The '''R7912''', introduced in 1974, achieved a bandwidth of 500 MHz with a [[7A19]] vertical amplifier plug-in. It was also possible, like in the [[7904]] scope, to access the CRT deflection plates directly through a [[7A21N]] plug-in and achieve a bandwidth of 1 GHz, albeit at reduced sensitivity (4 V/Div) and loss of triggering and readout functions. | The '''R7912''', introduced in 1974, achieved a bandwidth of 500 MHz with a [[7A19]] vertical amplifier plug-in.

The reading bem operates differently depending on the output mode. In non-store (TV) mode, the reading beam scans the target in a horizontal format similar to that used in conventional television systems, and a video output compatible with TV monitors is generated. In Digital mode, the reading beam scans the target vertically, in 512 discrete steps for each of 512 horizontal positions. Waveforms are converted to digital, stored in memory, and can be read by a computer. | |||
The R7912 had a proprietary digital interface. A card for interfacing to a DEC PDP-11 was available. | The R7912 had a proprietary digital interface. A card for interfacing to a DEC PDP-11 was available. | ||
