Oscilloscopes

Capture & Display Zoom and Search Functions

Real time Filter with optimum noise reduction supports a wide range of frequencies (from 8 kHz to 200 MHz)

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.

Zooms into two 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 costs money, 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 screen ( shows the current location). Waveform Search Criteria Edge, edge (with conditions), state pattern, pulse width, state width, serial bus (only on models with the serial bus analysis option)
Searchingfor history waveforms: the History Search Function Criteria can be specified for extracting desired waveforms from up to 50,000 previously captured waveforms.
Searching for waveforms 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 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, compute amplitudes every screen using multiple waveforms, and display amplitudes as trends. You can also display histograms referencing the voltage or time axis using values from repeated automated measurement of waveform parameters.

Trend display of waveform parameters Histogram display using the time axis

Measures voltage/time differences automatically - 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& ΔV, Marker, Degree Cursor.	Simultaneous level and with the ΔT&ΔV cursor
Analyzes Frequency Spectrums - FFT Analysis - Up to 2 FFT analyses 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 of the frequency components of waveforms filtered for limited bandwidth, of frequency for changes in period of rotary objects, and other phenomena.

Keeps 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 as 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. A file can be enlarged to confirm the data.

Thumbnails of saved filesThumbnail can be viewed full-size

Has a GO/NO-GO function GO/NO-GO can be determined using trigger conditions, zone waveforms, measurement parameters, and other criteria. For NO-GO, actions can 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 abnormality 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 functions and operations on screen without having to consult the user's manual.

Additional Option License for DLM2000

This is a license product for adding applicable optional features on to DLM2000 series on your own.

It is necessary to update main unit firmware in advance to V3.00 and above* in order to apply this license.

This license is only valid for 4 ch models.



* Firmware version 3.70 or higher is required to apply -F7, -F8, -F9, -X1 licenses.

Serial analysis function options (/F1 to /F9)

- UART (RS232)/I²C/SPI/CAN/CAN FD/LIN/FlexRay/SENT -

Triggers for embedded systems and in-vehicle bus signals are supported along with decode display analysis (serial bus analysis option only on 4 ch models). Logic input can also be used for serial buses (excluding FlexRay, CAN, CAN FD and LIN).



Intelligent serial bus auto setup:Complicated trigger and decode settings such as bit rate and threshold level are automatically detected by DLM2000.

Simultaneous analyses of four different busses:Up to four busses can be analyzed simultaneously. Waveforms and analysis results from busses with different speeds can be displayed using 2 Zoom windows.
