Use & Relationship
The EMITR provides the data and information necessary to evaluate compliance of an equipment or subsystem with its electromagnetic interference (EMI) control requirements based on MIL-STD-461, including the discussion of recommended corrective actions, if needed.
a. This Data Item Description (DID) contains the format, content, and intended use information for the data deliverable resulting from the work task described for the EMITR in paragraph 5.1 of MIL-STD-461.
b. This DID is related to DI-EMCS-80199C, Electromagnetic Interference Control Procedures (EMICP), and DI-EMCS-80201C, Electromagnetic Interference Test Procedures (EMITP).
c. DI-EMCS-80200C supersedes DI-EMCS-80200B.
Preparation Instructions
1Reference documents.The applicable issue of the documents cited herein, including their approval dates and dates of any applicable amendments, notices, and revisions, shall be as specified in the contract.
2Format.Contractor format is acceptable.
3Content.The EMITR shall contain the following:
3.1Administrative data.The EMITR shall contain an administrative section covering the following:
3.1.1Contract number.
3.1.2Authentication and certification of performance of the tests by a qualified representative of the procuring activity.
3.1.3Disposition of the Equipment Under Test (EUT).
3.1.4Description of the EUT, including its function, characteristics, intended installation, actual cable types (characteristics and construction details - see 4.3.8.6 of MIL-STD-461), and electrical current usage on each power input line.
3.1.5List of tests performed with pass/fail indications.
3.1.6Any approved deviations from contractual test procedures or limits previously authorized.
3.1.7Identification of Non-Developmental Items (NDI) and Government Furnished Equipment (GFE) that may be part of the EUT.
3.1.8Traceability of test equipment calibration.
3.1.9A reference to the approved EMI test procedure (EMITP).
3.2Detailed results.A separate appendix shall be prepared for each test. If deviations from an approved test procedure occurred during the test program, an additional appendix shall be provided with the "as run" procedures showing all red-lines and procuring activity concurrence. A separate appendix shall be provided for log sheets. Each test appendix shall contain the following factual data:
3.2.1Test equipment nomenclature, serial numbers, version of software used (if any), and calibration due date.
3.2.2Photographs or diagrams of the actual test set up and EUT, with identification.
3.2.3Transfer impedance of current probes.
3.2.4Antenna factors.
3.2.5Impedance values of Line Impedance Stabilization Networks (LISN).
3.2.6Identification of any suppression devices used to meet the contractual requirements, including schematics, performance data, and drawings.
3.2.7Sample calculations, such as conversions of measured levels for comparison against the applicable limit.
3.2.8The ambient radiated and conducted electromagnetic emission profile of the test facility, when necessary.
3.2.9Data, and data presentation, as specified in the "data presentation" sections of the individual test procedures of MIL-STD-461.Emissions data cannot be provided on one single sheet (plot). Provide a minimum frequency resolution of 1% or twice the measurement receiver bandwidth, whichever is less stringent, and a minimum amplitude resolution of 1 dB for each plot.
3.2.10Scan speeds.
3.2.11Measurement receiver bandwidths.
3.2.12Antenna polarization.
3.2.13Power line voltages, frequencies, and power factor.
3.2.14Low-noise amplifiers (LNA) compression points.
3.2.15Test susceptibilities and deviations from normal performance are not acceptable.However, when susceptibility indications or deviations from normal performance are noted in the EUT operation, a threshold level shall be determined where the susceptible condition or deviation is no longer present. These thresholds need to be documented for further assessment.
3.3Conclusions and recommendations.Conclusions and recommendations shall be provided, including results of the tests in brief narrative form, a discussion of any remedial actions already initiated, and proposed corrective measures required (if necessary) to assure compliance of the equipment or subsystem with the contractual EMI requirements.
