Move Markers Left or Right
- press the left and right navigator keys to scroll the selected marker. Auto
speed-up is provided. Alternatively press the screen at the point that you want the selected marker to
move to.
Find next Peak
- press the up or down navigator keys to move the selected marker to the next higher or
next lower amplitude peak.
Note: This function is peak tracking and will therefore follow the peak if the frequency is changing. To
cancel peak tracking press the left or right navigator keys once.
Turn Markers Off

first).

Note:
Markers maintain a fixed position on the screen. Changing any sweep parameter (Start, Stop,
Centre, Span) will change the frequency at the marker position. The exception to this is the C = M1
function which also repositions the marker at the new centre frequency, see section 19.4.
