Arrangement and method for calibrating temperature sensors

A calibration arrangement for temperature sensors comprising:

• a sealable and thermally isolated chamber;
• a socket mount comprising:
• a number of reference samples with each of the reference samples being in thermal contact with the socket mount;
• and
• a number of sample sockets for devices-under test (DUTs) with each sample socket being arranged in proximity to and associated to at least one of the reference samples;
• a circuit board configured to provide electrical connection to the sample sockets and the reference samples in the socket mount;
• and
• a thermal chuck in thermal contact with the socket mount and the circuit board,
• wherein the thermal chuck is configured to thermalize the socket mount and the circuit board to a temperature set point, and
• wherein the DUTs are the temperature sensors to be calibrated.
