The Tektronix 26G2 is a ramp generator plug-in for the 2600 series mainframes.

It generates ramps with duration ranging from 10 μs to 10 seconds. There are outputs with different combinations of amplitude and output impedance. The 10 V output has very low output impedance (due to negative feedback) and has current limiting circuit that limits it to about 33 mA.The 1 V output has an output impedance of 50 Ω, resistive.

The 26G2 uses a 155-0029-01 as the trigger circuit, and a 155-0028-00 miller integrator chip to generate the ramp. Discrete bipolar transistors are used for the output amplifiers.
