The active cursor refers to the cursor list you create. You can create as many cursors as you want. When you create the cursor list on the front panel, cursor 0, is the first one in the list, cursor 1 is the second, etc.
Hmmm..I got it to display the cursor with the correct power value however it doesnt seem to want to go to the peak. It its at the default position. I can clearly see the marker Y value being updated with the correct value or level however the X value seems tojust sit there.
Small update on the status I managed to get the cursor to reflect its position on the analyzer however the plot or graph if you will doesn't reflect the analyzer. The way I have it set is that it will do a full span look for the highest peek center on that peek then reduce the span to get a more accurate power level reading. While the marker on labiew has the correct values the plot is not giving you an accurate scale.
