Part Number: REF3312
How do you measure the voltage reference output to produce a smooth plot of the output voltage vs temperature. There does not appear to be noise in the plot. I would like to reproduce the datasheet's output voltage vs temperature plot using my own measurements.
Output voltage vs temperature is a discrete graph made of many points. For example, we adjust the temperature from 25C to 27C and let the device soak for at least 5 minutes then take a temperature reading. We combine these readings into a graph. Noise is a time based measurement and will not apply in this type of graph because we aren't continuously sampling the output as we change temperature.

In reply to Marcoo Z:
Thanks for the response Marcoo. Is a single voltage measurement taken at each temperature, which would include the effect of noise on its magnitude, or is the effect of noise reduced by doing something like taking a large number of measurements at that temperature and calculating the average?
In reply to Tyler Archer:
Each point should be one measurement. The effect of noise is overall small compared to temp drift that it does not appear.
