General steps for adding a marker
Take adding Marker 1 for example:
Using Pass/Fail Limit Lines
Limit lines will alert the user to a measurement that
exceeds the upper limit value of a trace. Limits are set in
dB, and define the location of the limit lines displayed on
the screen.
The tester applies upper limits only. Limit lines are used
as pass/fail indicators:
• If the amplitude of a measured trace is below the limit
line, a green Pass indicator is displayed in the upper
right corner of the screen.
• If the amplitude of a trace is above a limit line, a red
Fail indicator is displayed in the upper right corner of
the screen. A limit fail beep sound can be turned on
for an additional trace fail indicator.
Two types of limit lines
• Single limit 
A single limit value is applied over the full frequency
range, 25 MHz to 4 GHz. A maximum of two single
limit lines may be applied.
