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 CH8, Math1 to Math4
Zoom position: The center position to zoom in on on the zoom source waveform can be specified.
Selectable range: ±4 div
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 div
Zoom factor: Can be set using the time scale magnification (ZOOM) knob. Press the ZOOM knob
to switch between a mode in which you can set values in 1-2-5 steps or a mode
in which you can set values in detail (FINE). 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 DLM4000 retains the zoom factor as
much as possible.
Auto scroll feature: Automatically moves the zoom position in the specified direction.
Display format
Auto or 1, 2, 3, 4, 6, or 8 areas.
When set to Auto, the DLM4000 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, 6, or 8 areas 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
Interpolation between sampled points can be set to sine interpolation, linear interpolation, pulse
interpolation, or no interpolation.
Grid
The grid in the window can be set to 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 Waveform labels and scale values can be turned on and off. Waveform labels are assigned
separately to channels.
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.
If the backlight is off, operating any key or knob turns on the backlight.
The brightness level can be adjusted in the range of 1 to 10 (10 levels).
X-Y display
Four X-Y waveforms, XY1 to XY4, can be displayed.
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.
XY1, XY2
X-Trace: CH1 to CH4, Math1, Math2
Y-Trace: CH1 to CH4, Math1, Math2
XY3, XY4
X-Trace: CH5 to CH8, Math3, Math4
Y-Trace: CH5 to CH8, Math3, Math4
Display range: –5div to +5div on the VT waveform display
Accumulate
Accumulates waveforms with gradually decreasing intensity for the specified amount of time.
The accumulation time can be set to a value from 100 ms to 100 s or to infinite.
Intensity and color modes can be selected.
Intensity: Accumulates waveforms using separate channel colors with gradually decreasing
intensity.
Color: Displays the intensity that appears in intensity mode using different colors
Snapshot
The currently displayed waveforms can be retained on the screen.
Snapshot waveforms can be saved and loaded.
Clear trace
Clears all displayed waveforms.
