Yokogawa adds new features to its mixed-signal oscilloscopes

LinkedIn +

Yokogawa has added new trigger and analysis options to its DLM2000 (four-channel) and DLM4000 (eight-channel) mixed-signal oscilloscopes (MSOs) for testing the latest generation of in-vehicle serial buses.

The new options are designed to address measurement challenges posed by the CAN FD (CAN with flexible data rate) and SENT (single edge nibble transmission) bus systems.

When equipped with the new serial bus options, the Yokogawa MSOs will decode the bus signals and display the results in real time. A wide variety of dedicated triggers and search functions are available to aid analysis and troubleshooting on parameters that can affect the bus signals.

The Yokogawa DLM series of oscilloscopes are ideally suited to this type of analysis because of the versatility provided by their long memory. The length of the acquisition memory in Yokogawa’s DLM4000 mixed-signal eight-channel oscilloscope is up to 250 Mpoints, making the handling of the extended data frames used in the CAN FD bus – which enable the bit rate inside a frame to be changed flexibly – a straightforward task. This memory also makes it possible to display trend data over extended periods, up to 100 seconds of data for SENT signals with microsecond duration, for example.
