The Tektronix 2225 is a 50 MHz dual-channel analog scope.
It has a single timebase with a magnifier that allows displaying normal and magnified traces together on the screen, but has no delay feature, only an X position control.
The Y inputs feature a x10 magnifier that decreases bandwidth to 5 MHz but increases sensitivity to 0.5 mV/Div.
The 1104A battery can be used to operate the 2225 without mains power.
