The subject is a 4 layer design that originally passed EMC testing which was then reduced to a 2 layer design and subsequently failed. We’ll go into the main findings of an initial EMC design review I did on the 4 layer design, then go into the changes needed to get the 2 layer boa...
so within or near a large city it makes testing on an OATS next to impossible. The ambient noise also prevents automated emissions testing because human intervention is required to distinguish between noise from the EUT and background noise. Long story short – testing at a SAC goes much faste...
We are an agent for a chamber manufacturer now – let me know if you would like more information. Best regards, Andy. Reply But as I read the some EMC pre compliance testing documents I understand that the DUT must be placed on the wooden table which means a non conductive table and th...
I'm doing some basic EMC pre compliance testing on a small (~10cm square) control unit. I've got a suitably sized die cast metal box which i plan to use as an ad-hoc test "chamber", but i'm wondering what antenna i should use to to collect the radiated emissions from the EUT a...
The current probe measurements were below the noise floor, so I didn’t pick up any major emissions issues. The flicker/harmonics testing will be discussed in a later section. Bring 3 different LED drivers for comparison I had a preferred driver due to cost and availability, but I brought ...
Four VMware Clusters were used to support the solution and testing environment: •Infrastructure Cluster (vCenter, Active Directory, DNS, DHCP, SQL Clusters, VMware View Connection Servers, View Composer, and Nexus 1000V Virtual Switch Manager appliances, etc.) •VDA Clusters (2) (Windows 7 ...
EMC testing is a just a different kind of feature set that your design needs to include. Without an EMC functional specification, you’re leaving a pass or fail at an EMC lab up to chance. Is it any coincidence then, that according toIntertek(one of the largest lab groups in the world...
