Key Details
The test report covers two primary EMC measurement categories as required by FCC CFR 47 Part 15 Subpart B: Conducted Emission and Radiated Emission. Both test categories returned a Pass result, confirming that the ETENWOLF S0 does not exceed permissible electromagnetic interference limits for unintentional radiators placed on the US market.
| Test Category | Section in Report | Result |
|---|---|---|
| Conducted Emission | Section 3 (Pages 8–12) | Pass |
| Radiated Emission | Section 4 (Pages 13–20) | Pass |
Conducted Emission Test Summary
The conducted emission test assessed interference transmitted through the power lines of the EUT. The test setup, instrument configuration, measurement uncertainty, applicable limits, and full test data are documented in Section 3 of report WTH25H09245622E. All measured values were within the limits prescribed by FCC CFR 47 Part 15 Subpart B for Class B unintentional radiators.
Radiated Emission Test Summary
The radiated emission test assessed electromagnetic energy radiated from the EUT into free space. The test receiver setup, EUT placement, corrected amplitude and margin calculations, and full test data are documented in Section 4 of report WTH25H09245622E. All measured values, after applying antenna correction factors and cable loss corrections, were within the prescribed FCC limits with positive compliance margins.
Test System Configuration
Section 2 of the report details the complete test system configuration, including justification for the configuration selected, EUT exercise software, any equipment modifications, basic test procedures, a description of test auxiliary equipment, and the application of the decision rule used to determine pass/fail outcomes.
| Configuration Item | Reference Section |
|---|---|
| Justification | Section 2.1 |
| EUT Exercise Software | Section 2.2 |
| Equipment Modifications | Section 2.3 |
| Basic Test System & Procedures | Section 2.4 |
| Test Auxiliary Description | Section 2.5 |
| Decision Rule Application | Section 2.6 |
Standards & Compliance
The ETENWOLF S0 was tested in accordance with the following regulatory standard governing unintentional radiators in the United States:
| Standard | Full Title | Scope |
|---|---|---|
| FCC CFR 47 Part 15 Subpart B | Code of Federal Regulations, Title 47, Part 15, Subpart B – Unintentional Radiators | Conducted and radiated emission limits for electronic devices sold in the United States |
FCC Part 15 Subpart B applies to all digital devices that may unintentionally generate and radiate radio frequency energy. Compliance with this standard is mandatory for all electronic products placed on the US market. The test report form used was TRF FCC CFR 47 Part 15 Subpart B-EMC-001-V01, and the overall test result was Pass.
Measurement uncertainty was evaluated and documented separately for both the conducted emission (Section 3.1) and radiated emission (Section 4.1) test sections, in accordance with good laboratory practice and accreditation requirements.
