Introduction This article reviews MIL-STD-461 CS101 including the updates contained in revision “G” the current version. The test title “Conducted Susceptibility, Power Leads” pretty well defines the test, where interference is applied to the power input of the Equipment Under Test (EUT). During application of the interference the EUT is monitored to verify acceptable … [Read more...]
Proposed Changes to CISPR SC I Standards
Are you familiar with CISPR 32 and CISPR 35? CISPR 32 was originally published in 2012, followed by a pair of corrigenda and then the 2nd edition was published in 2015. CISPR 32 replaced CISPR 13 (Broadcast receivers emissions) and CISPR 22 (ITE emissions). In the EU CISPR 32 is published as EN 55032 and it has superseded EN 55013 and EN 55022. By now you should all be … [Read more...]
UNECE Regulation 10: The Type Approval Process
Welcome to the first in a series of blogs on UNECE Regulation 10. In the first few blogs we will cover the fundamentals of Type Approval and the processes involved in obtaining an 'E' mark. Subsequent blogs will cover the various EMC test requirements set out in UNECE Regulation 10, Revision 5 (hereafter referred to as R10.05) in detail. Testing is only part of the … [Read more...]
Review of the EMC Filters Kit from Würth Elektronik
Some weeks ago I received one unit of the EMC-Filter kit from Würth Elektronik (Order Code: 744998), a very nice and useful kit for industry and academia (Fig. 1). Fig. 1. The EMC-Filter kit from Würth Elektronik (Order Code: 744998) If you are interested in filtering conducted emissions, this is a great kit for evaluation of components and topologies in both differential … [Read more...]
Substitution Source Measurements
In today’s EMC testing world testing is very often automated, using well calibrated test equipment. The operator sets up the EUT and support equipment, sets up the test equipment, fires up the software on the computer designed to automate the test, clicks on “Go” and sits back to watch the blinking lights. After a while the test is complete and a file is generated containing … [Read more...]

Do your people really know how to perform a conducted emissions test to ANSI C63.4 or CISPR 32?
Oftentimes when a new person is hired to perform conducted emissions testing in a laboratory they know little about EMC and even less about how to perform a test. There is a training period where the new person learns how to perform a test using whatever software the lab has been using. The new person is well trained in how to perform the test with the automation working, … [Read more...]
EMI / EMC Issues in an Industrial Automation System
A discussion between Peter Thomas (PROFIBUS/PROFINET expert) and Keith Armstrong (EMC expert), in December 2017 Peter: Hello Keith. I have spent today visiting an industrial plant in the UK. Whilst there I took the opportunity to look at several areas from an EMI point of view. I wondered what you thought of the following: I list below a few observations following … [Read more...]
Do Not Miss the EMC+SIPI 2018 Symposium!
