The Tektronix 11A34 is a four-channel vertical amplifier plug-in for 11000-series and DSA600-series scopes. The attenuator modules each contain an M474 buffer amplifier. The main amplifiers in the 11A34 are four M377 chips. It contains two ACVS sample and hold modules.

Option 23 added four P6134 probes.

There is also a later version, the 11A34V introduced in 1991, for video applications. Development of the 11A34V was managed by Murlan Kaufman. (See also 11T5H.) more Information needed

The 11A34 uses the same firmware as the 11A32.
