WARNING: If the information about the time between trigger event and vertical
cursor 1 has to be accurate (error smaller than 10ns), it is necessary to make the
following correction: measure the time between the trigger event mark and the
real trigger event and use this value to correct the information.
If the sampling mode is activated, the icon is displayed with two rectangles
reflecting the amount of samples acquired (left rectangle represents channel A, right

red – less than 50% samples are acquired
yellow – more than 50% but less than 100% samples are acquired
green –100% samples are acquired
