ZA 57630
In the single display style, the vertical axis on the left side is called the Y1-axis and the
vertical axis on the right side is called the Y2-axis. In the split display style, the vertical axis
of the upper graph is called the Y1-axis, the vertical axis of the lower graph is called the
Y2-axis, and the X-axis is common for both graphs.
■ Data display types
The measurement data that is displayed on graphs is measurement data (MEAS) and up to
eight reference data (REF1 to REF8). The results of sweep measurement is always MEAS. As
sweep measurement is performed, MEAS is updated successively. REF1 to REF8 can be
updated by copying MEAS.
Each of MEAS and REF1 to REF8 can be set to be displayed or hidden on the graphs.
■ Markers
There are markers for reading the X, Y1, and Y2 values of data traces on graphs. There are
up to eight markers (MARKER1 to MARKER8), and MARKER1 can be used be used as the
normal marker and MARKER2 to MARKER8 can be used as normal markers,
⊿
markers, or
⊿
TRKG markers. A
⊿
marker is a marker to read the information of the X, Y1, and Y2 axis
difference information relative to MARKER1. The display of a
⊿
TRKG marker is the same
as that of a
⊿
marker, but the marker is moved to keep the X-axis interval constant if
MARKER1 is moved.
One of the eight displayed markers becomes the active marker, and the position of the active
marker can be moved by knob operation and its read values are displayed in the marker
display area above the graph. The active marker can be selected with
ACTIVE
or
[ACTIVE]
.
A normal marker is displayed as “*,” a
⊿
marker is displayed as “
⊿
,” and a
⊿
TRKG marker
is displayed as “T” on the graph. The marker numbers (1 to 8) are displayed as numerical
values directly above the markers. The marker displayed enclosed in a frame is the current
active marker.
The data that is reference by the markers can be set to the measurement data (MEAS) and
reference data (REF1 to REF8) by using the
TRACE
key or
[TRACE]
button.
