Applications

The Tektronix 7A26 is a dual-trace vertical amplifier plug-in designed for use in the Tektronix 7000-series modular oscilloscope mainframes, a platform Tektronix introduced in the late 1960s that became a standard in electronic test labs through the 1970s and 1980s. The 7A26 provides two independent vertical input channels with selectable coupling, sensitivity, and display modes, making it one of the most widely used plug-ins in the 7000 family. This instruction manual is the primary reference for technicians and engineers who operate, calibrate, or service the 7A26 — covering front-panel controls, internal adjustments, and full schematic diagrams. Today it remains sought after by labs and collectors maintaining vintage Tektronix 7000-series equipment, as original Tektronix documentation is essential for accurate calibration and repair work on these instruments.
