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.

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.
4. Detector function: Peak. Trace: Max hold.
5. Use the marker-delta function to determine the transmit time per hop.
6. Using the following equation:

                                                                                             Page 58 of 69

14.3. PRELIMINARY PROCEDURE OF LINE CONDUCTED EMISSION TEST
1.   The equipment was set up as per the test configuration to simulate typical actual usage per the user’s
     manual. When the EUT is a tabletop system, a wooden table with a height of 0.8 meters is used and is
     placed on the ground plane as per ANSI C63.10 (see Test Facility for the dimensions of the ground plane
     used). When the EUT is a floor-standing equipment, it is placed on the ground plane which has a 3-12
     mm non-conductive covering to insulate the EUT from the ground plane.
2.   Support equipment, if needed, was placed as per ANSI C63.10.
3.   All I/O cables were positioned to simulate typical actual usage as per ANSI C63.10.
4.   All support equipments received AC120V/60Hz power from a LISN, if any.
5.   The EUT received DC charging voltage by adapter which received 120V/60Hzpower by a LISN..
6.   The test program was started. Emissions were measured on each current carrying line of the EUT using a
     spectrum Analyzer / Receiver connected to the LISN powering the EUT. The LISN has two monitoring
     points: Line 1 (Hot Side) and Line 2 (Neutral Side). Two scans were taken: one with Line 1 connected to
     Analyzer / Receiver and Line 2 connected to a 50 ohm load; the second scan had Line 1 connected to a
     50 ohm load and Line 2 connected to the Analyzer / Receiver.
7.   Analyzer / Receiver scanned from 150 kHz to 30MHz for emissions in each of the test modes.
8.   During the above scans, the emissions were maximized by cable manipulation.
9.   The test mode(s) were scanned during the preliminary test.

Then, the EUT configuration and cable configuration of the above highest emission level were recorded for
reference of final testing.


14.4. FINAL PROCEDURE OF LINE CONDUCTED EMISSION TEST
1.   EUT and support equipment was set up on the test bench as per step 2 of the preliminary test.
2.   A scan was taken on both power lines, Line 1 and Line 2, recording at least the six highest emissions.
     Emission frequency and amplitude were recorded into a computer in which correction factors were used
     to calculate the emission level and compare reading to the applicable limit. If EUT emission level was
     less –2dB to the A.V. limit in Peak mode, then the emission signal was re-checked using Q.P and Average
     detector.
3.   The test data of the worst case condition(s) was reported on the Summary Data page.
