Well, ?the catalogs from the mid to late 60's show Tek scopes around fighters, subs (if I recall correctly), etc. ?Maybe they were trying to impress military types that were used to seeing G ratings? ?A real flimsy guess... ? That's a lot of acceleration for a big piece of test gear! -Dave From: "Rob" To: TekScopes@... Sent: Thursday, January 24, 2013 10:16:57 PM Subject: RE: [TekScopes] Re: Tentative 647 scan? ? Really nice. Once again the depth and team spirit of this forum shines. ? Curious¡. The specification indicates that the scope can take 20G¡¯s acceleration in any plain for a total of 12 hits. I assume that the 11ms duration is to give an idea of the impulse imparted for said acceleration. Anyway, these numbers seem to indicate that this scope could have been used to drive pilling and/or break concrete and be ¡°oK¡± afterwards. I realize the analogy is a bit boastful, nonetheless for a piece of electronics to take that kind of abuse and keep functioning is impressive. More impressive to publish it as such. ? So to the question, some place along the line those kind of specifications appear to have been dropped and/or were no longer important. (well at least I don¡¯t see them in the catalogues for the 7000 series scopes I concentrate on). ? By way of learning for me. Why were these kind of specifications important for the earlier scopes? What made them less important in later scopes? Do specifications like that exist for later scopes? I looked in a few 7000 series manuals and did not see anything resembling acceleration specs so again I assume not¡ However, my sample is extremely small so making any conclusions would be foolhardy. Hopefully some of you that have been in the industry for years will have better insight. ???? ? In any event, thanks as always for the bandwidth and the free education. Rob ????? ?
