In the case of identifier 3 for iOLM, you can set a predefined list of
two or four items to use for each section of the measurement. The
items must be separated by a semi-colon (for example, “RX;TX”).
If you are using four items, they must all be different, or inverted
pairs (“AA;BB;CC;DD” or “AA;BB;BB;AA”). Depending on your
sequence for identifier 3, the output in the Overview page will
change.
Once you are done, click Next to proceed to the next step.
