The only tek 22xx I ever had any experience with was new in '84, a pure analog 100 mhz dual trace 2235, had a shite crt that tek would not replace in warranty, so I eventually ordered the crt ($550 at the time) and put it in myself. Generally it worked well but as usual with a tek, the input attenuators go way out of calibration and developed severe frequency response errors, really bad by '93 or so, and by then tek had done that same thing they always do 5 years after the last one rolls off the line, all the spares went to the landfill. I sent it to the transmitter site. AFAIK, it still works, but if I saw a square wave being displayed as a square wave, I'd go get my glasses fixed. My own Hitachi V-1065 works well yet today and it is pushing 30 years old. The timebase is out of calibration about 3 or 4%, but voltages are still dead on, as are the displays of a square wave. Best $1200 I ever spent for any piece of test equipment, ever. If something should destroy it, I'd buy another one just like it tomorrow.
The only Hitachi scope I wouldn't touch is the V-1085, the trigger circuit doesn't. > Jason > ------------------------------------------------------------------------ > ------ Live Security Virtual Conference > Exclusive live event will cover all the ways today's security and > threat landscape has changed and how IT managers can respond. > Discussions will include endpoint security, mobile security and the > latest in malware threats. > http://www.accelacomm.com/jaw/sfrnl04242012/114/50122263/ > _______________________________________________ > Emc-users mailing list > [email protected] > https://lists.sourceforge.net/lists/listinfo/emc-users Cheers, Gene -- "There are four boxes to be used in defense of liberty: soap, ballot, jury, and ammo.
