Record lengths
Standard model:
1.25 k points, 12.5 k points, 125 k points, 1.25 M points, 6.25 M points (single
only), 12.5 M points (interleave and single only)
/M1(S) option:
1.25 k points, 12.5 k points, 125 k points, 1.25 M points, 6.25 M points, 25 M
points (single only), 62.5 M points (interleave and single only)
/M2 option:
1.25 k points, 12.5 k points, 125 k points, 1.25 M points, 12.5 M points, 62.5
M points (single only), 125 M points (interleave and single only)
/M3 option:
1.25 k points, 12.5 k points, 125 k points, 1.25 M points, 25 M points, 125 M
points (single only), 250 M points (interleave and single only)
History feature
Automatically saves history waveforms (past waveforms that have been acquired using the same
acquisition conditions).
Cannot be used in average mode, repetitive 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 2500 acquisitions (when the record length is set to 1.25 k points)
/M1(S) option:
Up to 10000 acquisitions (when the record length is set to 1.25 k points)
/M2 option:
Up to 20000 acquisitions (when the record length is set to 1.25 k points)
/M3 option:
Up to 50000 acquisitions (when the record length is set to 1.25 k points)
Accumulation
Waveforms can be accumulated. Count mode and time mode are selectable. Accumulated
waveforms can be saved and loaded.
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 on searching, see “Waveform Searching” described later.
Vertical zoom
Zoom source waveform: CH1 to CH4
*
, MATH1, MATH2
*
Zoom position:
The center position to zoom in on on the zoom source waveform can be
specified. Selectable range: ±4 divisions
Zoom factor:
The selectable range is 1 to 10.
Time axis zoom
Zoom position:
The center position to zoom in on on the main waveform can be specified.
Selectable range: ±5 divisions
Zoom factor:
Can be set using the time scale magnification knob. Press the knob to
switch between Coarse and Fine. With the Coarse setting, values are set
in 1-2-5 steps. With the Fine setting, values are set in more detail. The
selectable range is from 2 or 2.5 to the magnification that corresponds to
2.5 points/10 divisions or 3.125 points/10 divisions. If the record length or
time axis is changed, the DLM2000 retains the zoom factor as much as
possible.
Auto scroll feature: Automatically moves the zoom position in the specified direction.
Display format
The display can be divided into 1, 2, 3, 4, or 6 areas (1, 2, or 3 areas on the DLM2022, DLM2032,
and DLM2052).
The display format can also be set to Auto, a setting that causes the DLM2000 to automatically
select the number of areas depending on the number of displayed waveforms.
The zoom windows can be divided into 1, 2, 3, 4, or 6 areas (1, 2, or 3 areas on the DLM2022,
DLM2032, and DLM2052) or can be set to follow the main window setting. 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
Sampled points can be displayed by using the dot display, sine interpolation display, linear
interpolation display, or pulse interpolation display.
Graticule
The graticule can be set to one the following four grid types: dot grid, line grid, frame, and crosshair.
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), and the brightness can be adjusted.
If the backlight is off, pressing any key turns on the backlight.
The brightness level can be adjusted in the range of 1 to 8 (eight levels).
X-Y display
Two X-Y waveforms, XY1 and XY2, can be displayed (only XY1 on the DLM2022, DLM2032, and
DLM2052).
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.
X-Trace:
CH1 to CH4
*
, MATH1, MATH2
*
Y-Trace:
CH1 to CH4
*
, MATH1, MATH2
*
Time range: –5 divisions to +5 divisions on the main screen
