13. NUMBER OF HOPPING FREQUENCY
13.1 Block Diagram Of Test Setup
13.2 Limit
Frequency hopping systems in the 2400-2483.5 MHz band shall use at least 15
channels.
13.3 Test procedure
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 = 100kHz. VBW = 300kHz. Sweep = auto; Detector
Function = Peak. Trace = Max hold.
3. Allow the trace to stabilize. It may prove necessary to break the span up to sections. in
order to clearly show all of the hopping frequencies. The limit is specified in one of the
subparagraphs of this Section.
4. Set the spectrum analyzer: Start Frequency = 2.4GHz, Stop Frequency = 2.4835GHz.
