If you get the "Sorry, the file cannot be displayed. There seems to be a technical issue ..." error when trying to view an image, a workaround is to click on the cog icon in the upper right side of the media viewer, and then select "Disable Media Viewer". We are aware of the problem and are looking for a solution.

26G2

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 a current limiting circuit that limits it to about 33 mA. The 1 V output has a resistive output impedance of 50 Ω.

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