Seconds? Division? Thats fancy talk. When I mean antique I mean Korean? war.
Looks like it has untriggered sweep. By this I mean that it's very hard to get a stable waveform without careful fiddling of the vernier dial. (It might be synchronized sweep, which could exhibit a bit of a 'notch' on the vernier where it does lock.) Regardless, once one knows the frequency range of the various sweep switch settings one can get a very coarse (i.e. within 10-30%, that sort of thing) idea of the frequency by dialing up some number of full waveforms on the face and then back-calculating from the vernier setting. Not easy, but possible. I'm sure the squid techs would call you a pansy boy for not being able to extract frequency from their stone-age tool!
Allow me to suggest a useful adjunct, like a Fluke DMM. The 'scope will show you if you've got a good enough waveform to get a good frequency count off of, and the Fluke will tell you the number. (For audio frequencies.) My old Griefkit IO-102 had supposedly synchronized sweep, but it never worked. Just as the VTVM's higher voltage ranges were all out of whack. These were both assembled by my father, with me watching as a boy, and I still had the manuals. I took them fully apart and repeated the instructions, correctly this time. Both work well, now. Both have been semi-superseded by newer tools, like the Tektronix 2336 scope and the Fluke 83/87 DMM's. When the Tek crapped out a few years ago, however, the old scope was of great aid in repairing it. Dad's attention to detail is not mine. OTOH, somehow he could teach science to rooms full of pubescents, and be loved for it. (Whom I would have killed within days, I'm sure. Me not teacher. Ugh.) _Any_ scope is better than no scope. -- Jim _______________________________________ http://www.okiebenz.com For new and used parts go to www.okiebenz.com To search list archives http://www.okiebenz.com/archive/ To Unsubscribe or change delivery options go to: http://okiebenz.com/mailman/listinfo/mercedes_okiebenz.com
