4.2 ANTENNA REQUIREMENT
The EUT antenna is PCB Printed antenna. Antenna gain is 3dBi .which accordance 15.203.is
considered sufficient to comply with the provisions of this section
considered sufficient to comply with the provisions of this section
4.3 OCCUPIED BANDWIDTH
4.3.1 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.
4.3.2 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: Span = approximately 2 to 3 times the 20dB bandwidth,
center on a hopping channel;
3. Set the spectrum analyzer: RBW >= 1% of the 20dB bandwidth (set 10kHz). VBW >=
RBW. Sweep = auto; Detector Function = Peak. Trace = Max Hold.
4. Mark the peak frequency and -20dB bandwidth.
5. bandwidth value is OBW value.
Remark:
Pre-test the 3 modulation to find GFSK and 8DPSK is worse case, so only record GFSK
and 8DPSK test data.
and 8DPSK test data.
