENCIES SEPARATED
4.4.1 LIMITS
Frequency hopping systems operating in the 2400-2483.5 MHz band may have hopping channel
carrier frequencies that are separated by 25 kHz or two-thirds of the 20 dB bandwidth of the
hopping channel, whichever is greater, provided the systems operate with an output power no
greater than 125 mW.
carrier frequencies that are separated by 25 kHz or two-thirds of the 20 dB bandwidth of the
hopping channel, whichever is greater, provided the systems operate with an output power no
greater than 125 mW.
4.4.2 TEST PROCEDURES
1. Remove the antenna from the EUT and then connect a low RF cable from the
antenna port to the spectrum.
2. Set the spectrum analyzer: RBW >= 1% of the span (set 100 kHz). VBW >=
RBW , Span = 6MHz. Sweep = auto; Detector Function = Peak. Trace =
Max,hold.
Max,hold.
3. Allow the trace to stabilize. Use the marker-delta function to determine the
separation between the peaks of the adjacent channels. The limit is specified in
one of the subparagraphs of this Section. Submit this plot.

Remark：
Pre-test the 3 modulation to find GFSK and 8DPSK is worse case, so only record GFSK
and 8DPSK test data.
