Using Markers
Markers are quick and easy ways to take precise measurements.
To place markers:
1. Make sure that the sampling is running.
2. Right-click on the sample screen, then select Marker 1.
3. Click on the location where you want to put the marker.
4. Repeat steps 2 and 3 for the other marker.
Note: You can also select the markers from the Display menu.
The figure below shows an example where we have placed two markers in
a 160 Gb/s pattern to measure the spacing between two slopes. The
difference in time and power is shown at the top right corner of the sample
screen. The red and blue indicators will give you the power and time
values for each marker.
