1.19.2.4 Marker Type
Marker type pop up menu appears, these include Value, Max and Min marker types. Refer to Figure 20
1.19.2.4.1 Value Marker
Value markers allow you to enter an absolute X value, once an absolute marker value has been entered, this can be
further adjusted by the slider control or entering a new value.
1.19.2.4.2 Max Marker
When both max and min Marker types have been selected it is possible to enter a threshold value. The Max marker will
ignore maxima below the threshold value.
1.19.2.4.3 Min Marker
When both max and min Marker types have been selected it is possible to enter a threshold value. The Min marker will
ignore minima above the threshold value.
1.19.2.4.4 LocalMax
Local max markers are initially located at the first peak after the trigger point, or at the X axis point if provided. Localmax
markers can be locally adjusted by the move control. See
1.19.2.4.5 LocalMin
Local max markers are initially located at the first null after the trigger point, or at the X axis point if provided. Localmin
markers can be locally adjusted by the move control. See
1.19.2.4.6 Absolute
Absolute markers are able to be set to an arbitrary point on the trace graticule, Both (X Value and Y Value) can be
entered.
1.19.2.5 Marker reference menu
This marker pop-up menu allows the user to select what point the marker result is referenced to. In its simplest form
Origin, is the origin of the trace (0,0), this gives you absolute marker values. In addition to this on the pop-up menu,
any other currently set marker on any other trace can be compared as a result shown on your current marker result.
TrX signifies the trace number. Tr1-X Indicates the marker number on that trace. So to do a Delta measurement from
Tr1-1 (Trace 1 Marker 1) Marker 2, the delta result would have it’s reference set to Tr1-1 , Marker 2 will then show the
difference in frequency and level from marker 1 on trace 1 .
1.19.2.6 Marker Focus/Marker menu
A Short press toggles focus between markers on the current trace, if a marker has focus it can be edited directly in the
marker menu, the Marker Scroll Bar functions will also be attached to it, if it has focus.
1.19.2.7 Marker Scroll Bar
If the marker that has focus is an adjustable type (Localmax, Localmin, Value) you can slide up and down on the move
scroll bar to move/adjust the marker position.
1.19.2.8 Trace Hold
A Short Press toggles between max hold off and max hold on . Likewise if Min Hold is set will toggle between min
