Mixed signal oscilloscope for complex systems testing

August 31, 2020 //By Ally Winning
Yokogawa has launched its latest generation of mixed signal oscilloscopes that feature options for four or eight analog inputs.

The DLM5000 has redesigned hardware to provide major improvements in both performance and operability. It features a sampling rate that is double that of the previous generation DLM4000.

The DLM5000’s capabilities make it ideal for many applications, including for mechatronics systems, such as ECUs, where numerous I/O analog, digital, and serial-bus waveforms need to be measured. The ability to monitor eight analog channels and up to 32-bits of logic input (16 as standard plus 16 optional) and perform protocol analysis simultaneously, such as UART, I2C, SPI, CAN, CAN FD, LIN, CXPI, SENT and FlexRay allows the DLM5000 to speed up product development.

A new feature, DLMsync, which will be available soon, allows two DLM5000s to work together to extend measurements for even more information. The feature allows the connection of two DLM5000s with a dedicated cable enables sampling clock and trigger synchronous measurement of up to 16 analog channels (8 + 8) plus 64 bit logic.

The DLM5000 can be used as an eight analog and 16 digital input mixed signal oscilloscope, with all channels able to be used simultaneously. With the /L32 option, up to 32 logic signals can be measured. Also included are a Bus/State display and an optional DA calculation function.

The DLM5000 has low residual noise, extensive voltage ranges and a variety of real-time low pass filters for better signal fidelity.

The device’s responsive 12.1-inch touchscreen allows easy monitoring of waveforms, not only when inputting eight channels, but also when the number of waveforms is increased by calculation or zooming. The DLM5000 also provides a traditional oscilloscope panel for easier navigation.

The DLM5000’s memory can save up to 100,000 captured waveforms. The History function allows the display of one or all of the captured waveforms on screen for cursor measurement, computation, and other operations. It also allows the analysis of rarely-occurring abnormal signals, even when an appropriate trigger condition is hard to find.
