New /M3 option adds 250MPoints memory to Yokogawa DLM2000 and DLM4000 MSOs

Yokogawa’s DLM2000 and DLM4000 mixed-signal oscilloscopes have been enhanced with longer memory options. DLMs

Fundamentally, larger memories offer two advantages. The first obvious point is that more memory allows a longer acquisition time. The second is that, for the same acquisition time, using a larger memory can result in a higher sample rate – which actually means that the effective bandwidth of the measurement is increased.

There is yet a third benefit of a larger memory, which comes into play if the whole memory is not required for a particular measurement. For example, if the oscilloscope is equipped with a one megapoint memory and the instrument is set to use 100k points, theoretically it could capture ten acquisitions before the memory needs to be overwritten. This is the basis of the “history memory” used in Yokogawa oscilloscopes. If the history memory capability is combined with a fast waveform acquisition rate, it becomes possible to capture occasional anomalies and analyse them without having to rearm and retrigger the DSO. The search features can be used to isolate individual waveform acquisitions, which means that not only can the anomaly be analysed on its own channel waveform but the other input channels can also be analysed to help identify the cause of the anomaly. Using this approach, Yokogawa is able to offer MSOs with two, four and eight channels.

About Yokogawa Test & Measurement

Yokogawa has been developing measurement solutions for 100 years, consistently finding new ways to give R&D teams the tools they need to gain the best insights from their measurement strategies. The company has pioneered accurate power measurement throughout its history, and is the market leader in digital power analysers.

Yokogawa instruments are renowned for maintaining high levels of precision and for continuing to deliver value for far longer than the typical shelf-life of such equipment. Yokogawa believes that precise and effective measurement lies at the heart of successful innovation – and has focused its own R&D on providing the tools that researchers and engineers need to address challenges great and small.

Yokogawa takes pride in its reputation for quality, both in the products it delivers – often adding new features in response to specific client requests – and the level of service and advice provided to clients, helping to devise measurement strategies for even the most challenging environments.

The guaranteed accuracy and precision of Yokogawa’s instruments results from the fact that Yokogawa has its own European standards laboratory at its European headquarters in The Netherlands. This facility is the only industrial (i.e. non-government or national) organisation in the world to offer accredited power calibration, at frequencies up to 100 kHz. ISO 17025 accreditation demonstrates the international competence of the laboratory.
