4.5.9 Temperature Variation Accuracy Measurements

Objective: record the accuracy of reference design, place reference design in a temperature-controlled chamber, change temperature to -20°C, wait for an hour, and record error measurements. Repeat the same process for temperature 50°C and record error measurements.
