The Tektronix 11A32 is a 400 MHz dual-channel amplifier plug-in for 11000-series scopes. Each of the attenuator modules contains an M474 buffer amplifier. Each of the attenuator modules feeds an M377 amplifier IC. The output signals of the two M377s combine at the output of the 11A32. Only one M377 has its main output enabled at a time. The fine steps between the deflection ranges are calibrated in 1% increments.
The 11A32 uses the same firmware as the 11A34.
