Capture and Display Zoom and Search Functions |

Real
time Filter with optimum noise reduction supports a wide range of
frequencies (from 8kHz to 200MHz). The DLM2000 series has two types
of filters, one processed at the input circuit and one based on MATH
functions. These filters are effective for rejecting unwanted
signals allowing observation of only the desired bandwidths.
Real Time Filters
Each channel has 14 low pass filters available from 8kHz to 200MHz
Waveforms of limited bandwidths are stored in internal memory.

Computed Digital Filters
The input waveform can be filtered using an IIR filter, which is a
MATH function. Filtered waveforms can be displayed at the same time
as the input waveform for comparison. You can select low pass or
high pass filters.

Zooms into different points - Waveform zoom and search functions
|
|
Zoom two locations
simultaneously. Because the DLM2000 series lets you set zoom
factors independently, you can display two zoomed waveforms
with different time axis scales at the same time.
Also, using the
Auto Scroll function, you can automatically scroll waveforms
captured in long memory and change the zoomed location.
With Auto Scroll
you can choose forward, backward, fast-forward, scroll
speed, and other control options. |

|
Large
capacity memory gives you a variety of Waveform Search Functions |
|
|
|
Two types of waveform searching
Normally, searching for data takes time, and long memory is useless
without functions for extracting desired data from a large capacity
memory. That's why the DLM2000 series does not simply offer long
memory, it also provides powerful waveform search functions.
Searching for data in a single screen: The Zoom Search function
This function searches captured waveforms in the long memory and
displays waveforms that meet the search criteria in the zoom area.
The locations of the found waveforms are marked on the screen.

location)

Waveform
Search Criteria
Edge, edge (with conditions), state pattern, pulse width,
state width, serial bus (only on models with serial bus
analysis option). |
|
|
Searching for
history waveforms: The History Search Function. Criteria
can be specified for extracting desired waveforms from up to
20,000 previously captured waveforms. |
 |
|
| |
|
|
|
Searching for waveforms in zones in zones created by moving
measured waveforms up/down/left/right.
|
|
Search for
waveforms that pass through/do not pass through a rectangular
zone placed on the screen |
|

|
Useful Functions -
Fastest and most capable analysis |
|
|
|
Display trends
of peak-to-peak or pulse width per cycle
Measure function and statistics
Twenty-eight waveform parameters are included such as:
maximum, minimum, peak-to-peak, pulse width, period,
frequency, rise/fall time, and duty ratio.
Automated
measurement can be performed using up to 20 of these waveform
parameters. Also, waveform parameters can be measured
repeatedly, and the statistical values displayed (mean,
maximum, minimum, standard deviation etc). |
 |
|
|
|
|
Trend and
histogram displays
Waveform parameters such as period, pulse width, and amplitude
can be measured repeatedly and displayed in graphs.
In a single screen
you can observe period-by-period fluctuations, complete
amplitudes every screen using multiple waveforms, and display
histograms referencing the voltage or time axis using values
from repeated automated measurement of waveform parameters.

Cursor Measurement -
Cursors can be placed on the displayed waveform from signal
data, and various measurement values at the intersection of
the cursor and waveform can be displayed.
There are six
types of cursor, ΔT, ΔV, ΔT and ΔV,
Marker, Degree Cursor.

Frequency Spectrums
FFT Analysis -
Up to two FFT analysis can be performed simultaneously. FFT
can be performed on computed waveforms in addition to the
actual waveforms on CH1 to CH4.
Analysis can be
performed on the frequency components of waveforms filtered
for limited bandwidth, on frequency for changes in period of
rotary objects, and other phenomena. |
 |
|
|
|
|
Keep
waveforms with one push
By pressing the SNAPSHOT key to the lower right of the
screen, you can freeze a white trace of the currently
displayed waveform on the screen.
You can press
the key repeatedly and conveniently leave traces for
comparing multiple waveforms.
Also, snapshot
data recorded on screen can be saved or loaded as files, and
can be recalled for use or reference waveforms when making
comparisons.
|
 |
|
|
Displays
stored files in thumbnail format
Thumbnails of waveform data, waveform image data, and
Wave-Zone files can be displayed.
The image and
file names are shown so that you can view screen image
contents while copying or deleting files.
In addition to
normal-sized screens, you can even save wide images that
have been zoomed along the time axis.

Has a
GO/NO-GO function
CO/NO-GO can be determined using trigger conditions, zone
waveforms, measurement parameters, and other criteria.
For NO-GO,
actions can be be carried out at the same time such as
sounding a buzzer, saving the current waveform, or sending
notification to a designated e-mail address.
Waveforms in
which an abnormally occurred can be saved for confirmation
and analysis of the phenomena at a later time.

Can check functions with graphical online help
You can view detailed graphical explanations of the
oscilloscope's functions by pressing the "?" key in the
lower left of the screen.
This lets you get help on the functions and operations on
the screen without having to consult the user's manual. |
