AXIS Y1 softkey
Select AXIS primary softkey to toggle active axis between the Y1 and Y2 axes (this
softkey is displayed only if Y2 axis is used). The active axis name is displayed on
the AXIS primary softkey.
For tangent or regression lines, the active line selected by LINE SELECT softkey is
independent for each axis.
MARKER/CURSOR softkey
Select MARKER/CURSOR primary softkey to display secondary softkeys for
performing analysis with marker and cursor.
• MARKER softkey
Select MARKER secondary softkey to toggle the marker on and off. Marker
status is displayed on MARKER secondary softkey. If on, marker is displayed in
the plotting area. If off, marker is not displayed.
For Y1 axis, marker is a circle (o). For Y2 axis, marker is an asterisk (*). Active
marker is highlighted for the axis that is selected by AXIS softkey.
The 4155B/4156B remembers the location of marker. That is, when marker is
turned off, then redisplayed, it appears at its previous location.
• MARKER MIN/MAX softkey
Select MARKER MIN/MAX secondary softkey to move the marker to the
maximum or minimum measurement point. If this softkey moves the marker to
the maximum point, pressing the softkey again moves it to the minimum point.
• INTERPOLATE softkey
Select INTERPOLATE secondary softkey to toggle the interpolation mode. If
interpolation mode is on, marker can move on line between adjacent
measurement points. If interpolation mode is off, marker can be positioned on
measurement points only (not between measurement points).
