Power meters for Energy Efficiency measurements

2009-07-22 Thread emc-p...@ieee.org
Hello everyone, We are currently researching power meters to perform Energy Efficiency measurements for our products and have been looking at Voltech PM1000+ and Xitron 2801/2802 meters. Has anyone used these and can give some feedback on them or any experience with other brands and would

VCCI Market Sampling Request

2009-07-22 Thread emc-p...@ieee.org
Hi Group, I have a question on the VCCI market sampling requests from VCCI. A company has received a request for VCCI to send their product to Japan and they will test it to verify it meets the requirements. The company never did sell this product to Japan and they never plan to. They just

General Cost of EMC Testing: RESULTS

2009-07-22 Thread emc-p...@ieee.org
We didn’t get as many replies as we would like, but it was surprising how similar the cost was at different labs. Most labs charge more for testing in a Chamber; especially if they have a large chamber for RE RI testing. Labs which use an OATS generally cost less per hour but the testing takes

I agree that it's not clear what it covers (hence the OP), and additional comment/guidance in new standard would be useful. Clause 4.1 of EN 50371 states: If the average power emitted by apparatus operating in the frequency band 10 MHz - 300 GHz is less than or equal to 20 mW and the

Adam, Thank you for your feedback. I think that I've seen that application. Is that produced by Passmark? Carl On Wed, Jul 22, 2009 at 7:38 AM, Rudd, Adam ar185...@ncr.com wrote: We use an application called BurnInTest. If you copy it’s “endpoint” application to an accessory PC

Hello Steve, EN 50371:2000 is indeed a LVD harmonised standard and, and as you already observe, for the RTTED article 3.1a (health and safety of the user). It applies to safety relating to RF Exposure or Specific Absorbsion Rate (SAR). For Europe, it should be applied in conjunction with

We use an application called BurnInTest. If you copy it’s “endpoint” application to an accessory PC and set its network module into advanced mode you can specify a network load level between the two. It also has a built in scrolling H pattern as well as CPU, memory, hard disk, and video stress

You are probably right, but in my mind it is still not clear and I don't think you can talk about unwritten and implying as a truth. It always bothers me when a standard which obviously can be clear is not. Perhaps its replacement, 62479, will be clearer. The other generic standard, 62311, is very

Rob I believe that EN 50371 is only applicable to intentional transmitters. EN 50371 is applicable from 10 MHz, but EN 62311 is applicable from 0 Hz. Section 5.2 of EN 50371 discusses how to test transmitters intended for use with external antennas. - the unwritten alternative being

Steve, as you are aware, the standard 50371 is a generic EMF standard which covers equipment not covered by a product or product-family standard (whose power does not exceed 20 mW). The product standards that I am aware of cover EAS, RFID, household appliances, mobile phones, wireless networks,
