Yokogawa DLM2000 MSO Series 200MHz-500MHz Oscilloscopes

Product Overview:

  • Bench-top oscilloscope for electronic design or debug.
  • Ergonomic and easy to use, and packed with features
  • Bandwidths from 200 to 500 MHz and memory from up to 250 Mpoints, you can be certain there is a DLM2000 to meet your application and budget
  • With the DLM2000's industry first “flexible MSO input”, you can choose to activate channel four as an analog input, or use it to acquire 8 bits of logic instead
  • Modern electronics include analog and digital circuitry—and the DLM2000’s flexible MSO input lets you measure both, including mixed signal triggers and decoding of parallel or serial bit patterns.


Compact & intuitive operation

Easy-to-Use & Easy-to-See

Easy to use. Portrait body + large screen makes display easy to see.

We elevated the large (8.4-inch) LCD screen up into the line of sight. Also, the portrait format saves space on the desk or test bench. A compact "personal oscilloscope" designed for easy viewing and ease of use.

Signal Observation on 4 channels or more...

Switch between analog and logic channels

Flexible MSO input

Four channels is not sufficient to view the functioning of digital control circuits. The DLM2000 series converts 4 ch of analog input to 8-bit logic, and functions as a 3 ch analog + 8-bit logic MSO (mixed signal oscilloscope).

Large capacity memory up to 250 Mpoints

Long memory is necessary to keep high speed sample rate in long term measurement.

<Basic Formula> Measuring time = Memory length/Sample rate

If 250 Mpoints (Memory expansion option /M3) is installed, Max. 0.2 sec waveform can be captured even at 1.25 GS/s sample rate when taking 2 ch measurements in Single mode.

Large Capacity Memory

History function - Automatically save previously captured waveform

 With the DLM2000 series, up to 50000 previously captured waveforms can be saved in the acquisition memory. With theDLM2000 History 1 History function, you can display just one or all of the previously captured waveforms (history waveforms) on screen. You can also perform cursor measurement, computation, and other operations on history waveforms. Using the History function, you can analyze rarely-occurring abnormal signals.

DLM2000 History Function

Trigger function capturing combined analog/digital waveforms

The DLM2000 series comes with a variety of easy-to-configure triggers combining analog and logic inputs such as edge, enhanced, and B triggers.

DLM2000 Trigger Function

Trigger Function Example

A to B(n) Trigger:

Trigger on the 7th edge of signal on B. This is effective for measurements with shifted timing, such as non-standard video signal vertical/horizontal periods or motor reference position pulses and drive pulses.
DLM2000 Trigger Function 2
Serial Pattern Trigger (user defined):

Trigger on an arbitrarily set pattern of up to 128 bits. This is effective for detecting ID/Data and other portions of proprietary communication formats.
 DLM2000 Trigger Function 3
Dual Bus Trigger: 

Trigger on a combination of CAN and LIN bus triggers. I2C + SPI bus triggers, and other combinations are possible.

Trigger when either LIN or CAN bus signal conditions become true.

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.

Real Time Filters 

Each channel has 14 low pass filters available from 8 kHz to 200 MHz. Waveforms of limited bandwidths are stored in internal memory.    

DLM2000 Real Time Filter 1 3

Cutoff Frequencies:   

200 MHz, 100 MHz, 20 MHz, 10 MHz, 5 MHz,

2 MHz, 1 MHz, 500 kHz, 250 kHz, 125 kHz,

62.5 kHz, 32 kHz, 16 kHz, and 8 kHz

Processing with built-in filters

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.DLM2000 Digital Filter 1 2

Cutoff Frequency Setting Range: 0.01 Hz to 500 MHz

Filtering of a PWM waveform using computation

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.
 BU DLM2000 3

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).

DLM2000 Zoom Search 1Waveform Search Criteria 

Edge, edge (with conditions), state pattern, pulse width, state width, serial bus (only on models with the serial bus

analysis option)
Searching for history waveforms: the History Search Function

Criteria can be specified for extracting desired waveforms from up to 50,000 previously captured waveforms.
DLM2000 History Search 2
DLM2000 History Search 3

Searching for waveforms in zones created by moving measured waveforms up/down/left/right. 
History Search Function 4

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.).

DLM2000 Function 1
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. 
DLM2000 Function 2

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.

DLM2000 Function 3

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.

DLM2000 Function 4

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.                                                     
 DLM2000 Function 5
 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.
 DLM2000 Function 6 1

Thumbnails of saved files      Thumbnail 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.

 DLM2000 Function 7
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.
