Adaptability is key in the development of high-performance and intelligent power semiconductor technologies and mechatronics in modern electric vehicles, motor controls, and energy efficient electronic designs. With up to 16 bits high resolution, best-in-class startup speed, and high noise immunity this four-channel oscilloscope provides an extensive set of analysis features in a compact design.
12- to 16-Bit High Resolution
Compared to traditional 8-bit oscilloscopes, the DLM3000HD measures 12-bit vertical resolution all the time. With its high-definition, resolution improves up to 16-bits, providing 16x more detail than existing high-definition oscilloscopes. Its high-resolution mode enables detailed measurement of events such as ringing and overshoot with impressive accuracy.
Multi-Channel Measurement Up to Eight Channels
A single DLM3000HD measures up to four channels simultaneously, while connecting two instruments extends synchronous measurement up to eight channels to enable evaluations via a single test.
Wide Bandwidth Measurement
Momentary phenomena such as overshoot at the rise of a high-speed inverter cannot be verified with low bandwidth oscilloscopes. The DLM3000HD combines a wide bandwidth of up to 500 MHz with a sample rate up to 2.5 GS/s.
Up to 2.5 GS/s (Four Channels at Once), Up to 1 G Points Memory
The DLM3000HD has a memory that can capture up to 1 G points (odd channels only) in a single waveform and up to 125 M points in a repetitive waveform acquisition to enable long time measurement without reducing the sample rate.
Intuitive and Highly-Responsive Touchscreen
The 8.4in intuitive and highly-responsive touchscreen is useful for observing analog signals in detail and displaying information for debugging like parameters, zoom, XY display, and FFT analysis results.
Quick Startup
The DLM3000HD starts up from OFF to waveform display in twelve seconds for a quicker start on projects.
Link with a PC
It is often more effective and efficient to perform analysis using a PC because of its high CPU processing power. This can be accomplished with the DLM3000HD through integration with the IS8000 Integrated Test and Measurement Software Platform for multiple waveform and power measurement results and powerful analysis capabilities.
History and Search
Automatically save previously captured waveforms with the DLM3000HD series, up to 200,000 previously captured waveforms can be saved in the acquisition memory. Display one or all of the previously captured waveforms (history waveforms) on screen and perform cursor measurement, computation, and other operations. Users can analyze rarely-occurring abnormal signals even when an appropriate trigger condition is difficult to find because its waveform shapes are not constant. Multiple intuitive search methods are also available. For example, you can specify a rectangular zone that captures a part of a waveform on the screen, a zone that covers an entire measured waveform, or a polygonal zone. If you know a value of interest, such as an abnormal value of voltage or pulse width, you can search history waveforms using waveform parameters.
Zoom and Search
Multi-channel waveforms captured in the long memory need to be zoomed in vertically and horizontally for detailed viewing. The touchscreen plus dedicated zoom keys and knob allow you to quickly zoom in on aspects you wish to see. You can display two zoomed waveforms with different time axis scales at the same time and use Auto Scroll to sweep the zoom window across the waveforms automatically. The ability to zoom in on two distant locations at the same time (like “cause” and “effect” of an event) or to display them with different zoom factors is very useful for software debugging. Users can also search using multiple criteria to automatically find and zoom into features in the waveform for further inspection. The locations of the found waveforms are marked on screen.
Logic Signal Measurement and Serial Bus Analysis
Equipped with 8-bit logic input as standard. Bus/State display and optional DA calculation functions (useful for AD/DA converters evaluation) are also provided.
Triggers
The DLM3000HD’s boasts easy-to-configure triggers such as Edge, Enhanced, and B triggers and can combine analog and logic inputs.
Filters
Real-time filters with optimum noise reduction support a wide range of frequencies from 8 kHz to 200 MHz. Each channel has 15 low pass filters available with cutoff frequencies from 8 kHz to 200 MHz and waveforms are filtered prior to storage in memory. These real-time filters allow for stable triggering of superimposed noise signals.
DLMsync Two-Unit Connection for More Channels (/SY)
Connecting two DLM3000HD Series models (with /SY option) with a dedicated cable (701982) enables synchronous measurement up to eight channels. Captured waveforms display on each unit, triggers operate in common, and common items (record length, sample rate, acquisition settings, horizontal axis scale settings) are linked like a single oscilloscope unit. Two synchronized instruments become linked and some operations are shared between the main unit and the sub unit. For example, if you zoom in on a waveform on the main or sub unit, the corresponding waveform on the other unit will automatically get zoomed in at the same spot. As measurement data can be output in batches, eight channels can be checked at once in combination with the IS8000 Integrated Test and Measurement Software Platform.
