Option 06 (first offered in 1975 catalog) adds offset voltage controls giving ±200 Div offset range. | Option 06 (first offered in 1975 catalog) adds offset voltage controls giving ±200 Div offset range. | ||
This option replaces the IDENTIFY buttons with DC offset controls, and adds a fourth "DC offset" position to the input coupling switch. | This option replaces the IDENTIFY buttons with DC offset controls, and adds a fourth "DC offset" position to the input coupling switch. | ||
The '''7A18A''' is mostly identical to the 7A18 predecessor, but replaces the custom low inductance potentiometers for gain and variable gain setting with a FET attenuator and regular potentiometers. | |||
The 7A18(A) uses a discrete front-end followed by [[M036|M36]] channel switch ICs for the vertical and trigger signals. | |||
The 200 MHz [[7A26]] and 400 MHz [[7A24]] share the same front panel layout and operation. | The 200 MHz [[7A26]] and 400 MHz [[7A24]] share the same front panel layout and operation. | ||
