-The '''Tektronix 7A29''' is a 1 GHz single-channel vertical plug-in for [[7000-series scopes]].  It is primarily intended for the [[7103]] and [[7104]].  It uses a "feed-beside" scheme to compensate for low-frequency anomalies in the frequency response that are attributed to transistor heating.

+Like the [[7A19]], it has no variable gain control, but a variable signal delay was available as an option.
-The 7A29 uses a special Tek-made BNC connector that is exactly 50 ohms.  Typical BNC connectors are around 52 ohms.
