On the XL2 decay time, what is the difference between 1.0 Sec and the SLOW settings? Usually SLOW refers to 1 Second, I can't tell the difference between the two settings. I would suggest a 5 or 10 sec option, It would help to capture feedback or other spectrum events.
the 1.0s and the SLOW entry have both the same functionality
The FAST and SLOW choices have been added as they are mentioned this way in some measurement instructions.
I hope this helps.
