History
Automatically saves history waveforms (past waveforms that have been acquired using the same
acquisition conditions).
Cannot be used in average mode, repetitive sampling mode, or roll mode. Cannot be used at
record lengths that only allow single trigger mode.
The maximum number of acquisitions that can be held is as follows:
Standard model:
Up to 20000 acquisitions (when the record length is set to
1.25 k points)
Models with the /M1 option: Up to 50000 acquisitions (when the record length is set to
1.25 k points)
Models with the /M2 option: Up to 100000 acquisitions (when the record length is set to
1.25 k points)
Zoom
Expands waveforms vertically (analog waveforms only) and horizontally (along the time axis).
Two locations, Zoom1 and Zoom2, can be expanded. Separate magnification settings can be
specified for each location.
Auto scrolling and searching are available as supplementary features of the zoom feature. For
details, see “Computation, Analysis, and Searching” in section 6.5, “Features.”

Zoom position:
The center position to zoom in on on the zoom source waveform can
be specified. Selectable range: ±4 div
Zoom factor:
Selectable range: 1 to 10
Time axis zoom
Zoom position:
The center position to zoom on the main waveform can be specified.
Selectable range: ±5 div
Zoom factor:
Can be set using the time scale magnification knob. Press the knob
to switch between Coarse and Fine. When set to Coarse, the value
can be set in 1-2-5 steps. When set to Fine, the value can be set
more finely. The selectable range is from 2 or 2.5 to the magnification
that corresponds to 2.5 points/10 div or 3.125 points/10 div. If the
record length or time axis is changed, the instrument retains the
zoom factor as much as possible.
Auto scroll feature: Automatically moves the zoom position in the specified direction.
Display format
1, 2, 3, 4, 6, 8 divided windows (1, 2, 3, 4 divided windows on the DLM3022, DLM3032, DLM3052)
are available.
The number of divisions can be set to auto. When set to auto, the number of divisions is selected
automatically according to the number of displayed traces.
The zoom window can be synchronized to the main window or set to 1, 2, 3, 4, 6, 8 divided
windows (1, 2, 3, 4 divided windows on the DLM3022, DLM3032, DLM3052). When a zoom window
and the main window are displayed at the same time, you can set the vertical display area of the
main window to 20% or 50%.
Display interpolation
Select dot display of sample points, sine interpolation display, linear interpolation display, or pulse
interpolation display.
Graticule
Dot grid, line grid, frame, and crosshair are available.
Further, the fine grid can be turned on and off.
The normal grid appears in front of the waveforms, and the fine grid appears in the back of the
waveforms.
Auxiliary display on and off Scale values and waveform labels can be turned on and off.
LCD backlight adjustment
The LCD backlight can be turned off manually or automatically (automatically turns off when a
specified time elapses with no key activity). The brightness can be adjusted.
When the backlight turns off, pressing any key will turn it back on.
The brightness can be adjusted between level 1 and 10 (10 levels).
X-Y display
Two X-Y waveforms, XY1 and XY2, can be displayed (XY1 only on the DLM3022, DLM3032, and
DLM3052).
X-Y waveforms are displayed in their dedicated window and can be displayed simultaneously with
T-Y waveforms.
Specify the X-Trace, Y-Trace, and the X-Y display time range.
