Scaling Diagrams
The analyzer provides several alternative tools for setting the sweep range and customizing the
diagrams. Pick the method that is most convenient for you.
Setting the Sweep Range
The sweep range for all channels is displayed in the channel list across the bottom of the diagram area:
To change the sweep range, use one of the following methods:
Press the START CENTER or STOP SPAN keys in the CHANNEL keypad.
Right-click the start or stop value in the channel list and select Start, Stop, Center, Span from
the context menu.
Select Start, Stop, Center, Span from the Channel – Stimulus menu.
Use the marker functions (MARKER FUNCT key).
Reference Value and Position
The analyzer provides three parameters for changing the scale of the vertical (response) axis:
•
Changing the Reference Value or Reference Position shifts the trace in vertical direction and
adjusts the labels of the vertical axis. Reference Value also works for radial diagrams.
•
Changing the Scale/Div. modifies the value of the vertical or radial diagram divisions and thus
the entire range of response values displayed.
•
The Scale/Div. and the Reference Value is indicated in the scale section of the trace list.
To change one of the parameters use one of the following methods:
Press the SCALE key in the TRACE keypad.
Right-click the scale section in the trace list and select the parameters from the context menu.
Select the parameters from the Trace – Scale menu.
Use the marker functions (MARKER FUNCT key).
