Yokogawa's new DLM6000 series digital and mixed signal oscilloscopes boast fresh physical and on-screen interfaces, based on extensive market research and user feedback. It incorporates dedicated, backlit buttons for the most commonly accessed settings, and unique Yokogawa controls, like the 5-way selector button and spring loaded ‘jog shuttle' control.

The DLM6000 series oscilloscopes offer an extensive range of capabilities for waveform characterization, powerful tools for detecting glitches and anomalies, advanced signal enhancement and noise reduction technologies, and a range of options for serial bus analysis and power measurement. Select from models with four channels plus 16 or 32 bit logic inputs, and 500MHz, 1.0GHz, or 1.5GHz bandwidths.

High-Speed Acquisition and History Memory

High Acquisition Rate Unchanged Even When Displaying Logic Signals
  • During continuous measurement : Up to 25,000 times per second per channel
  • In N Single mode : Up to 2.5 million times per second per channel

Waveform update rate determines your probability of catching an intermittent glitch.  On other mixed signal oscilloscopes, enabling the logic inputs severly impacts waveform update rate.  The DLM6000 maintains waveform update rates  so you can detect abnormalities and transients in your analog or logic channels.

History Memory Function and
High Speed Acquisition
  • Preserve up to 2000 captures of actual waveform data (not screen images)
  • After measurement has stopped, you can review past waveforms individually for detailed analysis.
  • Search and Zoom
  • Automated measurement of waveform parameters
  • Variety of computations

High-speed acquisition means you can even capture instantly

On most oscilloscopes, to observe and analyze abnormalities such as unpredictable noise in detail, you have to devise clever trigger settings and re-measure the event.
But with the DL6000/DLM6000 there is no need to re-measure the phenomena because once the event occurs, you can use the History Memory function to recall past waveforms that were originally displayed on screen.

DLM6000 Web 13




Example of the usefulness of observing intermittent signals: Observation of SD bus commands

SD card bus commands are sent intermittently, and the non-signal portions of these waveforms do not need to be analyzed.

To be able to capture the commands that you want to observe from such signals, you can set a serial bus trigger and use the History memory to acquire up to 2000 of the waveforms that match the trigger conditions into History memory while ignoring the non-signal waveforms.

Rather than acquiring a single waveform to the entire acquisition memory, you can acquire multiple waveforms of only the needed command, and analyze them.

Search & Zoom



DLM6000 Web 15 Quickly extract locations and abnormalities you wish to analyze from the acquired waveform data, and zoom in anywhere on waveform details.
The DL6000/DLM6000 series has enhanced Search and Zoom functions for searching for desired portions of waveform data and observing those waveforms in detail.


Search function for extracting abnormal phenomena
The search function can search both analog and logic signals in History Memory (History Search).

Main Search Functions:

  • State search (Hi/Lo setting of each channel)
  • Serial pattern (I2C, SPI, CAN, general-use pattern) search
  • Polygon zone search
  • Waveform zone search
  • Parameter search (Measured parameters, FFT, etc.)

Display two zoom areas simultaneously

Because the DL6000/DLM6000 series lets you set zoom factors independently, you can display two zoomed
waveform areas with different time axis scales at the same time.

Zoom and scroll with the zoom knob and jog shuttle
Intuitively adjust the zoom factor with the zoom knob, and the scroll with the jog shuttle. You can also scroll the zoom window automatically with the Auto Scroll function.

Automated measurement of waveform parameters

Automated measurement of waveform parameters - Automatically display waveform values

  • Vertical waveform parameters such as amplitude, RMS
  • Time axis waveform parameters such as frequency, startup time
  • Delay time between specified signal edges
  • Automatic measurement of time axis waveform parameters is even possible on logic signals
  • Measurement Location Indicator indicates the measured location of a specified item
  • Display the statistics on the automated measurement values of waveform parameters.
  • Normal statistical processing (Continuous)
  • Statistical processing for each period (Cycle)
  • Statistical processing of history waveforms (History)

Measure a variety of parameters automatically
Simply select the check boxes of parameters you wish to measure automatically in the setting screen's parameter list.

Simultaneously measure up to 16 parameters during acquisition. Additional measured values can be obtained in the analysis screen, or via PC communication.DLM6000 Web 17

You can measure waveform parameters of every cycle of a periodic waveform, and display results in lists and trend graphs. This is useful when evaluating period-by-period waveform fluctuations or loss in switching circuits. DLM6000 Web 18


Real Time Filter and High Resolution Mode

Input Filters

The DLM6000/DL6000 can restrict filter out unwanted high frequency noise and expose only the frequency bandwidth of the signals you are working with.  Every analog channel offers independent, real-time bandwidth filters.



  • Analog Filters: 200MHz / 20MHz
  • Real-time Digital Filters: 8MHz / 4MHz / 2MHz / 1MHz 500kHz / 250kHz / 125kHz / 62.5kHz / 32kHz/ 16kHz / 8kHz

DLM6000 Web 6 1




High Resolution Mode

Digital oscilloscopes have offer excellent time resolution.  However, nearly all digital oscilloscopes provide only 8-bits of vertical (voltage) resolution.  With Yokogawa's High Resolution mode (real-time FIR filter), the oscilloscope will oversample and reconstruct a higher resolution signal with resolutions of up to 12 bits.  Unlike averaging, High Resolution mode does not require a repetitive signal and works on single shot acquisitions.






Switching Waveform Measurement
When measuring SMPS waveforms, highly precise evaluation is impossible due to the insufficient dynamic range offered by 8-bit oscilloscopes. In such cases, you can use High Resolution mode to raise the precision of the waveform as well as of any computed results.

