Template:Plugin Sidebar 2 The Tektronix Type 3A1 is a dual-trace amplifier plug-in introduced in 1962 for 560-series scopes.

Specifications

Key Specifications

Bandwidth	10 MHz
Risetime	35 ns
Input impedance	is 1 MΩ // 47 pF
Deflection factor	10 mV/div to 10 V/div

Internals

The input signal passes through compensated attenuators and then into a cathode-follower stage made of two 7586 Nuvistor tubes.

Channel switching in ALTERNATE mode is done using diodes. The output stage that drives the vertical deflection plates of the scope uses a pair of 8233 frame grid power pentode tubes.
