The Yokogawa DLM4038 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. The Yokogawa 350 MHz, 2.5 GSa/sec DLM4038 features eight analog input channels. The eighth input channel features Flex MSO which converts to an 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 250 Mega Points) make the DLM4038 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. 

The DLM4038 is the world’s first 8 channel oscilloscope providing comprehensive measurement and analysis capabilities for embedded, automotive, power and mechatronics applications. Representing decades of experience in providing quality test and measuring tools, the DLM4038 is designed to satisfy the wide-ranging needs of engineers today and in the future. The hardware optimized architecture in the DLM4038 enables measurements and signal processing to be carried out in real time. This means that signals from multiple channels are promptly captured and measurements are always performed and updated at high speed.

The number of analog and digital channels, their flexibility and the wealth of measurement and analysis features enable the DLM4038 to solve the broadest range of test requirements.

Via the straightforward interface, users can automatically or manually split the display to separate individual channel waveform while maintaining their full dynamic range. The details of signals can therefore be quickly analyzed irrespective of the number of channels in use.

As intelligent control permeates more and more sectors of the industry from consumer electronics to industrial drives, the signals that engineers need to look at for testing become faster and more complex. The DLM4038 delivers the features and performance that engineers need in an advanced oscilloscope.

Enabling two fully independent zoom windows allows users to analyze the cause and effect of abnormal behaviors over all input channels. Users can also view and compare the details and timing of different serial buses operating at different speeds. 

The DLM4038 can capture and replay up to 50000 individual acquisitions (/M3 option). These can be displayed one at a time or as an accumulation. Using the search and measurement functions, abnormal signals can therefore be quickly isolated, analyzed and precisely categorized without needing to carefully configure triggers to capture rare events. Search up to 50000 waveform history records based on detailed search parameters using the history search function.

The flexible MSO inputs are included as standard. This enables the DLM4038 to be converted to a 7 analog and 8 digital input MSO. With the /L16 option, up to 24 logic signals can be measured. Bus/State display and optional DA calculation function, which is useful for evaluating AD/DA converters, are also provided.

When just a specific event or abnormal waveform needs to be captured, the flexible and reliable triggering of the DLM4038 is the solution. 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.

30 waveform parameters from a total of 29 different types can be displayed simultaneously with a high update rate. In addition to the basic statistical analysis of repetitively measured parameters, the Yokogawa original “cycle statistic” and “history statistic” measurement functions help the advanced analysis of periodic mechatronic signals. To observe the fluctuations of measured parameters, it is possible to display them as trends. Period-to-period changes can then be easily seen.

The variation of parameters can also be displayed as histograms thus providing a visual method of assessing them statistically. Many types of display format are supported such as split, dual-zoom, XY, FFT, histogram etc.

The GO/NO-GO function can be used to test the results of parameter measurements, trigger conditions and other criteria and automatically save or print data, send an e-mail etc. Save time using unattended supervisory data acquisition.

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.

View detailed graphical explanations of the oscilloscope’s functions by pressing the “?” key. Functions and operations can be shown on screen without having to consult the user’s manual.

The Yokogawa DLM4038 includes a comprehensive suite of software tools to support and complement complex measurement tasks.
