Pardon me, but I'm not sure I understand why the cage should be isolated instead of grounded. Wouldn't 'grounding' the cage provide better 'isolation' from test station to test station, instead of just bouncing or reflecting the signal, like I imagine an isolated cage would do? Currently we avoid crosstalk by planning what test stations are placed where, so that we don't put unshielded tests nearby critical spurious tests on another product line, for example. But as we get crowded, waiting for our new 'triple the size' production facility to be ready, we are running out of room to space our test stations adequately. In our new building, there will be no competing product line test benches backing on to each other - they will just have to worry about the ones to either side... Thanks. -----Original Message----- From: Sauer, Steven T.

The critical thing would be to ensure that the washer completely covers the hole made in the screen for the lag bolt to pass through. One side note, the cage doesn't need to be grounded, it should be isolated. There are some commercially available products that may fit your needs, such as a portable "tent" that is made of aluminum poles and EMI shielded material. If I can find that information, I'll pass it along later.... Good Luck.

I seen this successfully used for a high voltage faraday cage and it is also used on our EMC compliance test room.

RF screen or something that we can mount and ground between the benches to reduce what we call 'crosstalk'. ---------------------------------------------------------------------------- ----- Technet Mail List provided as a free service by IPC using LISTSERV 1.8d To unsubscribe, send a message to [log in to unmask] with following text in the BODY (NOT the subject field): SIGNOFF Technet To temporarily halt delivery of Technet send the following message: SET Technet NOMAIL Search previous postings at: www.ipc.org > On-Line Resources & Databases > E-mail Archives Please visit IPC web site (http://www.ipc.org/html/forum.htm) for additional information, or contact Keach Sasamori at [log in to unmask] or 847-509-9700 ext.5315 ---------------------------------------------------------------------------- ----- --------------------------------------------------------------------------------- Technet Mail List provided as a free service by IPC using LISTSERV 1.8d To unsubscribe, send a message to [log in to unmask] with following text in the BODY (NOT the subject field): SIGNOFF Technet To temporarily halt delivery of Technet send the following message: SET Technet NOMAIL Search previous postings at: www.ipc.org > On-Line Resources & Databases > E-mail Archives Please visit IPC web site (http://www.ipc.org/html/forum.htm) for additional information, or contact Keach Sasamori at [log in to unmask] or 847-509-9700 ext.5315 ---------------------------------------------------------------------------------
