This applies to the Memory function.
• To perform waveform X-Y synthesis, go to the Status screen, select the [Status] sheet, and set
[Format] to X-Y1 screen or X-Y4 screen. By assigning any analog channel to the X axis and Y
axis, up to 8 X-Y combo displays can be generated.
• Vertical axis (voltage axis) zoom also applies to X-Y synthesis.

X-Y Single The waveforms of graphs 1 - 8 are shown and
recorded on a single screen.
X-Y Quad
The waveforms of graphs 1 - 8 are shown and
recorded on a quadruplet screens.
Dots Measurement data only are shown as dots.
Order stored in memory will no longer be
known.
Line
Measurement data are linked by a line in the
order stored in memory and shown as a wave-
form. (default setting)
Whole
Wave
All data are used for X-Y synthesis.
A-B Wave
Only data range marked by A/B cursors is used
for X-Y synthesis.
• When [Dots] is selected for the Dot-Line inter-
polation setting, the waveform will be displayed
faster.
• Specify a range using the A/B cursors. (Memory
Function only)

Set the waveform color in the graph display.
Select
Move the flashing cursor to the graph color item to set,
and click it.
Set the waveform display color.
You can also select the same color as for another channel.

Select the channels for X-Y synthesis.
Move the flashing cursor to the items for the X (time
axis) and Y (voltage axis) and assign a channel.
The same channel can also be assigned multiple times.
Off Waveform display is off. If [Save Channel] is
set to [Disp Ch] in the Auto Save settings, the
data will not be saved.
See: "Select the channels to save." (p. 104)

The waveform is displayed. Set the display col-
or by clicking [] or [].

Synthesis for A/B section of a waveform
Perform the following steps.
1. Right-click and select [STATUS] to bring up the Status screen, and select
the [Status] sheet.
2. Select 1, 2, 4, 8 or 16 screens as [Format].
3. Right-click and select [DISP] to display the waveform.
4. Use the A/B cursors to specify the range for synthesis. See the following
pages. (p.120), (p.124)
5. Right-click and select [STATUS] to bring up the Status screen, and select
the [Status] sheet.
6. Select [X-Y Single] or [X-Y Quad] for [Format].
To move pen on synthesized waveform
You can move the pen over the entire waveform by rotating the mouse wheel
button.(Click the [WAVE] icon while AB CSR is displayed.)
The time at the pen position is shown at the top right of the screen.

This applies to the Memory function and Recorder function. (However, with the
Recorder function, waveform magnification is not available.)
Data details can be observed by magnifying the waveform along the horizontal axis (time axis).
Also, by compressing the time axis, overall waveform fluctuations can be readily seen.
On-screen magnification and compression is based on the left edge of the screen. However, when
A/B cursor appears on the screen, use the cursor as the standard to expand or compress.
The amount of magnification/compression can be changed after measurement.

When a waveform loaded from media is displayed at a high compression ratio,
the display may be slow to update.
