The Tektronix 26G2 is a ramp generator plug-in for the 2600 series mainframes. It generates ramps with duration ranging from 10 microseconds to 10 seconds. There are outputs with different combinations of amplitude and output impedance. The 10V output has very low output impedance (due to negative feedback) and has current limiting circuit that limits it to about 33mA. The 1V output has an output impedance of 50 ohms, 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.
