The DLM4000 is a unique to the industry eight-channel mixed-signal oscilloscope suitable to test and debugging applications in the embedded systems, power electronics, mechatronics, and automotive sectors. Available in both 350 MHz and 500 MHz models, the 2.5 GSa/sec DLM4000 features eight analog input channels. The eighth input channel features Flex MSO which converts to a 8-bit logic analyzer at the push of a button; add sixteen additional logic analyzer inputs as an option, for 24-bit logic analysis. Advanced measurement and analysis features such as power analysis and serial-bus analysis, digital filtering, user-defined math, and super-long record lengths (up to 125 Mega Points) make the DLM4000 a super powerful engineering tool. High-resolution 12.1-inch LCD display, compact landscape format, ergonomic and friendly user-interface make it easy to use.

    Typical Demanding Applications for the Eight-Channel DLM4000

    Motor Control & Inverter Circuit Development

    
    Key to efficient and reliable high-performance electric motors is the modern inverter design, or ‘Intelligent Power Module’. Multi-channel, high-speed waveform measurement is an absolute necessity. Four channels are simply NOT enough. Boasting eight true analog inputs, the DLM4000 empowers today’s engineer with a convenient and comprehensive measurement system.

     

    Electronic Control Unit & Mechatronic Test
    
    Numerous I/O analog, digital, and serial-bus waveforms surrounding the Electronic Control Unit (ECU) must be measured. The DLM4000 offers ample channel-count and architecture to monitor eight analog channels and up to 24-bits of logic input while simultaneously performing protocol analysis such as UART, I²C, SPI, CAN, LIN and FlexRay. The DLM4000 can speed up the R&D process.

    Power Supply & Power Coverter Test

    

    During the evaluation of power supply design, it is necessary to measure noise, ripple, voltage margin and current, as well as timing margins and the jitter of the startup-shutdown sequences. As the number of waveforms in modern power supply designs is increasing, especially for intelligent digitally-controlled power supplies, battery management systems, and wireless power supply systems- a four channel oscilloscope is not enough.

    
    Troubleshooting, Total System Test
    

    For laboratory and field troubleshooting, the ability to measure as many suspicious signals as possible enables quick solutions to be found. The 8 channels of the DLM4000 provide the capability to measure more signals at one time, both now and to meet future needs.

  • • FUNCTIONS

      Reliable Capture from Fast-Short Pulses to Long Recordings.

      For the fast-short waveforms, the Comprehensive Trigger Suite captures the waveforms you need! In addition to basic trigger functions such as Edge, State, and Pulse Width, advanced trigger types are provided-including Edge OR between multiple channels, Serial Bus trigger in which a combination of two bus signals is possible, or an A and B combination of different trigger types

      Best in Class Deep Memory & Architecture

      Extra Deep Memory (125 Mega-Points) Enables Long-Duration Measurement  For four-channel measurements in single shot mode, you can add the /M2 Memory expansion option, which provides up to 125 Mpoints of memory. Even at a fast sampling rate of 1.25 GS/s, records as long as 100 milli-seconds can be captured. Yokogawa’s proprietary ScopeCORE IC assures responsiveness even for long record lengths. ScopeCORE maintains responsive waveform display even during parametric measurements and waveform calculations and defines the architecture and power of the DLM4000. In order to find and display the desired parts of the signal within the deep memory, powerful waveform search and a unique dual-window zoom function are provided.

      Replay Waveforms So You Never Miss an Abnormal Waveform

      History Function
      

      With the DLM4000 Series, up to 20,000 previously captured waveforms can be saved in the automatically segmented acquisition memory without sacrificing acquisition speed. History Memory allows you to display one or all of the previously captured waveforms on screen. You can also perform cursor measurements, computation, and other operations on history waveforms.

      History Search Function

      With the DLM4000 Series, you can search the 20,000 previously captured waveforms for history waveforms that meet specified search criteria. You can also perform cursor measurement and other types of analysis on the search results.

      Replay Function

      Waveforms can be displayed one at a time, using the rotary knob. With the Replay function, history waveforms can be automatically played back, paused, and fast-forwarded.

      • OPTIONS & ACCESSORIES

        Power Supply Analysis Function (/G4)

        Example of Switching Loss Analysis:

                      
        

        The built-in algorithm fine tunes Power Loss calculations. User-specified parameters include devices such as IGBTs and MOSFETs.

        By dividing the long memory into segments, the Safe Operating Area can be analyzed and peak voltages between switching cycles can be compared using overlaying or one-by-one replay.

        Display a list of switching loss of each cycle and save the results.

        User-Defined Math (/G2)

        Example of the functions in the /G2 option: Duty cycle analysis for PWM waveform,F-V conversion, High-pass/Low-pass/Band-pass filtering, moving average, differential-integral, trigonometric, exponential-logarithm, arithmetic calculation of multiple channels, DA conversion of logic signals.

        Expansion of FFT Calculation: In addition to power spectrum, advanced FFT functions, such as coherence and transfer function calculations are available to detail frequency-domain analysis.

        Serial Bus Analysis Function (/F1, /F2, /F3, /F4, /F5, /F6)

        Auto-Setup Saves Time!	Hardware-Based Decoding	Dual Bus Analysis
        Intelligent auto-setup enables quick and easy setup. The bit-rate and voltage thresholds are set automatically.	Serial-Bus waveforms are processed in real-time by a dedicated processor. Decoded serial-bus data is displayed alongside the bus waveform in a user-selected format.	Many systems contain multiple serial buses. The DLM4000 analyses up to four different serial-bus types simultaneously.

        Accessories

        Easy Probing for Floating Signals: High Voltage Differential Probe	Wide Range of Current Measurement: Current Probe	Enables Precise Power Measurement: Deskew Correctional Signal Source
        The High Voltage Differential Probe range includes models such as the company PBDH0150 (1400/peak) as well as the 701926 (7 kVpeak).

        The PBDH1000 Differential Probe features high input-resistance, wide bandwidth, and a wide input-voltage range. The PBDH1000 is perfect for measuring the noise or surge voltage of in-vehicle high-speed serial bus waveforms, including CAN and FlexRay.	In some cases, high input resistance is important. Yokogawa offers two types of logic probes-the PBL100 (100 MHz), which has minimal loading, and the PBL250, ideal for probing high-speed logic waveforms.
