Sources for Terminations
I believe that a question did come up somewhere concerning where oneDeane Kidd sells Tek 011-0049-01 feedthrough terminators for about $10 when he has them. Probemaster has one, model 1055, that sells for about $33. They tend to turn up in scope cart drawers and probe pouches - often you can buy a scope cart for less than the value of the drawer contents :-) |

Let us not forget that not all terminations are equal. I will take example

of few terminations that Tek supplies: 011-0049-01 is good up to 500 MHz, then 011-0099-00 good probably to 250 MHz and then precision (0.1%) 011-0129-01 is good up to 100 kHz (that is kilo, not a typo). Probably ranking behind Tek is Pomona then comes Pasternak, then Radio Shack ... I suggest to try your terminator on a TDR, a reflectometer and your target cable; quality of termination shows real good. Regards Miroslav Pokorni -----Original Message-----

When I was in the Navy in the mid-1970's, we would order the 011-0049-
00 using the FSN. Amazing what the military can do to you when they decide to get something cheaper. We didn't get Tek terminations. Instead, we got these low-bidder things that were all chromed (or nickel, or whatever), few of them measured exactly 50 ohms and most of them fell apart in our hands with the first use! I think we'd rather have had a $500 hammer! And if you wanted the REAL thing from Tek, you had to order them "open purchase" (or direct from a commercial vendor vs. throught the normal military supply system) which was always a real hassle in justification, etc. And even then, if your ordered something like that "open purchase", often our own supply folks would do us the "favor" of discovering that the part we wanted had an FSN and we'd end up with the inferior parts anyway!

should see purchasing agents in commercial companies, especially those with 'empire building' mindset. It must be at these 'purchasing workshops' that they get told the first object of game is to avoid buying a brand name product. They would spend couple of hours to come up with some off brand (probably 'purchasing agent network' exchanges information on low bidders) and then you have to spend another few hours re-evaluating product that you already specified, all that to save few bucks or find out that product does not meet requirements, but those details never stand in the way of purchasing agent claims of how much money they saved to company. By the way, regarding this $500 hammer. When military was dredged over coals for buying $3500 coffee makers, Delta Airlines bought this same coffee makers for $4500 a piece; it is that Delta bought 3 pieces, and military ordered 5, so military got a price brake. Those were not your Mr. Coffee machines, these were flight-worthy devices. Regards Miroslav Pokorni -----Original Message-----
