The 7904A re-implements the vertical amplifier using Hypcon-packaged amplifier chips designed for the [[7104]], such as the [[155-0178-00]]. | The 7904A ([[:Category:Introduced in 1984 |introduced in 1984]]) re-implements the vertical amplifier using Hypcon-packaged amplifier chips designed for the [[7104]], such as the [[155-0178-00]]. | ||
The 7904 had an elaborate 5-decade built-in calibrator with variable rate that was dropped from the 7904A. The [[7000-series remote control connector|rear remote control connector]] unique to early 7000-series scopes was dropped as well. | The 7904 had an elaborate 5-decade built-in calibrator with variable rate that was dropped from the 7904A.
