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