The '''Tektronix 7A19''' is a one-channel 600 MHz vertical amplifier plug-in for [[7000-series scopes]], introduced with the [[7904]] mainframe in 1971. | The '''Tektronix 7A19''' is a one-channel 600 MHz vertical amplifier plug-in for [[7000-series scopes]], designed by [[Thor Hallen]] and introduced along with the [[7904]] mainframe in late 1971/early 1972 (note 1). | ||
The 7A19 has no variable gain control. An option (#4) was available that added a variable signal delay (± 0.5 ns implemented using a mechanically variable passive delay line), intended to match timing between multiple channels. | The 7A19 has no variable gain control.
