It's 20MHz and we think donated by Darcy.
Made in West Germany, circa 1990.
See instruction manual: File:Hameg hm203-7.pdf
Specifications
- 2 channels, max 1 mV / div. sensitivity.
- Component Tester
- Timebase: 0.1 s/div. to 20 ns/div.
- Variable holdoff
- Alternate Triggering
- Triggering: DC - 40 MHz

Warnings
When the X-Y button is depressed, the X signal is derived from channel 2 instead of scanning left to right.
The manual warns:
Should both input voltages be missing or fail in the X-Y mode, a very bright light dot is displayed on the screen. This dot can burn into the phosphor at a too high brightness setting (INTENS. knob) which causes either a lasting loss of brightness, or in the extreme case, complete destruction of the phosphor at this point.
