The Status Operation Register bit 5 "Waiting for Trigger" is set at the same time as the Sweeping
or Measuring bit is set. It is cleared when the trigger actually occurs (that is, after the trigger
event occurs and all the applicable trigger criteria have been met). A corresponding pop-up
message ("Waiting for trigger") is generated if no trigger signal appears after approximately 2
sec. This message goes away when a trigger signal appears.
