Template:Plugin Sidebar 2 The Tektronix 3A1S is a vertical plug-in for the 561S.
Key Specifications
| Deflection | from 10 mV/Div to 10 V/Div (in a 561S) |
|---|---|
| Bandwidth | 25 MHz |
| Rise time | 14 ns |
| Input impedance | 1 MΩ // 47 pF |
Internals
The input signal passes through a compensated attenuator switch and then into a 7586 cathode-follower biased with 2 mA plate current.
The gain stages use a mix of transistors and output stage driving the deflection plates is a transistor/pentode cascode circuit with T-coil loading.
The 3A1S is built in traditional ceramic-strip construction.
