RE: Radiated Emission Testing - Solution?

Hi Tim- I whole heartedly agree with your comments vis a vis the unsuitability of the OATS as a rigorous test platform. I also completely agree with your comments on test repeatability. I would offer a "light at the end of the tunnel" for you. A while back Matt Aschenberg, a stats guy and myself p

RE: protective earthing test

The CSA approach is that you base the test current on the branch circuit overcurrent protection ahead of the product when installed as intended because the available current will determine the heating of the grounding and bonding path. In general, the breaker rating is multiplied by 2 and the test

Can anyone point me to where I might find the source of the commonly used USB port symbol ( looks like a horizontally oriented three prong pitch fork). I am trying to establish if there are any restrictions or requirements for the use of this symbol. Regards Donald McElheran Ross Video Ltd.

Re: EMC Test report generation

In one of my previous lives, I was EMC Engineer/Lab Manager at a commercial EMC Compliance lab. We had the following process for report generation: 1) The time charged for report generation was 3 hours, and I did not see any customer complaining. 2) The package generated for Class-B systems to

RE: Weaknesses in Today's Police Radar

Ed, Occasionally, a "technicality" is all that is needed for a local jurisdiction to decide they don't have a case. I was "radared" by an officer standing on the side of the road with his radar gun; a second officer was standing next to him. I went to the court house to get a copy of the ticket

Good People, I know this is off-topic, but I do not feel like being a good person today. Ed has excellent advice. Engineers tend to apply logic to law; but in many legal events, the only logic available is to "follow the money". In California, traffic court has no jury, and is heard by a commiss

Dear group, Regarding medical devices, I knew protective earthing test was performed differently between EN 60601-1 and CAN/CSA 22.2 No.601-1. In particular, I read some articles talking of a 30 Amps, 2 minutes test, instead of 25 Amps, 5 seconds. Now, I've got CAN/CSA 22.2 N0 601-1, both 1990 and
