 Remark:
 Factor = Antenna Factor + Cable Loss – Pre-amplifier.
RESULT: PASS
Note:
        Other emissions from 1G to 25 GHz are considered as ambient noise. No recording in the test report.
        Factor = Antenna Factor + Cable loss - Amplifier gain, Over=Measure-Limit.
        The “Factor” value can be calculated automatically by software of measurement system.
        All test modes had been tested. The GFSK modulation is the worst case and recorded in the report.

RESULT: PASS
Note: The factor had been edited in the “Input Correction” of the Spectrum Analyzer. So the Amplitude of test
plots is equal to Reading level plus the Factor in dB. Use the A dB(μV) to represent the Amplitude. Use the F
dB(μV/m) to represent the Field Strength. So A=F. All test modes had been pre-tested. The GFSK modulation
is the worst case and recorded in the report.

11. NUMBER OF HOPPING FREQUENCY
11.1. MEASUREMENT PROCEDURE
The EUT shall have its hopping function enabled. Use the following spectrum analyzer settings:
1. Span: The frequency band of operation. Depending on the number of channels the device supports, it may
be necessary to divide the frequency range of operation across multiple spans, to allow the individual
channels to be clearly seen.
2. RBW: To identify clearly the individual channels, set the RBW to less than 30% of the channel spacing or
the 20 dB bandwidth, whichever is smaller.
3. VBW ≥ RBW. Sweep: Auto. Detector function: Peak. Trace: Max hold.
4. Allow the trace to stabilize.

12. TIME OF OCCUPANCY (DWELL TIME)
12.1. MEASUREMENT PROCEDURE
The EUT shall have its hopping function enabled. Use the following spectrum analyzer settings:
1. Span: Zero span, centered on a hopping channel.
2. RBW shall be≤channel spacing and where possible RBW should be set >> 1 / T, where T is the expected
dwell time per channel.
3. Sweep: As necessary to capture the entire dwell time per hopping channel; where possible use a video
trigger and trigger delay so that the transmitted signal starts a little to the right of the start of the plot. The
trigger level might need slight adjustment to prevent triggering when the system hops on an adjacent channel;
a second plot might be needed with a longer sweep time to show two successive hops on a channel.
4. Detector function: Peak. Trace: Max hold.
5. Use the marker-delta function to determine the transmit time per hop.
6. Repeat the measurement using a longer sweep time to determine the number of hops over the period
specified in the requirements. The sweep time shall be equal to, or less than, the period specified in the
requirements. Determine the number of hops over the sweep time and calculate the total number of hops in
the period specified in the requirements, using the following equation:
  (Number of hops in the period specified in the requirements) = (number of hops on spectrum analyzer) ×
(period specified in the requirements / analyzer sweep time)
7. The average time of occupancy is calculated from the transmit time per hop multiplied by the number of
hops in the period specified in the requirements.

13. FREQUENCY SEPARATION
13.1. MEASUREMENT PROCEDURE
The EUT shall have its hopping function enabled. Use the following spectrum analyzer settings:
1. Span: Wide enough to capture the peaks of two adjacent channels.
2. RBW: Start with the RBW set to approximately 30% of the channel spacing; adjust as necessary to best
identify the center of each individual channel.
3. Video (or average) bandwidth (VBW) ≥ RBW.
4. Sweep: Auto. e) Detector function: Peak. f) Trace: Max hold. g) Allow the trace to stabilize.
Use the marker-delta function to determine the separation between the peaks of the adjacent channels.
