The Rigol has some software from the manufacturer but it’s utter crap. This Excel file is just using some modified VISA VBA examples from Keysight IIRC which interfaces with the PSU over ethernet. The same thing is much easier to do in Python, which I use when doing the output measurements in the sphere, since it’s simple to integrate the spectrometer executables. Everything just gets written in a CSV file like this:
Voltage;Current;Power;X;Y;Z;Y;x;y;Y;CCT;deltae;CRI;R9;
2,6191;0,0072;0,019;33,509278;31,382019;10,213829;31,382019;0,446165;0,417841;31,4;2959;10,911796;94,9;78,7;
2,6558;0,0173;0,046;70,160871;65,747864;21,881268;65,747864;0,444647;0,416680;65,7;2974;10,125240;95,4;80,6;

Where Y is the lux reading from the meter. This has to be converted to lumens of course, but that happens automatically when I paste the data into Excel.
