Hi,

the numbers are the sampling clock numbers, you can change this with cursor "above" this bar, right mouse click and change from sample number to time units (a window will appear to enter the sampling clock).

For the trigger condition: If you set more than one trigger, than all conditions must be met and with the last condition being true the trigger activates. Best on trigger options is to look into the Help (search for trigger condition) as there are many options to choose from...

Best Regards
