O-scope fun fun
I’m finally getting around to replacing my long lost oscilloscope. If you’re hunting for one, ebay has a great selection. Here’s a rather nice intro to the used scope market
. I decided to hunt for a tektronix since they’ve been around for so long. The 465 series appears to be a great choice, but then I discovered a the 7000 series. These things have optional plug in modules that will make this older scope deal with ghz bandwidth or even become a spectrum analyzer. Of course, the mainframe design means that they’re pretty damn big, but this isn’t an issue in my workshop.
I picked up a 7633 complete with a few modules for half the going price of a 465. It should be interesting to check out when it shows up. The 7633 was released in 1970 and wasn’t replaced in the model line until 1990. It’ll do 100Mhz out of the box, and with three module bays, you can feed it six traces if you like. The scope can even export waveforms to a PC (hopefully via serial). These are considered to be very high quality, but just don’t get the love that the 465 does, probably due to their monster size.
