Well, I've got it now, although I haven't tested it yet.
And geez, I certainly scored with this one. I bought it from a guy whose dad was a technician. And obviously a very meticulous one, because he kept the manual in good condition. He had since passed away and the son had no use for the scope.
And what's better, he had another scope that he put up for auction and didn't sell. He only wanted $50 for it.
It was a dual trace, 20 Mhz, solid state, bwd 530A. It had one probe, and a manual! As soon as I got home, I fired it up and hooked it up to the calibration signal. Yep... a nice square wave. I then connected it to a battery and tested the DC... that worked too. So satisfying to see that green dot fly past at varying speeds depending on the time/div setting!
So, in total, $70 AUD and I get a 10Mhz single trace and a 20Mhz dual trace scope. For that sort of price you would only get a multimeter if you got it new, and I notice that Dick Smith is selling a 20MHz CRO for $399, and a 10MHz CRO for $128.
One question... I will need to connect the little alligator clip on the scope to the car's ground, correct?
And another question... do you think these scopes will work ok for testing/debugging a small basic stamp circuit? My first aim is to build an instantaneous fuel economy measuring circuit that will take the injector and speed sensor information and compute l/100km. I intend to use the basic stamp 2.
Thanks for all the help!
BTW I edited this because it originally came out wrong, it made it sound like I took pleasure in someone else's passing, which certainly wasn't the case at all. Considering the seller had been jerked around by someone else previously who wanted it posted for $50, I'm happy it worked out well for both of us.
