From: r_jungert@xxxxxxxxxxx To: perry.qu@xxxxxxxxxxxxxxxxxx Subject: FW: [SI-LIST] Re: SMA cable for TDR Date: Tue, 28 Oct 2008 14:41:02 -0700 Perry. Check out Tensolite Accuphase. It works to 40ghz last I heard. They make cables for testing products with 35ps TDR test equipment. We did a test box for 65 channel cable product and used this cable in the test unit and it did a fine job up to 35ps. Tensolite is now Carlisle Interconnect Technologies. They make probes and cables for Tektronix, Agilent and Boeing so its good quality stuff. http://www.tensolite.com/v2/index.asp Good luck Richard Jungert > Subject: [SI-LIST] Re: SMA cable for TDR > Date: Tue, 28 Oct 2008 16:16:16 -0500 > From: Perry.Qu@xxxxxxxxxxxxxxxxxx > To: weirsi@xxxxxxxxxx; zabinski.patrick@xxxxxxxx; Mark.Randol@xxxxxxxxxx; > Chris.Cheng@xxxxxxxx > CC: si-list@xxxxxxxxxxxxx > > Thanks everyone for the suggestions on/off list.