Logic signal measurement and analysis

Observing up to 32-bit logic signals together with analog signals

Observing many signals simultaneously and checking their correlations and timing is an effective means of verifying increasingly complex embedded systems.

With the DLM6000 series, you can measure up to 32-bit logic signals and 4 channels of analog waveforms simultaneously, and investigate hidden data in waveforms using bus analysis and computation functions.

DLM6000 Web 19 1
Grouping logic signals to make them easy to read and understand

As many as 5 groups of logic signals can be defined. You can enter display settings for each group, and specify which bit in each group is the LSB or MSB
regardless of the bit arrangement of the logic probe.
This means that even if pin assignments or signal arrangements change, you only need to change settings rather than to repeat the probing of the circuit.

DLM6000 Web 32


Bus and State displays make logic signals easy to read and analyze


The DL6000/DLM6000 is not limited to displaying logic signals as waveforms. It can also show logic signals assigned to groups in a Bus display, or specified
clock signals in a State display.
Therefore, parallel output values of an address bus or A/D converter can be read directly. Functions like these make analysis of logic signals easy, so that operating checks of the device under test can be performed more quickly and accurately.

Virtual D/A Computation function displays to 32-bit logic signals as analog waveforms

The DL6000/DLM6000 includes a Virtual D/A Computation function, in which address bus signals or logic signals from data converter I/O can be converted to analog waveforms and displayed. You can display logic signals output from an A/D converter, and by comparing them with the original analog waveforms prior to conversion, you can investigate the general dynamic characteristics of the A/D conversion. Displaying the address bus signal as a waveform is also useful for identifying instances of abnormal memory access. D/A converted waveforms can undergo FFT analysis or have additional digital filtering computations applied to them.

Making logic signal measurement probing easier and minimizing effects on the target

There are two different types of logic probe that can be used with the DLM6000, depending on the application.



  • 250 MHz logic probe (model 701989, Input Impedance: 100 kΩ)
  • The model 701989 is a 250 MHz logic probe with a tip shape designed for probing circuit boards. In addition to probing with the pincher tip, the tips can be stacked in the included holder, making it easy to connect to and disconnect from a 2.54 mm pitch box connector.




  • High impedance logic probe (model 701988, Input Impedance: 1MΩ, Max. toggle speed 100MHz)
  • The model 701988 is a 100 MHz general-purpose logic probe with an impedance of 1 MΩ. Its high impedance gives it characteristics that make it difficult to influence the behavior of the target. Aside from pincher tip probing, the head with the tip removed can also be connected to a 2.54 mm pitch diameter connector.


Serial bus analysis function (option)

You can add on I2C, SPI, CAN, LIN, and other serial bus-specific trigger and analysis functions to your DL6000/DLM6000 series instrument. With these functions, you can trigger on specific serial bus parameters, and display the waveforms along with protocol analysis indicating the decoded serial bus information.

Moreover, the DL6000/DLM6000 series also comes with a "Serial Bus Auto-Setup" function to eliminate the tedious task of entering settings when starting the analysis.


Auto Setup Function for Serial Bus Analysis



DLM6000 Option 1



Display signal waveforms, protocol information, and decode information in real time
The DL6000/DLM6000's serial bus analysis function simultaneously displays these three pieces of information on screen in real time. You can link the protocol information with the waveform information, select data in the protocol list, and automatically display the corresponding part of the analog waveform. Check the protocol list to see whether transferred information is correct. If not, you can determine whether there were any electrical problems at the waveform level. In operational analysis of systems that include serial busses, this can be very useful for sorting out hardware from software problems.

DLM6000 Option 2

Analyzing two busses at once
Both analog and logic inputs can be used for serial bus analysis. Also, two different serial busses can be analyzed at the same time. For example, you can analyze a CAN and LIN bus simultaneously, or use an MSO to analyze two SPI busses at once.
Example: Behavioral analysis of an I2C control motor
You can trigger on specific data sent to a motor controller on an I2C bus and capture the waveform. Then, you can observe and analyze the content and timing of the data, plus the behavior of the activated motor. Together with that, you can use an MSO to observe control circuit logic signals, enabling you to evaluate the overall system.

Computation Functions

Digital filters, integrals, edge, rotary count, logic signal DA conversion computation, and FFT computation functions come standard. As these computations are hardware-based, results appear on screen quickly. Even computations that traditionally needed to be sent to a separate PC for processing can now be executed at high speed on the oscilloscope, thus greatly reducing the time and effort involved in computing and analyzing waveform data.

User defined MATH (option)

By combining basic math, trigonometric functions, differentials, digital filters,waveform parameters, and other values, you can define and execute equations and display the results along with the observed waveform


Power Supply Analysis Function (optional)

By using combinations of differential and current probes, you can evaluate switching loss or analyze safe operating area (SOA) in power supply waveforms. Through statistical computation you can also measure multiple switching waveforms and display loss on a per-week basis in lists and trends, or display statistics on aggregate loss of up to 2000 switching waveforms stored in History Memory. If precise calculations are required, a correction function and High Resolution mode are available.

Cycle-by-cycle switching loss statistics and trend display
It can be extremely useful to check for fluctuations in switching frequency or voltage modulated by the commercial power input voltage on screen, at the same time as the waveform of that input voltage. Fluctuations in cycle-by-cycle loss, peak current, and other phenomena can be checked in lists and trend graphs thereby allowing you to identify excessive changes from power-ON to stable operation.
