The Tektronix 3A10 is a differential amplifier plug-in for 560-series scopes.

It is intended for use with transducers and for that purpose it has a DC-coupled differential input and a variable voltage supply for powering the transducer. It also has a 6-pin input connector (Bendix MS3101A-10-6S) to directly connect to the 015-0169-00 Strain Gage Adapter.

The 3A10 circuit is partially based on the 1A7A's.
