Gore will be my first choice and I am cheap enough to look for them in ebay :-D I also have good luck with Megaphase. But I think the launch head is my limitation in most cases not the cable itself. -----Original Message----- From: si-list-bounce@xxxxxxxxxxxxx [mailto:si-list-bounce@xxxxxxxxxxxxx]On Behalf Of QU Perry Sent: Tuesday, October 28, 2008 12:17 PM To: si-list@xxxxxxxxxxxxx Subject: [SI-LIST] SMA cable for TDR Hi, I plan to buy some dedicated SMA cables for my TDR measurement that was used to extract S parameters for serdes channels. Rise time about 40ps and 3 feet flexible cable will be ideal. Is there any specific vendor that you recommend ? I tried W L Gore but they are expensive. Please email me if you have any suggestions.
