Poor Men's SMU, part 3: Diodes are Forever
Posted on zo 17 januari 2021 in NLnet
This is third part on my adventures with the AD5522 SMU development board. For history you can look at part 1 and part 2.
After getting the SMU working and being able to operate it from Jupyter notebooks on a raspberry Pi I now decided to use the device to measure some diodes/LEDs. I did the measurement and the plotting again in a Python notebook. I also used the notebook to comment on the results. Head over to the html version of the notebook to learn all about the diode and LED results.
As indicated in the notebook, the SMU needs to be calibrated to be able to measure smaller values accurately. So that is what I am currently working on and (hopefully) you will here more about this in the near future.
