●
Select "Start", "Stop", "Center", "Span" from the "Channel Stimulus" menu.
●
Use the marker functions (MARKER FUNCT key of the hardkey bar).
2.3.2.2
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 divi-
sions 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 of the hardkey bar.
●
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 of the hardkey bar).
2.3.2.3
Autoscale
The "Autoscale" function adjusts the scale divisions and the reference value so that the
entire trace fits into the diagram area. To access "Autoscale", use one of the following
methods:
●
Press the SCALE key in the TRACE keypad of the hardkey bar.
●
Right-click the scale section in the trace list and select "Autoscale" from the context
menu.
●
Select "Autoscale" from the "Trace
–
Scale" menu.
2.3.2.4
Circular Diagrams
The radial scale of a circular ("Polar", "Smith" or "Inverted Smith") diagram can be
changed with a single linear parameter, the "Reference Value". The reference value
defines the radius of the outer circumference.
●
Increasing the "Reference Value" scales down the polar diagram.
●
Decreasing the "Reference Value" magnifies the polar diagram.
The "Reference Value" is indicated in the scale section of the trace list.
