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:
| Parameter | Tektronix | C-112 |
|---|---|---|
| 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 |
| XY mode | Yes | No |
| Multimeter(Voltage, ohms) | No | Yes |
| 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.
