My second scope was the wonderful Tektronix 455 - a great analog scope with lots of great features - about 100 times better than my first Soviet C112 scope. Reasons:
|Bandwidth||50 MHz||10 MHz|
|Number of channels||2||1|
|Z - modulation (beam intensity channel)||Yes||No|
|Screen size||Big||Very small|
|Trigger modes/sources/combinations of them||A lot||The basic ones|
|A truckload of other cool features||Yes||No|
I had to sell it to buy my current digital scope, but I remember it well 🙂 Good times...
If you need the manual, I have it in PDF form, just ask me for it.
Here are some photos - while looking for any pics, I couldn't find any. So, here are some pictures of the scopes innards:
Some nasty ASIC is under the heatsink...
A part is missing! They stole my parts!!!
Nice wavy routing 🙂
Note the mechanical connections to various control elements.
Note the funny delay line above.
