The Tektronix 7A29P is a programmable 1 GHz single-channel vertical plug-in for 7000-series scopes.
It is primarily intended for the 7912HB and the 7854 when paired with the 021-0374-00.
Key Specifications
| Bandwidth | 750 MHz (in 7912HB) |
|---|---|
| Input impedance | 50 Ω |
| Max. input | max. 5 VRMS or 25 V peak; max. 100 V additional DC component in AC mode |
| Deflection | 10 mV/div to 1 V/div, 1–2–5, ±2%; variable 2.5:1 (reduced bandwidth) |
| Channels | Single channel |
Internals
The 7A29P employs a number of Tek-made custom Hypcon-packaged hybrids initially designed for the 7A29 and the 7104, the 155-0180-00 fast input protection, 155-0181-00 input amplifier and 155-0175-00 trigger amplifier (2 ×). It also uses the 155-0076-00 input protection chip initially developed for the 485.
It uses a "feed-beside" scheme implemented with standard low-frequency operational amplifiers to compensate for low-frequency anomalies in the frequency response that are attributed to transistor heating.
The input connector is a special Tek-made part that is exactly 50 Ω. Typical BNC connectors are around 52 Ω.
