OPT3101-SDK: Questions about calibration SDK step INLAB_STEP_2 and INLAB_STEP_3

Part Number: OPT3101-SDK


Hello TI

I have some questions about temperature crosstalk compensation and temperature phase offset compensation.

I have carried out the process following the guidelines in the SDK manual
When I calculate my coefficients and enter them in the OPT3101Coefficients.cpp file for post temperature crosstalk compensation I launch the TESTING_LIVE_VIEW mode it seems that the previous INLAB_STEP_1 calibration is no longer stable and the distances change.

My questions regarding these:
1 - What are the ranges for the compensation coefficients to know if my results are correct.

2 - When INLAB_STEP_3 is performed for phase compensation, the distances must be the same as in step INLAB_STEP_1 or others must be used because with the compensation performed in step INLAB_STEP_2 the amplitudes are now different.

3 - A distance must be chosen that gives us an amplitude in the range of 16000 to 24000. The question here is to choose, for example, 21000 and choose the distance for each channel that has that amplitude.

4 - Is it a bad idea to perform the INLAB_STEP_1 calibration and the rest of the steps inside the temperature chamber?

5 - It is necessary to have some resolution for data collection, that is, when the temperature chamber is cooling, control it so that it is lowered every 2 °C, or it is enough to place the temperature chamber, for example, at 70 °C and leave it. do the data collection like the SDK does.
