RE: FDA Laser Requirements

Hi, Rich: I believe it's a typo error there. It should read as 1002.1, 21CFR1002.1(c) and Table 1 show the Applicability. Regards, Steve Hsu Sr. Quality Engineer Pine Photonics Communications s...@pinephotonics.com From: richwo...@tycoint.com [mailto:richwo...@tycoint.com] Sent:

Military ESD Specs

Members, Does anyone know the applicable military specs (US) for personal ESD (PESD) and helicopter ESD (HESD) are? These are not covered in MIL-STD-461. Thanks Darrell Locke Advanced Input Devices This message is from the IEEE EMC Society Product Safety Technical Committee emc-pstc

RE: Ethernet coax connection

The one-point connection od the 10 Base- coax shield is specified by IEEE standard 802.3. In my (2000) revision, it is e.g. in paragraph 8.7.2.2., page 158. to prevent the building up of voltages that may result in undue hazard to connected equipment or to persons. However, when

New countries that will accept the CE Mark

RE: Ethernet coax connection

I seem to recall that -years ago- IBM had an interface DC voltage spec. IBM required that BEFORE attaching a building-to-building interface cable to an EUT, that a DC voltage measurement be made between the shield of the cable and the EUT chassis. If the voltage exceeded 1.5V (I think) the

RE: Ethernet coax connection

ANSI/IEEE 802.3 specifies 10Base2 earthing at some point along the cable, but not at any node. 10Base2 nodes typically are an isolated (DC/DC + level shifter) 9-volt part of the PBWA with a high resistance connection to chassis. [RF radiation is higher and RF immunity is lower than 10BaseT.

Need 230VAC-115VAC 500VA Step-down Isolation Transformer with UL, cUL, and CE

Hi! I apologize if this is an inappropriate question for this forum. I am trying to select the above component for a product we are designing. I have found transformers with no approvals, one with UL and cUL, but not CE. Any advice on where to look or how to select such a component would be

Dual LISN vs Single LISN...

Hello Group, I am considering purchasing a dual LISN (two LISN networks within a single metal enclosure). Having used single LISNs for years, I am concerned that the dual LISN may be problematic for internal crosstalk/noise due to the close proximity of the independent LISN networks within the

Austel approved modem

Hello, We are looking for a source for an Austel approved modem (56K) for an Australian customer. The form factor for this modem could be one of the three following packages. I will list them in order of preference: 1. A cPCI compatible card. 2. A rackmountable, stand-alone unit powered

RE: Ethernet coax connection

I knew that I was headed for trouble when I responded to Ken Javor original question about EMI frustrations with 10Base2 Ethernet. I figured the safety guys would pummel me a little - and I accept the comments. However, I couldn't resist since I have experienced the same EMI frustrations.
