Objective/Summary/Conclusion:
Objective:
Confirm compliance with required standards and Bose margins.

Summary:
The worst-case configuration is when the AUX IN cable is grounded to the shield room wall with the charger operating from 120
VAC/60 Hz and charging a discharged battery.

Conclusion:
The combination of charger and BOSEBuild2 pass regulatory and Bose recommended margins with 3.7 dB below the regulatory
limit at 0.3885 MHz.

Test setup verification check(s):
Test Setup/Procedure:
1 Set up EMI receiver for standard conducted emissions configuration. Use transient limiter.
2 Plug reference source (TN1380) directly into EUT LISN mains outlet. Set source spacing to 500 kHz.
3 Compare resulting sweeps with reference plots file on computer desktop (file name is "Conducted Emissions Verification
   xxxxxx", where xxxxxx represents latest plot date). File is located on desktop and also in "Henry_Room" folder ->
   "Conducted reference plots". Any data/plots taken for comparison to reference should be recorded in this section.
4 If desired, use the Excel file below to compare the four marker points (four max hold peak, one QP, and one average
   measurement) of the measured verification plots with the reference plots. It is sufficient to store a copy of the verification
   plots along with the product test results in the Integrity database.
5 Measurements may be made by any method (manual, semi-automated software, screen capture). Record the method
   used.