IEEE1588 Integrated Measurement Master (/CY)
The DLM3000HD can be set as the master unit for time-synchronized measurement using IEEE1588. This function connects measuring instruments in a LAN network to each other without a dedicated cable or complex settings typically required for synchronization, which allows users to start synchronized measurements easily. If using a network HUB, be sure to use an IEEE1588-supported version. All measured data and results can be integrally analyzed on the same time axis on using IS8000.
Flexible MSO Input
The DLM3000HD can convert 4th channel analog input to 8-bit logic and function as a three-channel analog combined with an 8-bit logic MSO (mixed signal oscilloscope). Along with observing data and serving as trigger sources, the logic inputs are also used for serial bus analysis such as I2C-bus and SPI-bus. (Logic inputs require a separate logic probe.)
High Voltage Switching Motor/Inverter Circuits Development
The high-definition oscilloscope DLM3000HD is ideal for measuring fast switching of inverters. It measures four channels simultaneously up to 2.5 GS/s with bandwidths up to 500 MHz and provides high-precision analysis with 12-bit resolution. In addition, DLMsync enables uncomplicated connection of two DLM3000HD Series models to allow evaluation tests to be completed all at once through multi-point measurements. The SW Loss Math Function is effective for inverter characterization and provides powerful analysis support. A full line of accessories for high voltages is also available.
Example: Simultaneous measurement of hree line voltages and three phase currents of a three-phase motor along with gate control signals of six SiCs in an inverter
Automotive Electronic Control Unit and Mechatronics Embedded Device Development
Digital waveform analysis using logic inputs alone cannot reveal anomalies such as voltage drift, noise, distortion or ringing, and measure rise-fall times. Electronic control unit (ECU) testing requires stringent examination of all digital waveforms and analog input channels are best for this job. Numerous I/O analog, digital, and serial-bus waveforms surrounding the ECU must be measured. The DLM3000HD offers ample channel-count and architecture to monitor four analog channels and up to 8-bits of logic input while simultaneously performing protocol analysis such as UART, I2C, SPI, CAN, CAN FD, LIN, CXPI, PSI5, and FlexRay.
Example: Measurement of controller I/O signals and serial bus signals simultaneously along with analog behavior
UART (RS232) /I2C/SPI/CAN/CAN FD/LIN/FlexRay/SENT/CXPI/PSI5 Airbag
Dedicated trigger and analysis options are available for various serial buses of both in-vehicle and embedded systems. Logic input can also be used for I2C/SPI/UART/SENT. When not necessary to observe waveform quality of a bus, decoding or analysis using logic inputs is possible.
Unique Auto Setup
Yokogawa Test&Measurement’s proprietary Auto Setup function automatically analyzes the input signal or captured waveforms and complex parameters such as bit rate and threshold level and selects the optimal settings in seconds. This saves time and is a powerful debugging feature when bit rate and other parameters are unknown.
Simultaneous Analysis (Up to Four Buses)
Perform high-speed simultaneous analysis on up to four different serial buses operating at different speeds. Extensive search capabilities enhance the usability and allow users to find specific data in very long memory. Use dual-zoom means view different buses and debug alongside each other.
Equations can be arbitrarily created using a suite of operators such as trigonometric and logarithmic operators, integration and differntiation, pulse width operators, phase measurement, and digital-to-analog conversion.
Switching Loss Analysis
Calculate switching loss [ V ( t ) × i ( t ) ] over long test cycles utilizing the long built-in memory. A wide variety of switching loss analyses are supported, including turn-on/off loss calculation, loss including continuity loss, and loss over long cycles of 50 Hz/60 Hz power line.
Power Parameter Measurement
Measure power parameters automatically for up to two pairs of voltage and current waveforms, such as active power, apparent power, power factor, and more. Cycle statistics and history statistics can also be calculated.

While accurate rise time measurements have become easier to make, it remains, nonetheless, quite easy to overlook error contributions due to not only the oscilloscope but also the probe. And, while the error contributed by a scope's finite step-response (rise time) is often accounted for, that contributed by the probe is often overlooked.
