In my day you used a calibration block and hand drew the DAC curve on the instrument screen with a grease pencil. I suspect all that is in the instrument software now.

Hello Ubiquitous Guest,

Does your DAC not come with a transfer function (found in the datasheet)?

For reference and an example, here is a DAC transfer function. See page 21.
