Cannnot think of a better subject. I Just bought two. (accidently), found them on eBay for under $200. They are averaging around$300 now.
My Experience so far with this AWG
I have soooo tried to avoid these "big old tanks" My habit is to open them up because I read and learned abut how getting something used, and the person's experience was a bunch of cockroaches came out. I have had spiders and dead bug colonies. About opening it up. It is finichy because of the braided wire around each end of the cover. It was a real b..to get it back together. It had been calibrated that expired in Sept 2017 from a reputable firm that does that stuff.
It uses a 3.5 inch floppy disk to create your own custom waveforms. I still had some. There are floppy disk to USB adaptors that can be found.
Being so old, I just went ahead and attached the drive right to the side of the unit
Why an AWG old and a tank?
1.) I was looking for something that I could check a quality of a 200MHz scope.
2.) looking at Rigol/Hantek/ etc could only find similar pricing for 40 to 60MHz AWG, for over 100MHz I was seeing over $1,000 USD and higher up to $2,00 USD, even used...
3.) I dreaded getting something so big and heavy, and a CRT era. but I downloaded the manual measured and re-created the weight.. At this point I said maybe.
4.) At the Tektronics site, I learned that it had been i production back as far as 1994, but they were still selling them right up to 2006. Not so bad. perhaps the cllincher was they still had the most recent firmware updates downloadable, and the price.
a 250MHz, Tektronix relatively recent for under $300 shipped to my door? fine..I had to completely redo the teest gear shelves to accomodate the beast!
