A thermoelectric heat pump is used to maintain the temperature of an integrated circuit under test. Temperature sensors placed on two sides of the integrated circuit measure and generate signals indicative of the temperature at the two surfaces, and the average of the two measured temperatures is compared against a value of a preset temperature to change the temperature of the heat pump to stabilize the temperature of the integrated circuit to a desired value.
