I like single shot mode for scope standby, too. A number of times I forgot that scope was in single shot and spent some time trying to find out 'what is wrong with my scope', but I still think that is a better way, because you do not have to mess up any settings. It did surprise me that life of a CRT was in the range of 40 k to 80 k hours; my gut feel was that it was around 10 k. I never had a CRT to die on me, it was only passives, mostly electrolytics. While I was still working with tube scopes never had any tube to die on me, though that was a matter of luck, and at that company there was security guard who would come around and turn everything off and write you up even for soldering iron that was left on. When I was talking about keeping a scope on all the time, I did say 'working ' (as opposed to scope from collection used for hobby work). When paid to do work one should not spend too much time trying to save pennies and skip over dollars. Regards Miroslav Pokorni ----- Original Message -----

The company I work for has sold custom flat panel displays to anothermajor US test equipment manufacturer (use your imagination here). About 5 yearsget in a situation of having to replace backlights mulitiple times during theCRTs, but I digress.one would burn up a tube in roughly 4 to 8 years if the instrument was left on(something not all that abundant as was shown this last summer) and life of otherparts like electrolytic caps, I tend to shut everything off when not in use, orat work for 13 years now, and even when it's on, if I'm not using it for ashort bit, I will put the scope in single shot mode to shutoff the beam andrental instrument. Hopefully, when used only when needed, the instrument willlast a lifetime :>) |
