The EMC Shop stocks and rents this test equipment, allowing customers to preliminary evaluate their products before attempting certification. The IEC/EN 61000-4-6 test standard should be purchased, read and followed to develop a suitable test plan and effectively evaluate your product.
IEC 61000-4-6 is a standard for testing electromagnetic disturbances along data and power lines that run to and from your product (DUT = Device Under Test). While intimidating to decipher the 89 pages of edition 5 of EN/IEC 61000-4-6, it's testing techniques are simple and will help flush out other problem areas that arise in EMC testing. Most of our custommers usually call in, rent equipment and contact us with the equipment in hand. Dialing in the test setup, sequence or anything else is usually quickly resolved to get testing underway.
IEC 61000-4-6 Procedure, Setup & Testing
-
- In lab or in place?
- Determine test levels and coupling devices
- Performance Criteria
- Description of the EUT exercising method
- Setup equipment and run calibration
- Identify nearby and external contributors (if any)
- Run test and identify problem areas
- The recovery time of the EUT if necessary
- Troubleshoot accordingly
Most of our customers will simply place the test generator on a bench, ground everything, and be off and rolling. There are diagrams avaialble that specify spacing, insulation, placement of the generator, etc... We have found that in most cases, these aren't detrimental in precompliance measurements when following IEC 61000-4-6. The test standard is long and detailed, covering different test setups, injection methods, procedures and more. The EMC Shop can support this effort with information on your DUT and surrounding auxilary equipment.
