Yokogawa Introduces the DLM5000 Series of Mixed Signal OscilloscopesSeptember 09, 2020 by Gary Elinoff
The 350 MHz and 500 MHz models are aimed at applications in automotive, mechatronics, and electronics R&D.
Yokogawa’s DLM5000 oscilloscopes evolved from the company’s popular eight-channel DLM4000 series mixed signal devices and are designed to be used in conjunction with Yokogawa ScopeCorders, power analyzers and other related devices. A soon to be released DLMsync option will facilitate taking measurements from two connected DLM5000 oscilloscopes simultaneously.

The Need for Simultaneous Measurement of Multiple Data Channels
The recent explosion of solar power devices such as inverters and specialty motors, as well as automotive applications including the electronic control units (ECUs) required by advanced driver-assistance systems (ADAS) has driven the need for multichannel oscilloscopes. Developments in these fields also require measurement devices to store and work with vast amounts of data.
The DLM5000 series, like its predecessor DLM4000 devices, have evolved to fill these critical needs.
Members of the DLM5000 series have either four or eight analog input channels. Thus, with a single DLM5000 oscilloscope, up to eight analog signals can be simultaneously viewed, along with inputs from and a 16 bit logic channel, with an optional 32 bit logic capability. The maximum sampling rate is 2.5 GS/s, a twofold improvement over the previous DLM4000 series.
The anticipated DLMsync function will enable customers to couple two DLM5000 oscilloscopes, doubling the number of analog and logic channels that can be measured. This feature will be a boon to engineers charged with debugging embedded systems.
Improved Analytic Capability
The DLM5000 series of devices incorporate a waveform processing engine to speed up data analysis and the graphical expression of waveforms. Support for USB 3.0 for will eliminate data transfer bottlenecks.
The DLM5000 series is configured to respond to a large set of electrical triggers. And, with an eye to advanced automotive work, the devices incorporate a specific trigger function that supports the CXPI in-vehicle LAN standard. With this functionality, both the trigger and the captured waveform can be simultaneously displayed to facilitate analysis.

Advanced Debugging Capabilities
A boon to the debugging process, the peak detection function can automatically detects spurious frequencies. This is a tremendous to engineers searching for the sources and causes of troublesome anomalies, such as clock and power supply switching noise.
Members of the DLM5000 series can perform as many as four FFT analyses simultaneously. Furthermore, FFTs can be performed not only on the actual waveforms obtained directly from channels one to eight, but also on computed waveforms.
The DLM5000s will be able to store up to 500 million data points and retain up to 100 thousand waveforms. These capabilities are double that of the previous DLM4000s.
While the large scale adaptation of all-electric vehicles will have to wait for satisfactory batteries, the electrification of hybrids and well as purely gasoline powered vehicles proceeds apace. High speed control signals must be captured and analyzed on a GS/s scale, and the behavior of brakes system signals must be captured every several milliseconds.
As such, the DLM5000 will be an invaluable aid to designers of automotive systems, particularly for ADAS developers, because of the ability to work directly with automotive bus systems based on in-vehicle standards such as CAN and CAN FD.
