To set the sweep range use one of the following methods:
Define Start and Stop values
1. Create two normal markers, e.g. the markers Mkr 1 and Mkr 2, and place them to the desired
start and stop values of the sweep range.
2. Activate Mkr 1 and click Trace – Marker Funct. – Start = Marker .
3. Activate Mkr 2 and click Trace – Marker Funct. – Stop = Marker .
Use a definite Span
1. Create a marker and set it to delta mode.
The analyzer automatically creates a reference marker in addition to the delta marker.
2. Place the reference marker to the desired start value of the sweep range.
3. Set the value of the delta marker equal to the desired (positive or negative) span.
4. Activate the delta marker and click Trace – Marker Funct. – Span = Marker .
To move the trace relative to the vertical axis proceed as follows:
1. Create a normal marker, e.g. the marker Mkr 1, and place it to a particular trace point. E.g. you
can use the marker Search functions to locate a maximum or minimum on the trace.
2. Click Trace – Marker Funct. – Max = Marker to move the trace towards the upper diagram
edge, leaving the values of the vertical divisions (Scale Div.) and the overall vertical scale
unchanged. Analogously, click Min = Marker to move the trace towards the lower diagram
edge, or click Ref Value = Marker to move the trace towards the Reference Value.
Enlarging the Diagram Area
The analyzer provides different tools for customizing the contents and size of the diagram areas:
•
Maximize allows you to enlarge the active diagram area to occupy the whole window. A double-
click on any point in the diagram area is equivalent to the Maximize function.
•
The Title, the Softkey Labels, the Status Bar and the Front Panel Keys are optional display
elements which you can hide in order to gain space for the diagram.
Use the context menu of the diagram area, the keys in the DISPLAY keypad or the Display
menu to access the scaling functions above.
