The 434 is a analog storage scope with two independent storage areas on the screen. It has a bandwith of 24 MHz and uses a tunnel diode in its trigger circuit. The storage is done in the CRT itself, by trapping charge on a special fine grid of isolated pads behind the phosphor where the electron beam is then blocked or released.
There is a chopped two channel system and the fastest sweep time is 20nS/div. An option for a tube with higher sensitivity at high writing speeds was available too.
