5. Verify Calibration Using TCAT-100 in Pulsed Mode

To verify calibration coefficients obtained from the Calibration module:

1. Set up a test sample the same way as for a standard calibration run.
2. Launch the Pulsed Mode software and select the TCAT-100 as the output device.
3. Select to read back the thermocouple. This lets the software simultaneously display the thermocouple signal alongside the Thermoreflectance or Infrared measurement data.
4. Compare results: the calibrated IR camera results should closely overlap the thermocouple results. [diagram/image in source — not reproduced here: Figure 13, pulsed-mode operation on the Microsanj test sample; Figure 14, final calibrated measurement in Pulsed Imaging mode]

Note: The thermocouple used with the TCAT module has a response time of approximately 0.5 seconds, so it may be necessary to lengthen the time scale to view an accurate response.
