7A29

Template:Plugin Sidebar 2 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.

The 7A29 uses a special Tek-made BNC connector that is exactly 50 ohms. Typical BNC connectors are around 52 ohms.

There is also a 7A29P, which has digitally programmable gain, intended for the 7000 series digitizers.
