Flexible MSO Input

  • Capture a mixed signals of analog and logic signals
    — 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)
  • The performance of up to 11 inputs by converting to logic-
    — Using logic input, up to 11 input signals can be observed simultaneously as 3 ch of analog and 8-bit logic. It is not only possible to use logic input for observation of data and control signals, or as a trigger source, but also for logic
  • Sophisticated waveform acquisition engine-
    — With long memory and the History function, you’ll never miss an historical waveform. A variety of trigger functions reliably capture the waveforms you want.

History Function -

  • You can replay waveforms later on, so you’ll never miss an abnormal waveform -
    —With the DLM2000 series, up to 20,000 previously captured waveforms can be saved in the acquisition memory. With the 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.
  • History Search Function
    — You can search the up to 20,000 previously captured waveforms for history waveforms that meet certain conditions. You can perform cursor measurement and other analyses on the found waveforms.
  • Replay Function
    —Waveforms can be displayed in order, one at a time, by using the rotary knob. With the Replay function, history waveforms can be automatically played back, paused, fast-forwarded, and rewound.

Capture & Display Zoom and Search Functions

Never miss the waveforms you want to capture.

  • Real time Filter with optimum noise reduction (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.
  • 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
  • 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
    Cutoff Frequency Setting Range:
    0.01 Hz to 500 MHz

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
  • Waveform 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 20,000 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.

Real Time Filter and High Resolution Mode

  • 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.
  • 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.
  • 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 of a button
    —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.
  • 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.

Serial bus analysis function (/F1, /F2, /F3, /F4, /F5, /F6) – FlexRay/UART/CAN/LIN/I²C/SPI

Triggers for FlexRay, UART, CAN, LIN, I²C, and SPI 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 and LIN).

  • Simultaneous analyses of different busses
    — Two busses can be analyzed simultaneously. Waveforms and analysis results from busses with different speeds can be displayed in individual Zoom screens with different scales..
  • A wealth of trigger functions:
    — A wide variety of trigger conditions can be set, such as ID/Data trigger combinations and combinations of serial bus triggers with normal edge triggers.

Power Supply Analysis Option (/G4)

Dedicated power supply analysis options are available (4 ch models only) for switching loss, joule integral (i2t), SOA (safe operating area) analysis, harmonic analysis of power supply current based on EN61000-3-2, and other operations.

  • Switching Loss Analysis
    — Voltage and current waveforms can be input to the 62.5 MW (max.) long memory (/M2 models) for computation of switching loss (V(t) xi(t)). A wide variety of switching loss analyses are supported, including turn-on/off loss calculation, loss including continuity loss, and loss over long cycles (50 Hz/60Hz).
  • Harmonic Analysis of Power Supply Current
    —Harmonics determined by the IEC standard that are generated by the target device can be judged for each applicable class (classes A-D). Bar graphs and lists can be displayed for comparing harmonic current limit values with values calculated from actually measured signals.
