The screen is just over 3" with a bright blue trace. It has automatic focus. All the regular controls are on the front.
Plus a few on the side. Note the holes where the handle used to be mounted.
The rear, with the power cord removed
At 50Mhz I was able to get both channels to give exactly the same display with the same input signal. Here they are overlaid.
One channel inverted
Doing a good job displaying a pretty low-amplitude signal
With the cover on it's about 17" long
No excessive wear here, either
The manual has instructions for operation, specifications AND schematics.
